We offer a wide variety of Cameras for every application - from student to professional use:

Select a type of camera - Eyepiece, USB 2.0 or USB 3.0 - to name the most popular choices

Choose the Megapixels of the camera - the higher the megapixel count on a camera sensor the greater the amount of detail that can be captured in an image

Magnification
Camera Type
Camera Pixels

The Higher the Magnification - The More Detail You'll See

Magnification 40x
Magnification 1000x
Magnification 2500x

Magnification is the ability of your microscope to make small objects seem larger. As the magnification increases the area being viewed will be decrease is size but the detail of the area being viewed will improve.

Amscope microscopes come with multiple magnifications to aid you in finding the proper magnification for viewing each specimen.

Camera Connection Types

When comparing 2.0 and 3.0 there are few major differences. First the transfer rates. USB 2.0 offers transfer rates of 480 Mbps and USB 3.0 offers transfer rates of 4.8 Gbps - that's 10 times faster.

Camera Resolution

The most important factor in ensuring successful microscopic imaging is choosing the appropriate optics and camera for your application that gives you more data and higher image quality. When selecting a microscope camera, it is best to base your decision on the most important requirements for your microscopic observation.

The PZ620T is an indispensable instrument for mineralogists, pathologists, and any laboratory that needs a polarizing microscope that delivers on quality and versatility. The microscope is equipped to handle polarization for transmitted and reflected illumination, with a rotating stage and Bertrand lens for in-depth mineral analysis. High-power incandescent illumination and strain-free optics ensure optimal image quality for both orthoscopic and conoscopic observation over a large magnification range with seven included objective lenses.

Viewing Head

The microscope's head is designed for precision and comfort. The super-widefield optics provide a larger field-of-view so you can see more specimen at any magnification. Compensation-free Siedentopf interpupillary adjustment allows any user to properly align the oculars without readjusting focus. For users with astigmatism or asymmetrical vision, the left ocular can be adjusted to fine-tune focus. The photo port is equipped with a 23mm tube for attaching cameras with compensating lenses, and is height-adjustable to match focus with the eyepieces. The port is compatible with our YX series C-mount adapters which can attach directly to C-mount cameras without a compensating lens – ideal for 1” format sensors. The head is set to a 30° incline which is ideal for viewing from a standing position, and it can be rotated 360°.

Betrand Lens

The Bertand lens allows the user to quickly switch between normal orthoscopic and conoscopic observation. This is required to shift to the rear focal plane for proper alignment of the aperture diaphragm, and to observe interference patterns created by minerals under polarized light. The lens assembly has a slot for the included first-order, quarter-wave, and quartz-wedge retardation plates.

Optics

The infinity-corrected optical system eliminates optical errors when using filters and other in-line components, which is of paramount importance in polarized-light microscopy. The quintuple objective turret provides instant access to 5 magnification levels to efficiently move through magnifications from 50X to 1000X. Seven objective lenses are provided ranging from 5X to 100X, with both oil and dry 100X lenses. The turret's reversed orientation provides more working room above the stage. These high-quality lenses are strain-free to ensure accurate observation under polarized light, with plan-achromatic corrections to improve resolution and field flatness for edge-to-edge sharpness. Each objective mount can be independently centered to ensure proper alignment.

The Stage

The stage is designed for precise sample placement, with full stage centering and a dual-axis mechanical caliper which can accommodate varying specimen sizes. Once centered, the specimen can be rotated to locate its axis and tested for birefringence. The sub-stage polarizer can also be rotated to avoid stage movement when working with specimens with weaker birefringence.

