This trinocular stereo microscope comes with a 144-LED 4-light-zone ring light and a 1.3MP USB digital camera. The microscope has a super widefield optical system that provides a large zoom magnification power (26:1) and a large working distance (8 200mm). The trinocular port uses the third port for camera capabilities or a third party to view as well giving you the remaining two ports to view your specimen. The 144-LED ring light is lighting-direction changeable and lighting-intensity adjustable providing cool even and bright LED illumination. It features a separate control box allowing you to turn on/off each portion of the 4 light zones individually as well as changing the lighting direction so you may obtain the best images for your stereo microscope. 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 manufacturing engineers lab technicians gemologists circuit board inspectors and anyone in electronic and semiconductor industries. It is also the right microscope for biological laboratory applications that require low heat release. This microscope is in a factory sealed box with a retail value over $2 200.
