About this product

Key Features

40X to 2500X expanded magnification range using high-quality, color-coded objective lenses, and 10X and 25X eyepieces for six unique settings ideal for viewing cellular structures and microorganisms.
The trinocular viewing head uses sliding interpupillary adjustment, and offers a dedicated phot port
Two-layer mechanical stage with caliper and coaxial X-Y controls, and symmetrical coarse and fine focus knobs provide precision adjustments with an ergonomic design for an efficient workflow
Built-in illumination uses an energy-efficient LED with brightness control, and an Abbe condenser with an iris diaphragm to improve contrast and depth
View live images and capture photos and videos with the included 18MP USB 3.0 camera. Included software for Windows, Mac, and Linux provide tools for image processing, measuring, and more.

The M837L series compound microscope is a class leader offering professional features at an affordable price. The trinocular viewing head is customizable and is equipped with a dedicated photo port which works simultaneously with both eyepieces. Precision mechanics provide optimal control over stage movements and focusing. The microscope is equipped with LED-based brightfield illumination, and supports optional accessories for various contrast-enhancing techniques such as darkfield and phase-contrast. Its time-tested design and upgradability have made it a favorite among lab technicians, veterinarians, and teachers.

Viewing Head

The trinocular viewing head has a comfortable 45° incline for viewing while seated or standing, and can be swiveled 360°. Ocular spacing can be easily customized using sliding interpupillary adjustment. Dual diopters allow both eyepieces to be focused independently. The trinocular photo-port adds a dedicated mounting tube for cameras. The 23mm tube is height-adjustable to fine-tune the focus to match the eyepieces. Its simul-focal design allows simultaneous use with both eyepieces so no switching is necessary.


The microscope is equipped with four objective lenses mounted on a rotating turret to quickly move through the various magnifications. The lenses use DIN international standards, and are achromatically corrected to improve clarity and color accuracy. They provide a magnification range from 10X to 1000X when used with the standard 10X eyepieces, ideal for viewing a wide range of specimens including cellular structures and bacteria. Additional 25X eyepieces are included to expand the maximum magnification to 2500X with 6 unique levels.

Objective Lenses

Magnification Corrections NA Immersion Medium Cover-glass Thickness
4X achromatic 0.10 0.17mm
10X achromatic 0.25 0.17mm
40X achromatic 0.65 0.17mm
100X achromatic 1.25 oil 0.17mm

Specimen Stage

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. A convenient lever grouped with the left-side focus knobs can be used to lock and unlock the coarse focus adjustment to prevent damage to the lenses and specimen.

LED Illumination

The LED sub-stage lighting provides cool, energy-efficient illumination. The light-source is daylight balanced to produce natural colors. 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 height adjustment for precision control.

A sub-stage mirror is included as an alternate light source when electricity is not available. The mirror can be mounted on top of the illuminator’s field lens to direct ambient light into the condenser.

Digital Imaging

The included 18MP camera and software allow you to preview and record photos and videos on your computer. The camera attaches to your computer using a high-speed USB 3.0 connection. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, and a full complement of measuring tools. Cutting-edge features such as real-time auto-stitching and focus-stacking add new dimensions to imaging. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.