Koehler Transmitted Illumination

Built on Koehler illumination principals, the sub-stage lighting provides evenly-distributed light for optimal contrast. The rear-mounted 100W incandescent light-source provides 100 CRI illumination with ample brightness for contrast-enhancement methods like darkfield. The lower color temperature of the halogen light-source causes less eyestrain compared to high-Kelvin LED. The light condenser uses a swing mechanism for optimized lighting at both high and low magnifications, with a NA0.25 setting for full coverage at extremely low magnifications. An iris diaphragm allows you to adjust the aperture to optimize contrast and depth-of-field. The condenser holder has an integrated, rotatable polarizer for diascopic polarization. It uses rack-and-pinion height adjustment for precision control, and is centerable for proper alignment. The condenser is top-mounted for easier replacement when working with additional condensers. The illuminator's field lens provides an iris diaphragm to control light-spread, optimizing contrast and definition in specimen features.

Koehler Reflected Illumination

The top illuminator also uses a 100W incandescent light-source to provide ample light for use with polarization. Adjustable aperture and field diaphragms offer precise control over the light field for improved contrast and edge sharpness. A removable polarizer board provides polarization for reflected illumination. The analyzer is equipped with a dial to control the angle of cross-polarization.

  • The PZ620T is an indispensable instrument for mineralogists, pathologists, and any laboratory that needs a polarizing microscope that delivers on quality and versatility. The microscope is equipped to handle polarization for transmitted and reflected illumination, with a rotating stage and Bertrand lens for in-depth mineral analysis. High-power incandescent illumination and strain-free optics ensure optimal image quality for both orthoscopic and conoscopic observation over a large magnification range with seven included objective lenses.

    Viewing Head

    The microscope's head is designed for precision and comfort. The super-widefield optics provide a larger field-of-view so you can see more specimen at any magnification. Compensation-free Siedentopf interpupillary adjustment allows any user to properly align the oculars without readjusting focus. For users with astigmatism or asymmetrical vision, the left ocular can be adjusted to fine-tune focus. The photo port is equipped with a 23mm tube for attaching cameras with compensating lenses, and is height-adjustable to match focus with the eyepieces. The port is compatible with our YX series C-mount adapters which can attach directly to C-mount cameras without a compensating lens – ideal for 1” format sensors. The head is set to a 30° incline which is ideal for viewing from a standing position, and it can be rotated 360°.

    Betrand Lens

    The Bertand lens allows the user to quickly switch between normal orthoscopic and conoscopic observation. This is required to shift to the rear focal plane for proper alignment of the aperture diaphragm, and to observe interference patterns created by minerals under polarized light. The lens assembly has a slot for the included first-order, quarter-wave, and quartz-wedge retardation plates.

    Optics

    The infinity-corrected optical system eliminates optical errors when using filters and other in-line components, which is of paramount importance in polarized-light microscopy. The quintuple objective turret provides instant access to 5 magnification levels to efficiently move through magnifications from 50X to 1000X. Seven objective lenses are provided ranging from 5X to 100X, with both oil and dry 100X lenses. The turret's reversed orientation provides more working room above the stage. These high-quality lenses are strain-free to ensure accurate observation under polarized light, with plan-achromatic corrections to improve resolution and field flatness for edge-to-edge sharpness. Each objective mount can be independently centered to ensure proper alignment.

    The Stage

    The stage is designed for precise sample placement, with full stage centering and a dual-axis mechanical caliper which can accommodate varying specimen sizes. Once centered, the specimen can be rotated to locate its axis and tested for birefringence. The sub-stage polarizer can also be rotated to avoid stage movement when working with specimens with weaker birefringence.

    Koehler Transmitted Illumination

    Built on Koehler illumination principals, the sub-stage lighting provides evenly-distributed light for optimal contrast. The rear-mounted 100W incandescent light-source provides 100 CRI illumination with ample brightness for contrast-enhancement methods like darkfield. The lower color temperature of the halogen light-source causes less eyestrain compared to high-Kelvin LED. The light condenser uses a swing mechanism for optimized lighting at both high and low magnifications, with a NA0.25 setting for full coverage at extremely low magnifications. An iris diaphragm allows you to adjust the aperture to optimize contrast and depth-of-field. The condenser holder has an integrated, rotatable polarizer for diascopic polarization. It uses rack-and-pinion height adjustment for precision control, and is centerable for proper alignment. The condenser is top-mounted for easier replacement when working with additional condensers. The illuminator's field lens provides an iris diaphragm to control light-spread, optimizing contrast and definition in specimen features.

