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 baka ho kheloha ho honyenyane, boholo ba matheba le liphoso tse ka pele tse bapisoang le lilense tse entsoeng ka lisebelisoa tse ling.
Paralight Optics e fana ka Zinc Selenide (ZnSe) Positive Meniscus Lenses tse fumanehang ka sekontiri sa Broadband AR se ntlafalitsoeng bakeng sa 8 µm ho isa ho 12 μm spectral range e 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.
