The B490 is our hardest-working, go-to microscope. The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock.
This darkfield microscope provides enhanced contrast at low and intermediate magnifications. High quality optics and precision mechanics have made this time-tested design a favorite for labs across many industries. Specialized darkfield optics allow you to observe live cells including blood and other fluids.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.
The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.

Packing List:
The B490 is our hardest-working, go-to microscope. The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock.
This darkfield microscope provides enhanced contrast at low and intermediate magnifications. High quality optics and precision mechanics have made this time-tested design a favorite for labs across many industries. Specialized darkfield optics allow you to observe live cells including blood and other fluids.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.
The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.
Monitor and capture photos and videos with the included 1.2MP USB2.0 camera. The ultra-sensitive back-illuminated sensor is designed to excel at low-light imaging, making it ideal for fluorescence and darkfield microscopy. A 0.37X reduction lens is included to capture more of the microscope's field-of-view. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.

Packing List:
The B490 is our hardest-working, go-to microscope. The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock.
This darkfield microscope provides enhanced contrast at low and intermediate magnifications. High quality optics and precision mechanics have made this time-tested design a favorite for labs across many industries. Specialized darkfield optics allow you to observe live cells including blood and other fluids.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 16X eyepieces expand the maximum magnification to 1600X with 8 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.
The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.
Monitor and capture photos and videos with the included 1MP digital eyepiece camera. The compact, lightweight camera can be used in place of an eyepiece to watch live images, and to record photos or videos on your computer. This ability to view microscopic images on your computer reduces eye-strain, and allows groups of people to view images at the same time. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.

Packing List:
The B490 is our hardest-working, go-to microscope. The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock.
This darkfield microscope provides enhanced contrast at low and intermediate magnifications. High quality optics and precision mechanics have made this time-tested design a favorite for labs across many industries. Specialized darkfield optics allow you to observe live cells including blood and other fluids.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 16X eyepieces expand the maximum magnification to 1600X with 8 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.
The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.
Monitor and capture photos and videos with the included 3.1MP USB2.0 camera. The highly-sensitive back-illuminated sensor is designed for improved low-light imaging, making it suitable for fluorescence and darkfield microscopy. A 0.37X reduction lens is included to capture more of the microscope's field-of-view. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.

Packing List:
The B490 is our hardest-working, go-to microscope. The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock.
This darkfield microscope provides enhanced contrast at low and intermediate magnifications. High quality optics and precision mechanics have made this time-tested design a favorite for labs across many industries. Specialized darkfield optics allow you to observe live cells including blood and other fluids.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 20X eyepieces expand the maximum magnification to 2000X with 8 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.
The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.
Monitor and capture photos and videos with the included 3MP digital eyepiece camera. The compact, lightweight camera can be used in place of an eyepiece to watch live images, and to record photos or videos on your computer. This ability to view microscopic images on your computer reduces eye-strain, and allows groups of people to view images at the same time. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.

Packing List:
The B490 is our hardest-working, go-to microscope. The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock.
This darkfield microscope provides enhanced contrast at low and intermediate magnifications. High quality optics and precision mechanics have made this time-tested design a favorite for labs across many industries. Specialized darkfield optics allow you to observe live cells including blood and other fluids.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 25X eyepieces expand the maximum magnification to 2500X with 6 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.
The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.

It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock.
This darkfield microscope provides enhanced contrast at low and intermediate magnifications. High quality optics and precision mechanics have made this time-tested design a favorite for labs across many industries. Specialized darkfield optics allow you to observe live cells including blood and other fluids.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 25X eyepieces expand the maximum magnification to 2500X with 6 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.
The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.
Monitor and capture photos and videos with the included 1.2MP USB2.0 camera. The ultra-sensitive back-illuminated sensor is designed to excel at low-light imaging, making it ideal for fluorescence and darkfield microscopy. A 0.37X reduction lens is included to capture more of the microscope's field-of-view. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.

The B490 is our hardest-working, go-to microscope. The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock.
This darkfield microscope provides enhanced contrast at low and intermediate magnifications. High quality optics and precision mechanics have made this time-tested design a favorite for labs across many industries. Specialized darkfield optics allow you to observe live cells including blood and other fluids.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.
The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.

High quality optics and precision mechanics have made this time-tested design a favorite for labs across many industries. Specialized darkfield optics allow you to observe live cells including blood and other fluids.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.
The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.
Monitor and capture photos and videos with the included 3MP digital eyepiece camera. The compact, lightweight camera can be used in place of an eyepiece to watch live images, and to record photos or videos on your computer. This ability to view microscopic images on your computer reduces eye-strain, and allows groups of people to view images at the same time. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.

The B490 is our hardest-working, go-to microscope. The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock.
This darkfield microscope provides enhanced contrast at low and intermediate magnifications. High quality optics and precision mechanics have made this time-tested design a favorite for labs across many industries. Specialized darkfield optics allow you to observe live cells including blood and other fluids.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 16X eyepieces expand the maximum magnification to 1600X with 8 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.
The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.

The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.
Monitor and capture photos and videos with the included 1.2MP USB2.0 camera. The ultra-sensitive back-illuminated sensor is designed to excel at low-light imaging, making it ideal for fluorescence and darkfield microscopy. A 0.37X reduction lens is included to capture more of the microscope's field-of-view. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.

This is particularly useful for observing live cells including blood analysis.
Monitor and capture photos and videos with the included 1MP digital eyepiece camera. The compact, lightweight camera can be used in place of an eyepiece to watch live images, and to record photos or videos on your computer. This ability to view microscopic images on your computer reduces eye-strain, and allows groups of people to view images at the same time. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.

Packing List:
The B490 is our hardest-working, go-to microscope. The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock.
This darkfield microscope provides enhanced contrast at low and intermediate magnifications. High quality optics and precision mechanics have made this time-tested design a favorite for labs across many industries. Specialized darkfield optics allow you to observe live cells including blood and other fluids.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 20X eyepieces expand the maximum magnification to 2000X with 8 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.
The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.

The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.
Monitor and capture photos and videos with the included 3.1MP USB2.0 camera. The highly-sensitive back-illuminated sensor is designed for improved low-light imaging, making it suitable for fluorescence and darkfield microscopy. A 0.37X reduction lens is included to capture more of the microscope's field-of-view. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.

Packing List:
The B490 is our hardest-working, go-to microscope. The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock.
This darkfield microscope provides enhanced contrast at low and intermediate magnifications. High quality optics and precision mechanics have made this time-tested design a favorite for labs across many industries. Specialized darkfield optics allow you to observe live cells including blood and other fluids.
To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain.
The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 25X eyepieces expand the maximum magnification to 2500X with 6 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level.
The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
A dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.
Monitor and capture photos and videos with the included 5MP digital eyepiece camera. The compact, lightweight camera can be used in place of an eyepiece to watch live images, and to record photos or videos on your computer. This ability to view microscopic images on your computer reduces eye-strain, and allows groups of people to view images at the same time.
