The ME520T is a highly versatile microscope for materials inspection using transmitted and reflected light. Primarily designed as an upright metallurgical microscope, the high-power 100W epi-illumination system can be used for brightfield, darkfield, and basic polarized-light. Wafer inspection and metallographic applications will greatly benefit from the illumination modes. The addition of transmitted lighting provides even more flexibility for biological specimens, or backlighting hollow or porous materials. This instrument will be indispensable in any biology, medical, or materials lab.

Monitor and capture photos and videos with the included 3.0MP USB3.0 camera. The C-mount camera is specially designed for use with microscopes, allowing you to watch live images, and to record photos or videos on your computer. This ability to view microscopic images on your computer reduces eye-strain, and allows groups of people to view images at the same time. The USB 3.0 connection provides greater bandwidth for faster frame-rates. A 0.37X reduction lens is included for use with 23mm-30.5mm ports to capture more of the microscope's field-of-view. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.
