Moulded Infrared Lens Chalcogenide iav khoom

Tsob ntoo infrared lo ntsiab muag yog grinded, polished los yog pob zeb diamond tig los ua nws nto, nyob rau hauv lwm yam lus: los ntawm "txias manufacturing".Thaum lub lens infrared tseem tuaj yeem tsim los ntawm "kev tsim hluav taws xob", ntawm no peb tau molded infrared lens ua los ntawm cov khoom siv iav chalcogenide.Lens molding yog tshwj xeeb tshaj yog haum rau ntau qhov ntau lawm vim hais tias tus nqi fabrication ib lub lens yuav raug tswj kom qis heev.Moulded lo ntsiab muag kuj muaj cov khoom zoo sib xws hauv kev tsim khoom loj, uas ua kom muaj kev ntseeg tau zoo ntawm cov tshuab infrared.
Chalcogenide iav tsis yog ib qho tab sis cov iav zoo li amorphous cov ntaub ntawv uas tau xa mus rau hauv cov kab infrared.Peb tsuas tuaj yeem xaiv cov khoom siv iav chalcogendie hauv infrared lens molding vim lawv cov ntsiab lus melting tsawg piv rau lwm cov ntaub ntawv infrared.
Chalcogenide iav muaj qhov sib kis tau zoo (> 60%) nyob rau hauv thaj tsam ntawm 2-12 micron, qhov ntsuas qis ntawm refraction (2.4-2.8 @ 11micron), tsis tshua muaj thermal hloov hauv refractive index thiab tsawg dispersion.Lawv muaj cov khoom zoo sib xws thiab cov khoom siv kho qhov muag rau germanium, uas ua rau lawv zoo haum rau infrared daim ntawv thov, tshwj xeeb tshaj yog nyob rau hauv cov xim kho nrog germanium lens hauv optical system.
Tsis zoo li germanium uas yuav tsum tau mined thiab muaj cov khoom siv tsawg, cov khoom siv iav chalcogenide yog hluavtaws.Lawv cov nqi yog ruaj khov thiab txaus.Lens ua los ntawm chalcogenide iav tuaj yeem ua tau zoo hloov ntawm germanium lo ntsiab muag uas lawv yuav ua lub luag haujlwm tseem ceeb hauv cov qauv tsim tshiab infrared.

Wavelength Infrared tuaj yeem muab molded chalcogenide iav infrared lens nrog aspheric thiab diffractive nto.Chalcogenide iav lo ntsiab muag yog nrov tshaj plaws rau cov tshuab ua haujlwm hauv 3-5 mircron lossis 8-12 micron infrared band, qhov nruab nrab kis tau zoo tshaj 97.5% nrog cov tshuaj tiv thaiv kev cuam tshuam (AR txheej).Pob zeb diamond zoo li cov pa roj carbon txheej (DLC txheej) lossis cov txheej txheem siab ntev (HD txheej) kuj tuaj yeem siv rau ntawm chalcogenide iav infrared lo ntsiab muag los muab kev tiv thaiv ntxiv tiv thaiv khawb thiab cuam tshuam.
