This trinocular stereo microscope comes with a 1.3MP USB2.0 digital camera and a 4 lighting zone LED ring light. It has a trinocular 3.5X-45X stereo zoom microscope body and a contemporary table stand offering 2-1/2 (65mm) super large field of view 8 (200mm) long working distance and 13:1 large zoom magnification range. The variable 144-LED ring light is lighting-direction changeable and lighting-intensity adjustable providing cool even and bright LED illumination. It comes with a special design with four individual lighting zones that allow you to turn on/off each portion of the light ring separately to change light directions and get the best illumination for your application. The digital camera captures still images and video and allows you to view a live stream on your PC. With software available for Windows Mac and Linux it s a multi-platform imaging solution. The included Windows software offers image-development and measurement tools as well as advanced compositing features such as image-stitching and extended-depth-of-focus. Independent preview and capture resolutions allow you to view high-speed video while capturing high-definition images. For Mac and Linux there is a lite version with limited processing features. This microscopy system is an ideal instrument for gemologists manufacturing engineers and anyone in semiconductor and electronics industries. It is also the right microscope for biological laboratory applications that require low heat release. This microscope comes in factory sealed boxes.
