This is a trinocular stereo microscope with a 144-LED compact ring light and an 8MP USB digital camera. The microscope has a super widefield optical system that provides a very large zoom magnification power (52:1) which offers 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 has a compact design with a built-in dimmer providing cool even and bright LED illumination. 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. It is OEM d by the same technicians and on the same production line that makes optical instruments for Leica Zeiss Nikon and Olympus. This microscope is in a factory sealed box with a retail value over $2 500.
