Laser tsom iav kev nyab xeeb yog tsim los tiv thaiv ob lub qhov muag los ntawm cov teeb meem laser hluav taws xob. Lawv cov kev ua tau zoo nyob ntawm ntau yam kev tsis sib xws, suav nrog Visible Light Transmission (VLT), Optical Density (OD), thiab kev faib tawm laser wavelength.
Visible Light Transmission (VLT)yog hais txog qhov pom lub teeb pom kev uas tuaj yeem dhau los ntawm lub qhov muag ntawm cov tsom iav. Nws feem ntau yog ntsuas raws li qhov feem pua, nrog qis VLT qhov tseem ceeb qhia tias tsis tshua muaj kev sib kis. VLT ncaj qha cuam tshuam rau tus neeg hnav lub peev xwm kom pom meej ntawm cov iav. Cov txiaj ntsig VLT siab yog tsim rau cov ntawv thov uas qhov pom kev zoo yog qhov tseem ceeb, qhov qis VLT qhov tseem ceeb yog qhov zoo tagnrho rau ib puag ncig nrog lub teeb pom kev zoo.
Optical Density (OD)yog ib qho kev ntsuas ntawm cov tsom iav 'muaj peev xwm attenuate tshwj xeeb wavelength laser teeb. Nws suav cov logarithm ntawm qhov sib txuas ntawm qhov xa tawm, qhia txog qhov pom ntawm lub teeb uas cov iav tuaj yeem thaiv. Cov txiaj ntsig OD siab dua sib raug rau kev tiv thaiv ntau ntxiv, vim tias lawv qhia txog kev txo qis dua hauv kev sib kis ntawm cov laser wavelengths tshwj xeeb. Kev xaiv kom zoo ntawm OD tus nqi nyob ntawm qhov muaj peev xwm laser wavelength thiab nws qib zog.
Raws li daim ntawv thov ntawm laser tsom iav kev nyab xeeb, lawv tuaj yeem muab faib ua ntau pawg, xws li:
1. Ultraviolet (UV) Laser Safety Glasses:Cov iav no yog tsim los tiv thaiv UV laser hluav taws xob, uas feem ntau ua haujlwm nyob rau hauv lub wavelength ntawm 180 txog 400 nanometers. UV lasers feem ntau yog siv rau hauv kev kho mob, kho hniav, thiab kev lag luam daim ntawv thov, thiab cov tsom iav rau UV tiv thaiv yuav tsum muaj qhov tsim nyog OD los lim tawm cov teeb meem UV hluav taws xob.
2. Pom tau thiab ze-Infrared (VIS-NIR) Laser Safety Glasses: Cov tsom iav no muab kev tiv thaiv los ntawm lasers ua haujlwm hauv qhov pom ntawm qhov ze-infrared spectrum, feem ntau yog li ntawm 400 txog 1400 nanometers. Cov tsom iav no yog tsim rau cov ntawv thov xws li laser pointers, alignment lasers, thiab qee qhov kev kho mob lasers siv hauv dermatology thiab ophthalmology.
3. Infrared (IR) Laser Safety Glasses: Infrared lasers ua haujlwm nyob rau hauv lub wavelength ntawm 1400 txog 10,600 nanometers, thiab IR laser kev nyab xeeb tsom iav yog tsim los tiv thaiv ob lub qhov muag ntawm cov wavelengths tshwj xeeb. Cov iav no feem ntau siv rau hauv kev lag luam xws li laser txiav, vuam, thiab cov khoom siv.
4. CO2 Laser Safety Glasses:CO2 lasers muaj lub wavelength ntawm ib ncig ntawm 10,600 nanometers, thiab siab CO2 laser tsom iav kev nyab xeeb yuav tsum tau los tiv thaiv cov high-powered infrared hluav taws xob tawm los ntawm cov lasers. Lawv yog qhov tseem ceeb rau cov tib neeg ua haujlwm nrog CO2 lasers hauv kev kho mob, kev lag luam, thiab kev tshawb fawb ib puag ncig.
Cov kev faib tawm no pab txhawm rau txheeb xyuas qhov tshwj xeeb ntawm wavelengths uas cov tsom iav tuaj yeem tiv thaiv tau zoo, ua rau cov neeg siv xaiv cov tsom iav uas tsim nyog tshaj plaws rau lawv daim ntawv thov laser.
Ntxiv nrog rau cov kev ntsuas thiab kev faib tawm, nws yog ib qho tseem ceeb uas yuav tau xav txog qhovyam ntxwv ntawm lub cevntawm laser tsom iav kev ruaj ntseg. Kev tsim thiab kev tsim ntawm lub thav duab thiab lo ntsiab muag, kev nplij siab, thiab kev sib haum xeeb tag nrho yog qhov tseem ceeb heev rau cov neeg siv kev lees paub thiab kev ua raws li cov cai tswj kev nyab xeeb. Ergonomic nta, xws li kho qhov ntswg qhov ntswg thiab lub tuam tsev txhais caj npab, pab txhawb kev nplij siab thiab kev ruaj ntseg ntawm cov tsom iav thaum hnav ntev, yog li ua rau cov neeg hnav ua raws thiab kev nyab xeeb.
Tsis tas li ntawd, lub lens xim plays lub luag haujlwm tseem ceeb hauv laser tsom iav kev nyab xeeb. Cov xim sib txawv ntawm lub lens yog tsim rau cov kev siv tshwj xeeb thiab ib puag ncig. Piv txwv li, cov lo ntsiab muag ntsuab muaj txiaj ntsig zoo hauv kev txo qis cov kab hluav taws xob liab thiab infrared, thaum lo ntsiab muag xiav yog tsim los tiv thaiv CO2 lasers. Qhov kev xaiv ntawm cov xim lo ntsiab muag yog ze ze rau lub laser wavelength thiab nws cov kev cai OD.
Thaum xaiv cov tsom iav kev nyab xeeb laser, nws yog ib qho tseem ceeb uas yuav tau xav txogdaim ntawv thov tshwj xeeb thiab cov teeb meem laser muaj feem cuam tshuam, nrog rau cov qauv kev nyab xeeb thoob ntiaj teb thiab cov kev cai. Ua raws li cov qauv xws li ANSI Z136 hauv Tebchaws Meskas thiab EN 207 hauv Tebchaws Europe kom ntseeg tau tias cov iav xaiv tau raws li qhov tsim nyog kev nyab xeeb rau kev tiv thaiv qhov muag hauv ib puag ncig laser.
Hauv kev xaus, cov txheej txheem thiab lub cev tsis zoo, kev faib tawm, thiab kev txiav txim siab tshwj xeeb ntawm daim ntawv thov ua lub luag haujlwm tseem ceeb hauv kev xaiv cov tsom iav laser. Los ntawm kev nkag siab txog cov xwm txheej no thiab lawv cov kev sib raug zoo, cov neeg siv tuaj yeem txiav txim siab kom paub tseeb tias qhov kev tiv thaiv zoo ntawm lawv ob lub qhov muag hauv ntau hom kev siv laser.
