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

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

  • 9MP (3488x2616 pixels) color digital camera with 0.5X reduction lens and 0.01mm calibration slide
  • Advanced oil darkfield NA 1.36-1.25 and brightfield Abbe NA 1.25 condensers included
  • Large double layer mechanical stage and sturdy metal framework
  • Replaceable 3W LED transmitted light with adjustable intensity
  • Coaxial coarse and fine focus knobs on both sides with tension control

The M837L series compound microscope is a class leader offering professional features at an affordable price. This darkfield version provides an additional observation method to enhance contrast when viewing certain low-contrast specimens including unstained live cells. Along with the microscope's standard condenser and objective lenses used for brightfield observation, a specialized darkfield condenser and 100X variable-aperture lens are included.

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.

Optics

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
100X plan-achromatic, iris 0.31-1.25 oil 0.17mm

Specimen Stage

The 2-layer mechanical stage provides smooth and precise movement for the 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 stage’s height 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.

Darkfield Observation

An oil darkfield condenser and a specialized 100X darkfield objective lens are included for darkfield observation. The condenser is designed for use with immersion oil and can accommodate higher numerical-aperture lenses. Two centering screws allow you to properly center the condenser for optimal contrast. The 100X plan-achromatic lens has a built-in iris to adjust its numerical aperture for fine-tuning contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in the refractive index. This is particularly useful for observing live cells including blood analysis.

Digital Imaging

The included 9MP camera and software allow you to preview and record photos and videos on your computer. The camera attaches to your computer using a simple USB 2.0 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.
