Stereo gemstone microscope

The KSW6000 is a gemmological Stereo microscope for the investigation of gemstones, precious stones and minerals. With an infinitely variable zoom in the range 0.7X – 4.5X., magnifications of up to 45x are possible. The microscope body can be tilted up to 38° and rotated up to 325°, ensuring customised alignment. The device is equipped with transmitted light and dark-field illumination, LED gooseneck illumination and a fluorescent lamp, which can be activated individually or in combination. As a trinocular microscope, a microscope camera can easily be connected for crystal-clear photos or videos.
