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

  • 40X to 2000X achromatically-corrected magnification for studying a range of specimens including hair follicles, cells, and bacteria. 10X and 20X eyepieces provide 8 unique magnification settings.
  • An economical microscope for students and professionals, the T120 packs high-quality optics and refined mechanics into a compact form.
  • Professional features include a Siedentopf triinocular head for precise adjustments, a 2-layer mechanical stage with low-position controls, and coaxial coarse and fine focus for ergonomics and an efficient workflow.
  • The trinocular photo port can be used to mount a camera without interfering with the eyepieces.
  • Includes The World of the Microscope: a beautifully-illustrated book that will help guide first-time users through the history of microscopes and how to perform experiments right at home.

The T120 trinocular compound microscope is designed for teaching demonstrations, clinical examinations and laboratory applications. It is an ideal microscope for teachers and students, including those in medical school or with a major in biology. It has a number of advancements in functionality compared to other microscopes in its class, such as enhanced LED lighting, centerable condenser, and Siedentopf head adjustments. Use the microscope for studying fixed or live cells, bacteria, plants and soil, or water samples.

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 the left ocular tube to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain. Various eyepieces can be used to increase the overall optical magnification. 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.

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 LED sub-stage lighting provides cool, energy-efficient illumination. The light-source is daylight balanced to produce natural colors for imaging. With our specially developed fly-eye lens, the light is evenly distributed at maximum brightness to improve contrast and resolution. Illumination is further enhanced by a centerable Abbe condenser, which can be realigned for any magnification to guarantee proper lighting.

This kit includes a beautifully-illustrated book that will help guide first-time users through the history of microscopes, and how to perform some experiments right at home. The book provides an insight into the history of microscopic study and the invention of microscopes. Several popular experiments are illustrated and explained to guide you through the scientific process.
