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

  • 3.5X-90X extended zoom magnification using high-quality Greenough stereoscopic objective lenses with 0.5X and 2X Barlow lenses.
  • Includes a specialized condenser plate for transmitted darkfield illumination -- perfect for gemology
  • Super widefield optical system offering crystal clear images
  • Top and bottom lights with separate dimmers
  • Heavy-duty sturdy pillar stand with metal framework
  • Trinocular port for adding photo or video capability

This first-class trinocular darkfield stereo zoom microscope incorporates all the most excellent features of a high quality laboratory instrument. Designed to meet the demands of modern gemology microscopy, this microscope exceeds all expectations. It comes with super widefield optics, gem clamp, and darkfield condenser with iris diaphragm. The brightfield and darkfield illumination system provides both incident (top) lighting and transmitted (bottom) lighting. The top lighting shining down onto objects is used for the observation of surface details and fine structures of jewels or gemstones. The transmitted illumination through the condenser is for the examination of inside quality of diamonds.

Optics

The stereo optics provide clear, sharp images with excellent focus-depth and a large working-distance. With 0.7X-4.5X zoom objectives, moving through the magnification range is as easy as turning a knob. 10X wide-field eyepieces provide an ample magnification range from 7X to 45X, with high-eyepoint optics to accommodate glasses or goggles. 0.5X and 2X Barlow lenses are included, which can be alternated to either halve or double the magnification range, expanding the possible magnifications to 3.5X-90X.