    Koehler Reflected Illumination

    The top illuminator also uses a 100W incandescent light-source to provide ample light for use with polarization. Adjustable aperture and field diaphragms offer precise control over the light field for improved contrast and edge sharpness. A removable polarizer board provides polarization for reflected illumination. The analyzer is equipped with a dial to control the angle of cross-polarization.

    Digital Imaging

    Monitor and capture photos and videos with the included 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 for use with 23mm-30.5mm ports 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 PZ620T is an indispensable instrument for mineralogists, pathologists, and any laboratory that needs a polarizing microscope that delivers on quality and versatility. The microscope is equipped to handle polarization for transmitted and reflected illumination, with a rotating stage and Bertrand lens for in-depth mineral analysis. High-power incandescent illumination and strain-free optics ensure optimal image quality for both orthoscopic and conoscopic observation over a large magnification range with seven included objective lenses.

    Viewing Head

    The microscope's head is designed for precision and comfort. The super-widefield optics provide a larger field-of-view so you can see more specimen at any magnification. Compensation-free Siedentopf interpupillary adjustment allows any user to properly align the oculars without readjusting focus. For users with astigmatism or asymmetrical vision, the left ocular can be adjusted to fine-tune focus. The photo port is equipped with a 23mm tube for attaching cameras with compensating lenses, and is height-adjustable to match focus with the eyepieces. The port is compatible with our YX series C-mount adapters which can attach directly to C-mount cameras without a compensating lens – ideal for 1” format sensors. The head is set to a 30° incline which is ideal for viewing from a standing position, and it can be rotated 360°.

    Betrand Lens

    The Bertand lens allows the user to quickly switch between normal orthoscopic and conoscopic observation. This is required to shift to the rear focal plane for proper alignment of the aperture diaphragm, and to observe interference patterns created by minerals under polarized light. The lens assembly has a slot for the included first-order, quarter-wave, and quartz-wedge retardation plates.

    Optics

    The infinity-corrected optical system eliminates optical errors when using filters and other in-line components, which is of paramount importance in polarized-light microscopy. The quintuple objective turret provides instant access to 5 magnification levels to efficiently move through magnifications from 50X to 1000X. Seven objective lenses are provided ranging from 5X to 100X, with both oil and dry 100X lenses. The turret's reversed orientation provides more working room above the stage. These high-quality lenses are strain-free to ensure accurate observation under polarized light, with plan-achromatic corrections to improve resolution and field flatness for edge-to-edge sharpness. Each objective mount can be independently centered to ensure proper alignment.

    The Stage

    The stage is designed for precise sample placement, with full stage centering and a dual-axis mechanical caliper which can accommodate varying specimen sizes. Once centered, the specimen can be rotated to locate its axis and tested for birefringence. The sub-stage polarizer can also be rotated to avoid stage movement when working with specimens with weaker birefringence.

    Koehler Transmitted Illumination

    Built on Koehler illumination principals, the sub-stage lighting provides evenly-distributed light for optimal contrast. The rear-mounted 100W incandescent light-source provides 100 CRI illumination with ample brightness for contrast-enhancement methods like darkfield. The lower color temperature of the halogen light-source causes less eyestrain compared to high-Kelvin LED. The light condenser uses a swing mechanism for optimized lighting at both high and low magnifications, with a NA0.25 setting for full coverage at extremely low magnifications. An iris diaphragm allows you to adjust the aperture to optimize contrast and depth-of-field. The condenser holder has an integrated, rotatable polarizer for diascopic polarization. It uses rack-and-pinion height adjustment for precision control, and is centerable for proper alignment. The condenser is top-mounted for easier replacement when working with additional condensers. The illuminator's field lens provides an iris diaphragm to control light-spread, optimizing contrast and definition in specimen features.

