GLIS-3000 GEM Luminescence Imaging System can help the user to judge batches of small diamonds quickly (as small as 0.001 carat) and mounted diamond. The Ultraviolet fluorescence image and the phosphorescence image of natural diamond and synthetic diamond are different. GLIS-3000 excites diamond to becomes luminescence through the built in Ultraviolet light source, captures and records the fluorescence and phosphorescence image of the sample, and we can find out the position of the suspected diamonds with problem by analyzing the relevant images.





Imaging analysis



The fluorescence and phosphorescence of diamond

When exposed to UV light, diamond can emit different intensity of the blue visible light, which is fluorescence. If we remove the UV light source, diamond can still emit visible light, this is phosphorescence.
