Made in Germany. The Eickhorst desktop UV lamp is used for testing the fluorescence of diamonds and gemstones with long-wave 366nm UV lamps. The high intensity of the powerful UV lamps also shows weak fluorescence as the test stone is placed on the UV filter. The viewing cabinet blocks surrounding light from the specimen being tested and allows UV testing with the room lights on. Due to the viewing angle and the black surface of the “black light” UV filter, there is no misinterpretation by the viewer due to the bluish residual light of the visible UV component.