    Koehler Reflected Illumination

    The top illuminator also uses a 100W incandescent light-source to provide ample light for use with polarization. Adjustable aperture and field diaphragms offer precise control over the light field for improved contrast and edge sharpness. A removable polarizer board provides polarization for reflected illumination. The analyzer is equipped with a dial to control the angle of cross-polarization.

    Digital Imaging

    Monitor and capture photos and videos with the included 1.2MP USB3.0 camera. With extraordinary sensitivity and high framerates, the MU123-FL provides high-definition imaging for low-light applications, including fluorescence and darkfield. Using a cutting-edge 1.2MP back-illuminated CMOS sensor with an incredible 2040mV sensitivity (1/30s), high gain-levels can be used for highly-responsive realtime video. A 0.37X reduction lens is included for use with 23mm-30.5mm ports 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 lens assembly has a slot for the included first-order, quarter-wave, and quartz-wedge retardation plates.

    Optics

    The infinity-corrected optical system eliminates optical errors when using filters and other in-line components, which is of paramount importance in polarized-light microscopy. The quintuple objective turret provides instant access to 5 magnification levels to efficiently move through magnifications from 50X to 1000X. Seven objective lenses are provided ranging from 5X to 100X, with both oil and dry 100X lenses. The turret's reversed orientation provides more working room above the stage. These high-quality lenses are strain-free to ensure accurate observation under polarized light, with plan-achromatic corrections to improve resolution and field flatness for edge-to-edge sharpness. Each objective mount can be independently centered to ensure proper alignment.

    The Stage

    The stage is designed for precise sample placement, with full stage centering and a dual-axis mechanical caliper which can accommodate varying specimen sizes. Once centered, the specimen can be rotated to locate its axis and tested for birefringence. The sub-stage polarizer can also be rotated to avoid stage movement when working with specimens with weaker birefringence.

    Koehler Transmitted Illumination

    Built on Koehler illumination principals, the sub-stage lighting provides evenly-distributed light for optimal contrast. The rear-mounted 100W incandescent light-source provides 100 CRI illumination with ample brightness for contrast-enhancement methods like darkfield. The lower color temperature of the halogen light-source causes less eyestrain compared to high-Kelvin LED. The light condenser uses a swing mechanism for optimized lighting at both high and low magnifications, with a NA0.25 setting for full coverage at extremely low magnifications. An iris diaphragm allows you to adjust the aperture to optimize contrast and depth-of-field. The condenser holder has an integrated, rotatable polarizer for diascopic polarization. It uses rack-and-pinion height adjustment for precision control, and is centerable for proper alignment. The condenser is top-mounted for easier replacement when working with additional condensers. The illuminator's field lens provides an iris diaphragm to control light-spread, optimizing contrast and definition in specimen features.

    Koehler Reflected Illumination

    The top illuminator also uses a 100W incandescent light-source to provide ample light for use with polarization. Adjustable aperture and field diaphragms offer precise control over the light field for improved contrast and edge sharpness. A removable polarizer board provides polarization for reflected illumination. The analyzer is equipped with a dial to control the angle of cross-polarization.

    Digital Imaging

    Monitor and capture photos and videos with the included 6.3MP USB3.0 camera. The highly-sensitive back-illuminated sensor is designed for improved low-light imaging, making it suitable for fluorescence and darkfield microscopy. A 0.5X reduction lens is included for use with 23mm-30.5mm ports 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.

It uses rack-and-pinion height adjustment for precision control, and is centerable for proper alignment. The condenser is top-mounted for easier replacement when working with additional condensers. The illuminator's field lens provides an iris diaphragm to control light-spread, optimizing contrast and definition in specimen features.

