This is a 3.5X-90X zoom stereo trinocular microscope. This trinocular microscopy comes with super widefield optics, 9.0MP USB digital imaging system and versatile illumination system that provides both incident (top) and transmitted (bottom) lights. The incident light is used for the observation of three-dimensional objects due to shining down onto the objects. The transmitted light is used for the inspection of the objects that allow light to get through them like diamonds. With the 0.5X barlow lens, the working distance can be as long as 6-1/2" (165mm), and the field of view can be as large as 2-3/8" (60mm) in diameters. The 3488x2616 pixels USB digital imaging system captures still microscope images and live video on computer. The included software compatible with Windows 2000/XP/Vista/Windows 7 can also be used to make measurements. The stereo microscope is useful for many applications (biological research laboratories, engravers, watchmakers, gemologists, collectors, jewelers and anyone in electronic industry).
