This is a great turnkey package for a simul-focal stereo microscope with an articulating pillar arm and a 5MP digital camera. It includes a 3.5X-225X simul-focal trinocular zoom microscope, an articulating pillar arm, a 144-LED ring light and a 5MP USB digital camera. This microscope features a unique simul-focal optical system with an adjustable trinocular port to enable well-focused clear images on your computer/video screen while simultaneously obtaining sharp, focused images through the eyepieces. Offering sharp and crystal clear images, this unit is a perfect stereo microscopy system for multiple applications. With 30mm super widefield, high-eyepoint optics, it provides a very large zoom magnification range (26:1) and a large working distance (8", 200mm). With a vertical pillar and a clamp, the articulating arm provides great flexibility. The LED ring light provides bright, even and cool 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 great for both industrial and biological applications. It is an ideal instrument for manufacturing engineers, researchers, gemologists, lab technicians, and anyone in electronics and semiconductor industries. This microscope is made by the same technicians and on the same production line as optical instruments for Leica, Zeiss, Nikon and Olympus. It comes brand new in factory sealed box with a retail value of $3,400.
