Zinc Selenide (ZnSe)
Lenses Plano-Concave

Lenses Plano-concave waa muraayado taban kuwaas oo ka dhumuc weyn cidhifka marka loo eego dhexda, marka iftiinku dhex maro iyaga, way kala duwan yihiin oo barta diiradda la saarayaa waa mid muuqaal ah.Dhererkoodu waa taban, iyo sidoo kale radius of curvature ee sagxadaha qaloocan.Marka la eego leexintooda goobeed taban, lenses-concave lenses ayaa la shaqaaleysiin karaa si loo dheellitiro aberrations-ka wareegsan ee ay sababaan muraayadaha kale ee nidaamka indhaha.Lenses-concave lenses ayaa faa'iido u leh kala-duwanaanshaha laydhka isku-dhafka ah iyo isku-dhafka laydhka isku-dhafan, waxaa loo isticmaalaa in lagu ballaariyo iftiinka iftiinka iyo in la kordhiyo dhererka foorarka ee nidaamyada hadda jira.Muraayadahan taban waxaa badanaa lagu isticmaalaa telescopes, kamaradaha, leysarka ama muraayadaha si ay u caawiyaan nidaamyada weyneynta inay noqdaan kuwo is haysta.

Lenses-concave lenses ayaa si fiican u shaqeeya marka shayga iyo sawirku ay ku jiraan saamiyo isku xidhan oo dhammaystiran, oo ka weyn 5:1 ama ka yar 1:5.Xaaladdan oo kale, waxaa suurtogal ah in la yareeyo aberration sppherical, koomada, iyo qallooca.Si la mid ah muraayadaha loo yaqaan 'plano-convex lenses', si loo gaaro waxtarka ugu sarreeya, dusha qalooca waa inuu wajaho masaafada ugu weyn ee shayga ama isku-xidhka aan dhammaadka lahayn si loo yareeyo isbeddelka wareega (marka laga reebo marka loo isticmaalo leysarka tamarta sare leh halkaasoo tani ay tahay in la beddelo si loo baabi'iyo suurtagalnimada muuqaal muuqaal ah. diiradda).

Muraayadaha ZnSe ayaa si gaar ah ugu habboon isticmaalka CO ama CO2 lasers oo awood sare leh.Intaa waxaa dheer, waxay ku siin karaan gudbin ku filan gobolka muuqda si ay u oggolaadaan isticmaalka laydhka toosan ee muuqda, inkastoo dib-u-eegistu ay noqon karto mid aad u cad.Paralight Optics waxay bixisaa Zinc Selenide (ZnSe) Plano-Concave (PCV) muraayadaha la heli karo oo leh daahan ballaaran oo AR ah oo loogu talagalay 2 μm - 13 μm ama 4.5 - 7.5 μm ama 8 - 12 μm kala duwanaansho muuqaal ah oo lagu kaydiyay labada dusha.Dahaarkani wuxuu si weyn u yareynayaa milicsiga sare ee substrate-ka, taasoo keenaysa gudbin celcelis ka badan 92% ama 97% dhammaan noocyada daahan AR.Ka hubi Garaafyada tixraacyadaada.
