Cov Khoom Siv Iav Uas Muaj Moulded Infrared Lens Chalcogenide
Cov Khoom Siv Iav Uas Muaj Moulded Infrared Lens Chalcogenide
Cov ntaub ntawv khoom:
Cov iav infrared ib txwm muaj raug sib tsoo, txhuam los yog tig pob zeb diamond los ua nws qhov chaw, hais lwm yam lus: los ntawm "kev tsim khoom txias". Txawm hais tias iav infrared kuj tuaj yeem tsim los ntawm "kev tsim khoom kub", ntawm no peb muaj iav infrared pwm ua los ntawm cov khoom siv iav chalcogenide. Kev pwm iav yog qhov tshwj xeeb rau kev tsim khoom ntau vim tias tus nqi tsim khoom ib lub iav tuaj yeem tswj tau rau qib qis heev. Cov iav pwm kuj muaj cov khoom lag luam zoo hauv kev tsim khoom ntau, uas ua kom ntseeg tau tias cov kab ke infrared muaj kev ntseeg siab zoo.
Cov iav Chalcogenide tsis yog ib qho tab sis yog cov khoom siv amorphous zoo li iav uas kis tau hauv infrared band. Peb tsuas yog xaiv tau cov khoom siv iav chalcogendie hauv infrared lens molding vim lawv cov ntsiab lus yaj qis piv rau lwm cov khoom siv infrared.
Cov iav Chalcogenide muaj qhov kis tau zoo (> 60%) hauv qhov ntau ntawm 2-12 micron, qhov ntsuas qis ntawm kev tawg (2.4-2.8 @ 11 micron), kev hloov pauv thermal qis hauv qhov ntsuas kev tawg thiab kev tawg qis. Lawv muaj cov khoom siv kho tshuab thiab kho qhov muag zoo ib yam li germanium, uas ua rau lawv zoo rau kev siv infrared, tshwj xeeb tshaj yog hauv kev kho xim nrog germanium lens hauv lub kaw lus kho qhov muag.
Tsis zoo li germanium uas yuav tsum tau khawb thiab muaj tsawg, cov khoom siv iav chalcogenide yog cov khoom siv hluavtaws. Lawv cov nqi ruaj khov dua thiab txaus siab. Cov iav ua los ntawm cov iav chalcogenide tuaj yeem hloov cov iav germanium zoo uas lawv yuav ua lub luag haujlwm tseem ceeb dua hauv cov kab ke infrared tshiab.
Cov iav infrared uas muaj qhov ntev ntev tuaj yeem muab cov iav chalcogenide uas ua los ntawm cov pwm nrog cov nplaim aspheric thiab diffractive. Cov iav chalcogenide nrov tshaj plaws rau cov kab ke ua haujlwm hauv 3-5 micron lossis 8-12 micron infrared band, qhov nruab nrab kis tau ntau dua 97.5% nrog cov txheej tiv thaiv kev cuam tshuam (AR txheej). Cov txheej carbon zoo li pob zeb diamond (DLC txheej) lossis cov txheej ruaj khov (HD txheej) kuj tseem tuaj yeem siv rau ntawm cov iav chalcogenide infrared lens kom muab kev tiv thaiv ntxiv tiv thaiv khawb thiab kev cuam tshuam.
Cov Lus Qhia:
Cov duab infrared uas muaj qhov ntev ntawm cov duab infrared no muaj cov iav chalcogenide molded uas muaj qhov loj li ntawm 1-25 hli. Peb cov txheej txheem AR thiab DLC zoo tshaj plaws rau cov kab uas loj li ntawm 3-5 lossis 8-12 micron. Qhov ntev ntawm peb cov duab yuav raug tswj kom txog li +/-1%, qhov tsis sib xws ntawm qhov chaw tsawg dua 0.5 micron, thiab qhov sib txawv ntawm cov duab yuav tsawg dua 1 arc-feeb.
