Thaum ua haujlwm lossis ua haujlwm hauv ib puag ncig laser, kev tiv thaiv qhov muag yog qhov tseem ceeb.Laser tsom iav kev nyab xeebyog tus yuam sij rau kev tiv thaiv lub qhov muag los ntawm teeb meem laser hluav taws xob, thiab lawv cov kev ua tau zoo feem ntau yog ntsuas los ntawm ob qhov tsis xws li: optical density (OD) thiab pom lub teeb transmittance (VLT). Nkag siab txog ob qhov kev txwv no thiab lawv txoj kev sib raug zoo rau ib leeg yog qhov tseem ceeb rau kev xaiv cov tsom iav zoo laser.
Cov ntsiab lus piav qhia ntawm optical ntom ntom (OD)
Optical ceev qhia lub peev xwm ntawmlaser tsom iav kev ruaj ntsegkom attenuate laser beams. Nws txhais tau tias yog qhov tsis zoo ntawm tus lej logarithm ntawm qhov sib piv ntawm qhov teeb meem teeb pom kev zoo rau kev sib kis lub teeb siv, txhais tau tias ntau dua OD qhov tseem ceeb tso cai rau lub zog laser tsawg dhau los ntawm lub lens, muab kev tiv thaiv ntau dua. Piv txwv li, tsom iav nrog OD ntawm 4 tsuas yog tso cai rau 1/10, 000 ntawm lub teeb kom dhau mus, uas muab kev tiv thaiv zoo thiab txo qhov ua tau ntawm laser puas.
Qhov tseem ceeb ntawm pom lub teeb pom kev zoo (VLT)
VLT yog ib qho kev ntsuas ntawm ntau npaum li cas pom lub teeb lub lens tso cai rau hla, feem ntau qhia raws li feem pua. Tus nqi VLT siab txhais tau tias ntau lub teeb tuaj yeem dhau los ntawm cov tsom iav, tso cai rau tus neeg hnav kom pom meej dua; tab sis yog tias VLT siab dhau lawm, nws tuaj yeem txo qhov thaiv cov nyhuv ntawm cov laser wavelengths tshwj xeeb. Qhov tsim nyog theem ntawm VLT nyob ntawm qhov teeb pom kev zoo ntawm qhov chaw ua haujlwm. Piv txwv li, cov neeg ua haujlwm sab hauv tsev lossis hauv qhov chaw tsaus ntuj yuav xav tau VLT siab dua kom muaj kev pom meej meej.
Kev sib raug zoo ntawm OD thiab VLT
Muaj kev sib raug zoo ntawm OD thiab VLT hauvlaser tsom iav kev ruaj ntseg. Kev nce OD feem ntau ua rau qis VLT, thiab rov ua dua. Txawm li cas los xij, qhov kev sib raug zoo no tsis tau txhais hais tias ob qho tib si tsis tuaj yeem coj mus rau hauv tus account. Niaj hnub nimno eyewear manufacturing technology, suav nrog ntau txheej txheej cuam tshuam txheej txheej thiab photochromic technology, tso cai rau kev tsim cov tsom iav laser nrog ob qho tib si siab OD thiab tau txais VLT. Cov tsom iav no tau tsim los ua kom muaj qhov thaiv qhov tshwj xeeb ntawm lub teeb ntawm lub teeb laser thaum tso cai kom pom lub teeb txaus kom dhau los kom ntseeg tau tias tus neeg hnav tuaj yeem ua haujlwm ib txwm.
Cov lus xaus thiab cov lus pom zoo
Thaum xaivlaser tsom iav kev ruaj ntseg, cov neeg siv yuav tsum xav txog lawv tus kheej cov kev pheej hmoo raug, ib puag ncig ua haujlwm, thiab cov haujlwm tshwj xeeb. Cov iav zoo tagnrho yuav tsum muaj kev tiv thaiv txaus thaum tseem ua kom cov neeg siv pom kev nplij siab thiab ua haujlwm tau zoo thaum ua haujlwm. Yog li ntawd, nws yog ib qho tseem ceeb heev rau kev sab laj tus kws tshaj lij kev nyab xeeb thiab sim ua cov iav sib txawv los txiav txim siab qhov sib xyaw ua ke ntawm OD thiab VLT. Nrog rau kev nce qib ntawm cov thev naus laus zis, yav tom ntej laser tsom iav kev nyab xeeb yuav muab cov kev hloov pauv tau yooj yim dua thiab kho kom zoo dua hauv ob qho tib si.
