Muaj ntau hom substrates rau cov tsom iav thiab lens, xws li CR39, PC (polycarbonate), 1.53 Trivex156, nruab nrab refractive index yas, iav, thiab lwm yam. Rau cov lens kho, qhov transmittance ntawm ob qho tib si resin thiab iav lens tsuas yog li 91%, thiab qee lub teeb raug reflected rov qab los ntawm ob qhov chaw ntawm lub lens. Qhov reflection ntawm cov lens tuaj yeem txo qhov transmittance ntawm lub teeb thiab tsim cov duab cuam tshuam hauv retina, cuam tshuam rau qhov zoo ntawm kev thaij duab thiab qhov tsos ntawm tus neeg hnav. Yog li ntawd, qhov chaw ntawm lub lens feem ntau yog coated nrog ib txheej zaj duab xis tiv thaiv kev cuam tshuam, ib txheej lossis ntau txheej ntawm zaj duab xis los txhim kho qhov zoo. Tib lub sijhawm, cov neeg siv khoom tau muab tso rau pem hauv ntej qhov yuav tsum tau siab rau lub neej kev pabcuam, kev tiv thaiv khawb, thiab kev huv ntawm cov lens. Yuav kom ua tau raws li cov kev cai saum toj no, cov qauv zaj duab xis ntawm cov tsom iav tsom iav feem ntau suav nrog ib txheej hardening, ib txheej tiv thaiv kev cuam tshuam, ib txheej tiv thaiv static (xws li ITO), thiab ib txheej tiv thaiv fouling.
Cov tsom iav dub yog cov khoom siv tiv thaiv kev ua haujlwm rau kev tiv thaiv lub qhov muag hauv qab lub teeb ci ntsa iab. Kev hnav cov tsom iav no tuaj yeem thaiv cov teeb ultraviolet thiab infrared, thaum cov xim ntawm qhov chaw sab nraud tsis hloov, tsuas yog qhov muaj zog ntawm lub teeb hloov pauv. Cov tsom iav dub muaj cov tsom iav dub uas muaj xim, polarizing iav txheej, thiab lwm yam, uas tuaj yeem nyob ib leeg lossis siv ua ke. Cov txheej iav feem ntau yog sib xyaw nrog cov tsom iav dub lossis polarized thiab siv rau sab nraud (qhov chaw convex) ntawm lub lens. Qhov kev xa tawm lub teeb tsawg dua ua rau nws tsim nyog heev rau ntau yam dej, daus, thiab qhov chaw siab, thiab tseem muab rau cov neeg siv nrog kev paub txias hnav. Cov tsom iav dub no feem ntau yog los txheej hlau lossis zaj duab xis dielectric rau sab nraud ntawm cov tsom iav kom txhim kho nws qhov kev cuam tshuam, txo qhov kev xa tawm thiab tiv thaiv lub qhov muag.
Cov tsom iav photochromic yog ib hom tsom iav ntse tshiab uas pom tseeb hauv tsev. Sab nraum zoov, vim yog lub teeb ultraviolet, cov khoom siv photochromic ntawm cov tsom iav hloov pauv, ua rau cov iav tsaus ntuj thiab txo qhov kev xa tawm ntawm lub teeb. Rov qab mus rau hauv tsev, cov khoom siv rov qab mus rau lub xeev pom tseeb.
Nrog rau kev nce qib tas mus li ntawm thev naus laus zis, qhov kev thov rau kev tsim kho qhov muag, cov iav tsom iav, thiab cov yeeb yaj kiab kho qhov muag rau cov tsom iav xws li kev muaj tiag virtual (VR) thiab augmented reality (AR) kuj tseem nce ntxiv.
—— Tsab xov xwm no tau tshaj tawm los ntawm Guangdong Zhenhua Technology, ib qhoChaw tsim khoom ntawm cov tshuab txheej kho qhov muag.
