Lub advent ntawm xiav diode lasers nyob rau hauv lub realm ntawm laser technology yeej yog ib tug kev ua si-hloov, paving txoj kev rau loj hlob thiab expansions nyob rau hauv ntau yam lag luam. Cov lasers no tau pom cov ntawv thov hauv kev txhim kho cov ntaub ntawv khaws cia hauv cov neeg siv khoom siv hluav taws xob, hloov kho cov txheej txheem kho mob, thiab tsav mus rau kev tshawb fawb tshawb fawb. Txawm li cas los xij, zoo li txhua lub tshuab muaj zog, lub zog loj xav tau lub luag haujlwm loj, tshwj xeeb tshaj yog thaum nws los txog rau kev ntsuas kev nyab xeeb. Ib lo lus nug tseem ceeb tshwm sim:Cov tsom iav xim dab tsi yuav tsum hnav kom nyab xeeb saib xiav diode laser?
Cov xov xwm no yog tsom rau kev tsom xam qhov tob ntawm cov yam ntxwv tsim nyog uas cov tsom iav tsom iav tsom iav lossis tsom iav tsom iav yuav tsum muaj kom muaj kev tiv thaiv zoo tiv thaiv lub teeb xiav xiav lub teeb tawm los ntawm cov lasers no. Peb yuav delve rau hauv qhov tseem ceeb ntawm wavelength range, optical density, certification standard, kev nplij siab thiab haum, reflective coatings, thiab sab shields nyob rau hauv xaiv lub tsim nyog eyewear rau kev nyab xeeb kev soj ntsuam ntawm xiav diode lasers.
Wavelength Range
Lasers emit coherent lub teeb ntawm ib lub wavelengths, thiab xiav diode lasers feem ntau ua hauj lwm nyob rau hauv qhov ntau ntawm 450-490 nanometers. Txhawm rau tiv thaiv qhov tshwj xeeb spectrum no, tsom iav kev nyab xeeb laser yuav tsum qhia meej txog kev tiv thaiv rau lub teeb xiav lub teeb wavelength. Cov iav yuav tsum qhia meej meej tias lawv muaj kev tiv thaiv nyob rau hauv qhov ntau ntawm koj lub diode laser emission spectrum.
Optical Density (OD)
Optical density yog ib qho kev ntsuas ntawm qhov kev tiv thaiv los ntawm cov tsom iav. Thaum pom lub laser xiav, OD ntawm 4 lossis siab dua yog pom zoo. Qhov kev ceev ntawm qhov muag pom no txhais tau hais tias cov tsom iav txo qhov kev siv ntawm lub teeb laser los ntawm qhov zoo ntawm 10,000 (10^4). Hauv lwm lo lus, yog tias lub laser tso tawm 10, 000 units ntawm lub teeb, lub tsom iav kev nyab xeeb tsuas yog tso cai rau 1 units hla, muab kev tiv thaiv siab rau cov neeg siv lub qhov muag.
Ntawv pov thawj Standards
Txhawm rau kom ntseeg tau tias cov tsom iav laser kev nyab xeeb ua tau raws li cov qauv kev nyab xeeb thoob ntiaj teb, lawv yuav tsum tau lees paub raws li cov qauv lees paub xws li ANSI Z136.1 hauv Tebchaws Meskas lossis EN 207/208 hauv Tebchaws Europe. Cov qauv no tau lees paub tias cov tsom iav tau raug sim thiab pom zoo rau lawv txoj kev npaj siv thiab muab kev tiv thaiv kev tiv thaiv kev tiv thaiv hluav taws xob laser.
Kev nplij siab thiab haum
Kev nplij siab thiab haum yog yam tseem ceeb uas yuav tsum tau xav txog thaum xaiv cov tsom iav laser, tshwj xeeb tshaj yog tias koj npaj yuav hnav lawv rau lub sijhawm ntev. Ib nkawm looj tsom iav zoo yuav pab tswj kev ua haujlwm ntawm tes yam tsis muaj kev cuam tshuam vim tsis xis nyob. Kev haum kom zoo xyuas kom tsis muaj qhov khoob qhov twg lub teeb laser tuaj yeem nkag mus thiab muaj feem cuam tshuam rau lub qhov muag.
Reflective Txheej
Qee cov tsom iav kev nyab xeeb laser muaj cov txheej txheej uas qhia txog lub teeb laser es tsis txhob nqus nws. Qhov txheej txheej ntxiv no muab kev tiv thaiv ntxiv vim nws tiv thaiv lub zog laser los ntawm kev nqus mus rau hauv cov khoom ntawm lub lo ntsiab muag. Reflective coatings tuaj yeem txhim kho lub neej ntev ntawm cov iav tsom iav los ntawm kev txo qhov kev pheej hmoo ntawm lub lens puas los ntawm kev raug lub teeb laser ntev.
Sab Shields
Sab shields yog ib qho tseem ceeb ntawm kev saib rau hauv laser tsom iav kev nyab xeeb. Lawv muab kev tiv thaiv ntxiv los ntawm kev npog ntau dua ntawm tus neeg siv lub ntsej muag, tiv thaiv tsis muaj teeb meem laser nkag los ntawm ob sab. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum ua haujlwm nrog cov lasers muaj zog uas txawm tias qhov sib txawv me me los ntawm cov kab ncaj nraim tuaj yeem ua rau qhov muag raug mob.
Xaus
Raws li xiav diode lasers txuas ntxiv thawb ciam teb ntawm kev tsim kho tshiab, kev coj ua lub luag haujlwm yuav tsum yog qhov ua ntej ntawm lawv daim ntawv thov. Los ntawm kev nkag siab thiab ua raws li qhov tsim nyog ntsuas kev nyab xeeb, xws li hnav cov tsom iav laser tsim nyog, cov neeg ua haujlwm thiab cov neeg nyiam tuaj yeem siv lub zog ntawm xiav laser tshuab kom nyab xeeb. Cov looj tsom iav tiv thaiv kom raug tsis yog tsuas yog tiv thaiv tib neeg nkaus xwb tab sis kuj tseem txhawb nqa kev loj hlob thiab kev vam meej ntawm kev lag luam uas vam khom rau qhov kev siv thev naus laus zis no.
Hauv kev xaus, thaum ua haujlwm nrog xiav diode lasers, nws yog ib qho tsim nyog yuav tsum hnav tsom iav kev nyab xeeb laser uas npog qhov tshwj xeeb wavelength ntau yam emissions los ntawm lub laser, muaj ib tug txaus optical ceev, ua raws li thoob ntiaj teb cov qauv ntawv pov thawj, muaj kev nplij siab thiab haum haum, muaj xws li reflective. coatings ntxiv kev tiv thaiv, thiab feature sab shields los tiv thaiv peripheral raug. Nrog rau cov kev xav hauv siab, ib tus tuaj yeem ua kom muaj kev tiv thaiv qhov muag siab tshaj plaws thaum koom nrog cov thev naus laus zis thev naus laus zis no.
