Prism ea Quartz e kopantsoeng

Setšoantšo se Hlahisitsoeng sa Fused Quartz Prism

Tlhaloso e Khutšoanyane:

Liprism tsa quartz tse kopantsoeng ke lintho tsa bohlokoa tsa optical tse sebelisetsoang ho laola, ho laola le ho fetisetsa leseli lits'ebetsong tse ngata tsa optical tse sebetsang hantle. Li entsoe ka silica e kopantsoeng e hloekileng haholo, liprism tsena li fana ka thepa e ikhethang ea phetiso ho pholletsa le mefuta ea li-spectral tsa ultraviolet (UV), tse bonahalang, le tse haufi le infrared (NIR). Ka khanyetso e ikhethang ea mocheso le lik'hemik'hale, matla a matle a mechini, le birefringence e fokolang, liprism tsa quartz tse kopantsoeng li loketse lits'ebetso tsa bohlokoa ho spectroscopy, laser optics, litšoantšo le lisebelisoa tsa mahlale.
