AmScope SM-2TZZ 3.5X-180X INSPECTION TRINOCULAR STEREO ZOOM MICROSCOPE
This first-class 3.5X-180X trinocular stereo zoom microscope 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. It comes with SUPER widefield optics and versatile 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, 2-1/2" (65mm) field of view, 52:1 large zoom magnification range, and 8" (200mm) working distance. Its 45 degree inclined trinocular head ensures an easy observation and rubber eye-guards provide further comfort. It is useful for many applications. It can be used 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 electronics industry. It 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. Its retail value is $2,000.
