This is a top-class trinocular 10X-30X stereo microscope. It incorporates all the most excellent features of a high quality laboratory instrument. Designed to meet the demands of modern professional microscopy applications this microscope exceeds all expectations. The trinocular port enables to add photographic or video capability. The versatile illumination system with the microscope provides both incident (top) lighting and transmitted (bottom) lighting with intensity controls. The top lighting shining down onto objects is used for the observation of surface details and fine structures of three-dimensional objects. The transmitted illumination through the frosted stage plate is for the observation of the objects that allows light to get through them like slides diamond and etc. This microscope provides super widefield optics high resolution and good depth within a broad field of view. With super widefield eyepieces it provides crystal clear images and large working distance. The 45 degree inclined trinocular and high-eyepoint design ensures an easy observation especially for eyeglass wearers. The rubber eyeguards provide further comfort. This microscope is an ideal instrument for gemologists jewelry dealers and collectors.
