This 7X-100X trinocular jewelry/gem stereo zoom microscope comes with a trinocular zoom head with a photo port, a darkfield condenser, a jewelry/gem clamp, a gooseneck fluorescent spot lights, and transmitted (bottom) LED illumination system. The trinocular port enables to add photographic or video capability. The lighting Guides shining down onto objects is used for the observation of surface details and fine structures of jewels or gemstones. The transmitted illumination through the condenser is for the examination of inside quality of diamonds. The 39 degree inclined trinocular ensures an comfortable observation. This microscope gives crystal clear images. It provides large zoom magnification range (7:1) and large working distance. It is an ideal instrument for gemologists, jewelry dealers and collectors.
