Kutheni ukhetha ifestile yegermanium yethemometha ye-infrared
Ngokubanzi, iglasi yegermanium isetyenziswa njengefestile ye-infrared thermal imager ukukhusela inkqubo yamehlo elandelayo kunye ne-infrared detector.Nangona kunjalo, ngenxa yokuba i-refractive index ye-germanium material yi-4, ukusetyenziswa ngokuthe ngqo kuya kubangela ukulahlekelwa okukhulu kwesignali yesiganeko.Ukuze kuphuculwe amandla okuhambisa umqondiso we-infrared, iglasi ye-germanium kufuneka ifakwe iifilimu ezifanelekileyo ukuphucula ukuhanjiswa kunye nokukhusela umphezulu we-germanium lens.
Iglasi yeGermaninium elaminethiweyo inokuhanjiswa kokukhanya okuhle kakhulu kwi-2-16um, kwaye iimpawu zayo ezibonakalayo zizinzile.Akulula ukubonakalisa nge-hydroxide, igesi ye-asidi kunye namanzi.Ithemometha ye-infrared kunye nomfanekiso oshushu kufuneka zixhotyiswe ngesihluzo esiphakathi nesikude se-infrared.Ithemomitha ye-infrared kunye nomfanekiso oshushu zisebenza ngokubanzi kwibhendi ye-2-13um, ngelixa iglasi ye-germanium elaminethiweyo inokuhambisa kakuhle kakhulu kwi-infrared ekude.Ukuhanjiswa kweelensi eziqhelekileyo zokukhanya kweli bhanti kuphantsi kakhulu, ngoko ke akunakugqitywa
Ukongeza, ifilimu ye-optical efakwe kwiglasi ye-germanium elaminethiweyo inokwandisa kakhulu ukuhanjiswa kwayo kunye nokunciphisa ukuhanjiswa kwendawo yeglasi ye-germanium elaminethiweyo.Iglasi ye-laminated yaseJalimane ayidluli kwibhendi yokukhanya engabonakaliyo.Kweminye imifanekiso eshushu, abantu banokusebenzisa iikristale zesilicon ukuze bathathe indawo yegilasi elaminethiweyo yegermanium.Ibhendi yamaza yeekristale zesilicon ayikho kude kwiglasi yegermanium elaminethiweyo.
Isilicon (Si) i-polycrystalline silicon yi-organic chemical yeplastiki imathiriyeli ekrwada enamandla amakhulu kunye namanzi anganyibilikiyo.Ikuluhlu lwe-1-7 μ M-band inokuhanjiswa kokukhanya okuhle kakhulu.Ukongeza, ikwibhendi ekude ye-infrared 300-300 μ M nayo ine-transmittance yokukhanya elunge kakhulu, nto leyo ebonisa ukuba ezinye izinto ezibonakalayo kunye ne-infrared azinayo.
Isilicon (Si) i-polycrystalline silicon isetyenziswa ngokubanzi kwi-3-5 μ Ngenxa yokusebenza kwayo kakuhle kokufudumeza ubushushu kunye nokuxinana kwesalamane esisezantsi, ikwayinto eqhelekileyo yokwenza iilensi ezikhanyayo, iithemometha ze-infrared kunye nelensi ye-infrared optical laser.
Iglasi yeGermanium isetyenziswa kwifestile ye-infrared thermal imager kunye nethemometha ye-infrared.Ibhendi ye-8-14um iqwalaselwa ngokukodwa.Ukuhanjiswa kweglasi ye-germanium ngaphandle kokugquma yi-40-50% kuphela, ngelixa ukuhanjiswa kweglasi ye-germanium egqunywe ngefilimu ye-anti reflection inokufikelela kuma-90%.Ukongeza, uninzi lwabathengi bafuna ifilimu ye-DLC yedayimane efana nekhabhoni kwiglasi yegermanium ukomeleza ubulukhuni beglasi yegermanium kunye nokufezekisa isiphumo esithile sobungqina bokudubula.
