Zinc Selenide (ZnSe)
Bi-Convex Lenses
Kodayake ruwan tabarau na Bi-convex suna rage raguwa a cikin yanayin da abu da nisan hoto daidai suke ko kusan daidai, lokacin yanke shawara tsakanin ruwan tabarau na bi-convex ko DCX da ruwan tabarau na plano-convex, duka biyun suna haifar da haɗaɗɗun hasken lamarin don haɗuwa, yana da yawanci an fi son zaɓin ruwan tabarau bi-convex don rage ɓarna idan rabon abu da nisan hoto (cikakkiyar rabon haɗin gwiwa) yana tsakanin 5:1 da 1:5. A wajen wannan kewayon, ana fi son ruwan tabarau na plano-convex.
Ruwan tabarau na ZnSe sun dace sosai don amfani tare da manyan laser CO2 masu ƙarfi. Paralight Optics yana ba da ruwan tabarau na Zinc Selenide (ZnSe) Bi-Convex wanda ke samuwa tare da babban shafi na AR wanda aka inganta don kewayon 8 zuwa 12 μm wanda aka ajiye akan duka saman biyu. Wannan shafi yana rage girman girman abin da ke cikin ƙasa, yana samar da matsakaicin watsawa fiye da 97% akan duk kewayon shafi na AR. Bincika Hotuna masu zuwa don bayanin ku.
