Zinc Selenide (ZnSe)
Lilense tse ntle tsa Meniscus
Lilense tsa ZnSe li loketse haholo ho sebelisoa ka li-lasers tsa CO2 tse matla haholo.Ka lebaka la index ea holimo ea ZnSe, re ka fana ka sebopeho se chitja se setle ka ho fetesisa bakeng sa ZnSe, e leng moralo o motle oa meniscus.Lilense tsena li etsa hore ho be le mekhelo e nyane, boholo ba matheba le liphoso tse ka bapisoang le lilense tse entsoeng ka lisebelisoa tse ling.
Paralight Optics e fana ka Lilense tsa Zinc Selenide (ZnSe) Positive Meniscus tse fumanehang ka sekoaelo se sephara sa AR se lokiselitsoeng sebaka sa 8 µm ho isa ho 12 μm se kentsoeng libakeng tseo ka bobeli.Koko ena e fokotsa haholo ponahalo e phahameng ea bokaholimo, e fana ka phetisetso e fetang 97% holim'a mefuta eohle ea liphahlo tsa AR.
