Lens Germanium (Ge lens) ee Codsiyada Infrared

Lens Germanium waa muraayad indhaha laga sameeyay germanium.Germanium (Ge) waa walxo crystalline ah oo leh index ugu sarreeya (4.002@11µm) ee agabka infrared-ka ee inta badan la isticmaalo.Waxa kale oo ay leedahay kala firdhis hooseeya marka la barbardhigo, engegnaanta sare iyo cufnaanta.Iyada oo ay ugu wacan tahay baaxaddeeda gudbinta ballaaran (in ka badan 45% ee band 2-12 micron) iyo mugdiga UV iyo iftiinka muuqda, Germanium waxay si fiican ugu habboon tahay codsiga IR sida nidaamyada sawirka kuleylka, codsiyada beerta infrared iyo qalabka falanqaynta saxda ah.

Germanium sidoo kale waxay ku xiran tahay ka cararka kulaylka.Marka heerkulku sii kordho, nuugista ayaa si degdeg ah u kordheysa.Saamayntan kulaylka ah awgeed, muraayadda germanium kuma habboona in lagu isticmaalo heerkul ka sarreeya 100°C.

Wavelength Infrared wuxuu soo saari karaa noocyo kala duwan oo lens germanium ah oo leh diyaarad, concave, convex, aspheric iyo sagxadaha kala duwan.Germanium wuxuu caan ku yahay nidaamyada ka shaqeeya 3-5 ama 8-12µm spectral gobolka, oo leh dahaar-ka-hortagga milicsiga (daahan AR), celceliska gudbinta waxaa la keeni karaa ilaa 97.5-98.5% waxay kuxirantahay baaxadda dahaarka.Waxaan sidoo kale codsan karnaa daahan dheeman-u eg oo kaarboon ah (daahan DLC) ama daahan sare oo waara (daahan HD) dusha muraayadda si aan u bixinno difaac dheeraad ah oo ka dhan ah xoqidda iyo saameynta.

Wavelength infrared waxay soo saartaa muraayadaha germanium oo tayo leh.Waxay diiradda saari karaan ama kala duwanaan karaan iftiinka soo socda si ay u buuxiyaan shuruudaha gaarka ah ee nidaamka infrared.Codsigu wuxuu noqon karaa sawirka kulaylka, heerkulbeegyada, isku-dhafka iftiinka, falanqaynta spectrum iyo iwm.
