Zinc Selenide (ZnSe)
Muraayadaha Bi-Concave

Muraayadaha laba-kooxeed ama Double-concave (DCV) waxay leeyihiin dherer aan fiicneyn.Muraayadahan kala duwan ayaa loo istcimaali karaa in lagu kala saaro laydhka isku xidhan ee diirada la saaray waxaana caadi ahaan loo adeegsadaa balaadhinta laydhka nooca Galilean.Waxa kale oo inta badan loo isticmaalaa in lagu kala tago ama la kordhiyo kala duwanaanshaha laydhka isku xidha.Nidaamyada indhaha, waa wax caadi ah in cilmi-baarayaashu ay si taxadar leh u doortaan indho-indheynta si ay u-horjeedka ay keeneen muraayadaha-toossan-iyo-negative-focal-length lenses-ku-dhawaad ​​baabi'iyaan.Kuwo kale waxay u isticmaalaan muraayadahan laba-labo si ay u kordhiyaan dhererka fogaanta wax ku oolka ah ee muraayadaha isku-xidha sida muraayadaha meniscus-ka xun.

Marka la go'aaminayo inta u dhaxaysa lens-concave lens iyo lens bi-concave ah, oo labaduba ay sababaan iftiinka dhacdada si uu u kala duwanaado, inta badan way ku habboon tahay in la doorto muraayad laba-kooxeed haddii saamiga isku-xidhka saxda ah (masaafada shayga loo qaybiyay masaafada sawirka) waxay ku dhowdahay 1. Marka weyneynta buuxda ee la rabo uu ka yar yahay 0.2 ama ka weyn 5, u janjeera waa in la doorto lens-concave ah beddelkeeda.

Muraayadaha ZnSe waxay si gaar ah ugu habboon yihiin isticmaalka leysarka CO2 ee awoodda sare leh.Paralight Optics waxay bixisaa Zinc Selenide (ZnSe) Bi-Concave ama Double-Concave (DCV) muraayadaha la heli karo oo leh daahan ballaaran ee AR oo loogu talagalay 8 - 12 μm kala duwanaanta muuqaalka ee lagu kaydiyay labada dusha.Dahaarkani wuxuu si weyn u yareynayaa milicsiga sare ee substrate-ka, taasoo keenaysa gudbin celcelis ka badan 97% dhammaan noocyada daahan AR.Macluumaad dheeraad ah oo ku saabsan dahaarka, fadlan ka eeg jaantusyada soo socda tixraacyadaada.
