Zinc Selenide (ZnSe)
Lenses Meniscus togan

Muraayadaha 'Meniscus lenses' ayaa ugu horrayn loo isticmaalaa in diiradda lagu saaro cabbirrada dhibcaha yar yar ama codsiyada isku-dhafka.Waxay bixiyaan waxqabad aad u sarreeya iyagoo si weyn u yareynaya aberrations wareega.lenses togan (convex-concave) lenses, kuwaas oo ka kooban dusha convex iyo dusha concave oo ka dhumuc weyn dhexda marka loo eego cidhifyada & sababa falaadhaha iftiinka inay isku yimaadaan, ayaa loogu talagalay inay yareeyaan aberration spherical ee hababka indhaha.Marka loo isticmaalo in diirada la saaro laydhka isku dhafan, dhinaca isku dhafan ee lensku waa inuu wajaho isha si loo yareeyo khalkhalka wareega.Marka lagu daro lens kale, muraayad meniscus togan ayaa soo gaabin doonta dhererka xudunta waxayna kordhin doontaa daloolka nambarada (NA) ee nidaamka iyada oo aan la soo bandhigin aberration spherical weyn.Maaddaama muraayadda meniscus-ka togan ay leedahay radius weyn oo qalooc ah oo ku yaal dhinaca koodhka ee muraayadda marka loo eego dhinaca convex-ka, sawirro dhab ah ayaa la samayn karaa.

Muraayadaha ZnSe waxay si gaar ah ugu habboon yihiin isticmaalka leysarka CO2 ee awoodda sare leh.Iyadoo ay ugu wacan tahay tusmada dib-u-celinta sare ee ZnSe, waxaan ku siin karnaa qaabka ugu fiican ee qaabaynta qaabka ZnSe, kaas oo ah naqshadda meniscus-ka togan.Muraayadahani waxa ay dhaliyaan khalkhal yar yar, cabbirka dhibcaha, iyo khaladaadka hore ee mowjadaha oo u dhigma muraayadaha qaabka ugu wanaagsan ee ay alaabta kale sameeyeen.

Paralight Optics waxay bixisaa Zinc Selenide (ZnSe) Lenses Meniscus togan oo la heli karo daahan AR ballaaran oo loo habeeyay 8 µm ilaa 12 μm kala duwanaansho muuqaal ah oo lagu kaydiyay labada dusha sare.Dahaarkani wuxuu si weyn u yareynayaa milicsiga sare ee substrate-ka, taasoo keenaysa gudbin celcelis ka badan 97% dhammaan noocyada daahan AR.

Tilmaamaha Guud:

pro-xiriirka-ico — Tixraaca Sawirka

Lens Meniscus togan

f: Focal Length
f_bLength Focal Back
R: Radius of Curvature
t_c: Dhumucda dhexe
