This first-class 3.5X-90X trinocular stereo zoom microscope with 5MP USB digital camera incorporates all the most excellent features of a high quality laboratory instrument. Designed to meet the demands of modern microscopy applications, this scope exceeds all expectations. The microscope comes with SUPER widefield optics and versatile halogen illumination system that provides both incident (top) lighting and transmitted (bottom) illumination. You can choose between incident illumination shining down onto the object or transmitted illumination through the frosted stage plate. The first is used for the observation of three-dimensional objects and the second for the inspection of the objects that allow light to get through them like diamonds.This microscope offers high resolution and good depth within a broad field of view. It provides crystal clear sharp stereo images, 26:1 large zoom magnification range, 8" (200mm) long working distance and 2-1/2" (65mm) super large field of view. Its 45° inclined binocular head ensures an easy observation and rubber eye-guards provide further comfort. The digital camera captures still microscopy images, streams live videos on your computers, and is compatible with Windows XP/Vista/7/8, Mac OS X, and Linux. The 0.5X reduction lens included gives your computer screens the same field of view as your microscope's eyepiece. The user-friendly software for Windows offers advanced features including Stitching, EDF (Extended Depth of Focus), video recording, and measurement functions. Live video and still image capture can be set in different resolutions simultaneously. You can edit and process images in a manner similar to PhotoShop.This microscope system is great for many applications in gemology, geology, forestry, archaeology, agriculture and biology. It is appropriate for educational purposes in hospitals and schools. It is great for the exploration of the world of surface details and fine structures of various materials like wood, metal, solder, semiconductor and gemstone. It is perfect for the examination of insects, plants, rocks, stamps, coins, jewel, soldered points, microelectronic components, circuit boards or virtually any three dimensional objects. This scope is an ideal tool for research labs, gemologists, collectors, engravers, watchmakers, jewelers, dies-makers, philatelists, and anyone in semiconductor or electronic industry.