    Koehler Reflected Illumination

    The top illuminator also uses a 100W incandescent light-source to provide ample light for use with polarization. Adjustable aperture and field diaphragms offer precise control over the light field for improved contrast and edge sharpness. A removable polarizer board provides polarization for reflected illumination. The analyzer is equipped with a dial to control the angle of cross-polarization.

  • The PZ620T is an indispensable instrument for mineralogists, pathologists, and any laboratory that needs a polarizing microscope that delivers on quality and versatility. The microscope is equipped to handle polarization for transmitted and reflected illumination, with a rotating stage and Bertrand lens for in-depth mineral analysis. High-power incandescent illumination and strain-free optics ensure optimal image quality for both orthoscopic and conoscopic observation over a large magnification range with seven included objective lenses.

    Viewing Head

    The microscope's head is designed for precision and comfort. The super-widefield optics provide a larger field-of-view so you can see more specimen at any magnification. Compensation-free Siedentopf interpupillary adjustment allows any user to properly align the oculars without readjusting focus. For users with astigmatism or asymmetrical vision, the left ocular can be adjusted to fine-tune focus. The photo port is equipped with a 23mm tube for attaching cameras with compensating lenses, and is height-adjustable to match focus with the eyepieces. The port is compatible with our YX series C-mount adapters which can attach directly to C-mount cameras without a compensating lens – ideal for 1” format sensors. The head is set to a 30° incline which is ideal for viewing from a standing position, and it can be rotated 360°.

    Betrand Lens

    The Bertand lens allows the user to quickly switch between normal orthoscopic and conoscopic observation. This is required to shift to the rear focal plane for proper alignment of the aperture diaphragm, and to observe interference patterns created by minerals under polarized light. The lens assembly has a slot for the included first-order, quarter-wave, and quartz-wedge retardation plates.

    Optics

    The infinity-corrected optical system eliminates optical errors when using filters and other in-line components, which is of paramount importance in polarized-light microscopy. The quintuple objective turret provides instant access to 5 magnification levels to efficiently move through magnifications from 50X to 1000X. Seven objective lenses are provided ranging from 5X to 100X, with both oil and dry 100X lenses. Additional 15X eyepieces expand the magnification range up to 1500X with 12 possible unique combinations. The turret's reversed orientation provides more working room above the stage. These high-quality lenses are strain-free to ensure accurate observation under polarized light, with plan-achromatic corrections to improve resolution and field flatness for edge-to-edge sharpness. Each objective mount can be independently centered to ensure proper alignment.

    The Stage

    The stage is designed for precise sample placement, with full stage centering and a dual-axis mechanical caliper which can accommodate varying specimen sizes. Once centered, the specimen can be rotated to locate its axis and tested for birefringence. The sub-stage polarizer can also be rotated to avoid stage movement when working with specimens with weaker birefringence.

    Koehler Transmitted Illumination

    Built on Koehler illumination principals, the sub-stage lighting provides evenly-distributed light for optimal contrast. The rear-mounted 100W incandescent light-source provides 100 CRI illumination with ample brightness for contrast-enhancement methods like darkfield. The lower color temperature of the halogen light-source causes less eyestrain compared to high-Kelvin LED. The light condenser uses a swing mechanism for optimized lighting at both high and low magnifications, with a NA0.25 setting for full coverage at extremely low magnifications. An iris diaphragm allows you to adjust the aperture to optimize contrast and depth-of-field. The condenser holder has an integrated, rotatable polarizer for diascopic polarization. It uses rack-and-pinion height adjustment for precision control, and is centerable for proper alignment. The condenser is top-mounted for easier replacement when working with additional condensers.

Adjustable aperture and field diaphragms offer precise control over the light field for improved contrast and edge sharpness. A removable polarizer board provides polarization for reflected illumination. The analyzer is equipped with a dial to control the angle of cross-polarization.

    Digital Imaging

    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 for use with 23mm-30.5mm ports 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.
