SELECTING A COMPOUND MICROSCOPE is as easy as 1-2-3...

Select the type of microscope you need or your industry

Select by type of microscope - Our Compound Microscope Assortment has been divided into major categories to make your shopping easy.

These categories include:

Brightfield, Darkfield, Phase-Contrast, Inverted and others

Choose a business application or industry to find the right compound microscope. Major industries or applicatins include:

Veterinary, Laboratory Use, Teaching, Metallurgical, Gemology and many others

Select a Magnification

AmScope offers an industry-leading selection of magnifications. All products are in-stock and usually ship the same day ordered

Select a Camera

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

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.

Key Features

  • 6.7X-90X extended zoom magnification using high-resolution Greenough stereoscopic objective lenses and a 2X Barlow lens.
  • High-resolution ZM series optics provide improved sharpness with lower distortion
  • A highly-versatile stereo microscope on a heavy-duty, multi-pivot boom-stand which allows the microscope to easily swing into place when needed, and away when not.
  • The stereo optics provide upright images with clear depth-of-field and a wide view for hands-on applications.
  • This microscope is ideal for laboratories, repair shops, and engravers.

The ZM-4BN matches its sleek design and high-resolution optics with a brawny boom-stand for demanding biological and industrial applications. The ZM series shows improvements in resolution, contrast, and distortion compared to our staple SM series. This model is especially popular in the QC, repair and engraving industries thanks to its ease-of-use and reliability. With its wide zoom range and double-arm boom-stand, this model will become an indispensable instrument in any workshop or lab.


Optics

The advanced optical system in the ZM series microscope produces higher resolutions throughout its zoom range, with stunning contrast and color accuracy. The 0.67X-4.5X objective lenses offer excellent focus-depth and a large working-distance, with symmetrical zoom knobs to easily move through magnifications. 10X wide-field eyepieces provide an ample magnification range from 6.7X to 45X, with high-eyepoint optics to accommodate glasses or goggles. A 2X Barlow lens is included, which can be mounted to the objective housing to double the magnification range to 13.4X-90X. This will also result in decreased working distance. The combined magnifications extend the range to 6.7X-90X.

Ocular Adjustment

This model does not have integrated ocular diopters, opting for focusable eyepieces instead. This helps maintain consistent focus when dioptric adjustments are not needed. Locking screws on each ocular tube will prevent rotation when adjusting focusable eyepieces, and stop eyepieces from falling out. Sliding interpupillary adjusters ensure that each user can properly align the eyepieces for comfortable viewing.


Double-arm Boom-Stand

The multi-pivoting, double-arm stand provides a stable, flexible support system, ideal for hands-on work. Use of a drop-down column allows the head to be positioned at virtually any angle. Ball-bearings provide smooth movement of the lateral arms, which can easily pivot the microscope out of the way when it is not needed. The heavy, steel base ensures the stability of the microscope, even when laden with attachments.
