Anti-reflective iavyog siv nyob rau hauv ntau yam kev lag luam, nrog rau cov neeg siv khoom siv hluav taws xob, hnub ci vaj huam sib luag, cov khoom siv kho qhov muag, kev tsim kho, thiab tseem tuaj yeem siv los ua kev txuag kos duab. Lub ntsiab feature ntawm AR iav yog tias nws tuaj yeem txo qhov kev xav ntawm lub teeb. Txhawm rau txhim kho qhov pom tseeb thiab zoo ntawm cov duab lossis cov khoom pom lossis pom los ntawm iav. Yuav kom ua tiav cov nyhuv no, peb yuav tsum kho cov iav nto thaum lub sijhawm tsim khoom. Qhov saum npoo ntawm iav yuav tsum tau coated, uas tuaj yeem hloov lub cev lub cev ntawm cov iav. Li no txo lub teeb reflection thiab nce lub teeb transmittance.
Qhov tseem ceeb ntawm kev siv txheej txheej
Daim ntawv thov txheej Cov kauj ruam no yog qhov tseem ceeb rau kev hloov cov iav zoo tib yam rau hauvanti-reflective iav. Nws tuaj yeem hais tias qhov no yog cov kauj ruam tseem ceeb tshaj plaws nyob rau hauv tag nrho cov txheej txheem tsim khoom ntawm cov iav los tiv thaiv. Los ntawm daim ntawv thov ntawm micro - thiab nano-scale coatings, lub teeb pom kev ntawm lub iav nto tuaj yeem txo qis heev. Yog li ntawd, qhov kev ua tau zoo ntawm cov iav tau raug txhim kho, thiab qhov kev cuam tshuam tuaj yeem raug txo. Cov coatings no tsim ib qho teeb meem uas lub teeb tsis muaj kev cuam tshuam los ntawm cov iav nto destructively cuam tshuam rau ib leeg, yog li tshem tawm ib feem tseem ceeb ntawm kev xav.
Txheej daim ntaub ntawv nyob rau hauv lub chaw tsim khoom ntawm anti-reflective iav
Muaj ntau txoj hauv kev los kho cov iav nto los tsim cov khoom tiv thaiv kev xav. Cov txheej txheem feem ntau muaj xws li tshuaj etching, lub cev vapor deposition (PVD), thiab tshuaj vapor deposition (CVD).
Tshuaj etching
Tshuaj etching yog ib qho ntawm cov txheej txheem qub tshaj plaws thiab feem ntau siv rauua AR iav. Cov txheej txheem suav nrog dipping iav rau hauv cov tshuaj lom neeg los xaiv tshem tawm cov khoom nto. Los ntawm kev tswj cov txheej txheem etching, anti-reflection iav manufacturers tuaj yeem tsim cov qauv microscopic uas txo qhov kev xav.
Nws ua haujlwm li cas:Kho iav nrog kua qaub los yog lwm yam tshuaj reactive etches iav nto. Cov txheej txheem no yuav tsum muaj ib theem ntawm kev nthuav dav. Lub degree thiab qauv ntawm etching txiav txim siab qhov ua tau zoo ntawm iav raws li cov khoom siv los tiv thaiv kev cuam tshuam. Etching hloov cov qauv saum npoo ntawm iav, tsim microgrooves. Thaum lub teeb hits, lub iav nto scatters qhov teeb meem teeb meem, txo tus nqi ntawm kev xav.
Qhov zoo:Tus nqi ntawm cov tshuaj etching yog qhov tsawg thiab tuaj yeem ua tau ntau yam. Nws yog feem ntau ntau dua los ua cov iav los tiv thaiv hauv daim ntawv no. Nws yog feem ntau siv hauv architectural iav, vim hais tias architectural iav yuav tsum tau siv cov khoom tiv thaiv kev cuam tshuam rau qhov chaw loj.
Lub cev Vapor Deposition (PVD)
Lub cev vapor depositionyog ib txoj hauv kev zoo tshaj plaws rau kev siv cov tshuaj tiv thaiv kev cuam tshuam. Nyob rau hauv cov txheej txheem no, lub iav yog muab tso rau hauv ib lub tshuab nqus tsev chamber thiab ib tug nyias txheej ntawm anti-reflective khoom yog muab tso rau saum npoo los ntawm ib tug vaporization txheej txheem.
Nws ua haujlwm li cas:Cov khoom siv zoo li hlau oxides (xws li silicon dioxide lossis titanium dioxide) tuaj yeem ua rau vaporized hauv lub tshuab nqus tsev. Cov evaporated hais condense nyob rau saum npoo ntawm iav, tsim ib zaj duab xis nyias. Lub thickness thiab uniformity ntawm zaj duab xis yuav tsum tau kev tswj kom meej, ib tug txheej txheem uas yuav tsum tau tsis tsuas yog advanced cov cuab yeej, tab sis kuj muaj ntau lub siab ntev. Qhov no yog ib qho tseem ceeb heev rau kev tsim cov iav ua haujlwm siab.
Qhov zoo:Txawm hais tias lub cev vapor deposition txoj kev xav tau qee yam khoom siv, ntauanti-reflective iav manufacturerskuj kam sim txoj kev no. Vim tias PVD tuaj yeem tswj cov txheej txheej tuab heev. Qhov no yog qhov tseem ceeb los xyuas kom meej tias lub teeb tsis muaj qhov cuam tshuam los ntawm cov txheej txheem sib txawv ntawm cov txheej txheem muaj kev cuam tshuam cuam tshuam, tshem tawm qhov kev xav tau zoo. Qee qhov kev thov cov cuab yeej siv tau zoo rau kev tsim khoom hauv txoj kev no. Zoo li lub koob yees duab lo ntsiab muag thiab cov cuab yeej tshawb fawb.
Tshuaj vapor deposition
Chemical vapor deposition (CVD) yog lwm txheej txheem nqus tsev vacuum. Tab sis nws muaj cov tshuaj tiv thaiv ntawm vapor theem precursor, uas tuaj yeem tsim ib qhoanti-reflective zaj duab xisntawm iav nto.
Nws ua haujlwm li cas:Txoj kev no yog ua kom paub cov tshuaj tiv thaiv roj sib tov rau hauv lub tshuab nqus tsev. Cov pa roj react nrog ib leeg los ua ib qho yeeb yaj kiab. Cov yeeb yaj kiab feem ntau yog tsim los ntawm cov ntaub ntawv xws li silica, uas txo cov teeb pom kev zoo thaum txhim kho kev sib kis.
Qhov zoo:CVD ua kom cov txheej txheej tsis sib xws ntawm cov duab nyuaj, zoo tagnrho rau cov khoom 3D thiab qhov tsis sib xws. Cov txheej txheem kuj tsim coatings nrog zoo heev adhesion thiab durability.
