Tlhaloso e Khutšoanyane:

Li-prism tsa quartz tse kopantsoeng ke likarolo tsa bohlokoa tsa optical tse sebelisetsoang ho laola, ho laola, le ho tsamaisa leseli ka mefuta e mengata ea lisebelisoa tsa optical tse sebetsang hantle. Li entsoe ka silica e kopantsoeng ea "ultra-high pure purity fused", li-prism tsena li fana ka lisebelisoa tse ikhethang tsa phetisetso ho pholletsa le mahlaseli a kotsi a ultraviolet (UV), a bonahalang, le a haufi le infrared (NIR) spectral ranges. Ka khanyetso e ikhethang ea mocheso le lik'hemik'hale, matla a matla a mochini, le li-birefringence tse nyane, liprism tsa quartz tse kopaneng li loketse lits'ebetso tsa bohlokoa ho spectroscopy, laser optics, imaging le lisebelisoa tsa mahlale.
