Nrog rau lub hnub yug ntawm ruby laser nyob rau hauv 1960, laser tshuab tau dav siv nyob rau hauv kev lag luam kev ua.Ua li, vim hais tias nyob rau hauv ib puag ncig lub laser, kev puas tsuaj ntawm laser diffuse thiaj li xav rau tib neeg lub qhov muag tau tsim rau ntev, uas yog qhov tsis pom thiab tsis tuaj yeem, laser. kev tiv thaiv thev naus laus zis tau nyiam ntau dua thiab ntau dua.Hauv txog xyoo 1960, thaum lub laser yug, Tebchaws Asmeskas tau tsim lub ntsej muag ruby laser tiv thaiv tsom iav.Thaum, nyob hauv nruab nrab xyoo 1980s, nqus hom laser tiv thaiv tsom iav pib tau tsim hauv United Stateslaser source.Meanwhile, Shandong University tau tsim lub ruby laser tiv thaiv lub ntsej muag ntawm 0.694μm nyob rau thaum xyoo 1970s, thiab thawj qhov kev nqus hom laser tiv thaiv lub ntsej muag rau 532nm laser tshwm hauv Suav teb thaum xyoo 1990. Lub ntiaj teb tau txais qhov tseem ceeb rau laser. kev tiv thaiv, nrog rau cov koom haum thoob ntiaj teb, suav nrog lub koom haum saib xyuas kev noj qab haus huv hauv ntiaj teb (WHO), lub koom haum thoob ntiaj teb rau kev ntsuas qauv (ISO), inte rnational radiation tiv thaiv koom haum (IRPA), chaw ua haujlwm kev noj qab haus huv (BRH) nyob hauv Tebchaws Meskas, Asmeskas lub koom haum tus qauv (ANSI - Z - 136.1: 1993), European electrotechnical standardization pawg thiab lwm yam tau tshaj tawm cov qauv kev tiv thaiv laser, thiab tam sim no yog tus nquag nyob thoob ntiaj teb EN207 laser tiv thaiv cov qauv hauv European Union.
Hauv Suav Teb, GJB1762-93 yog qhov ntxov tshaj plaws ntawm kev siv tsom iav tiv thaiv tsom iav.
GJB1762-93 laser goggles txuj siv tau rau kev tsim, tsim, siv thiab kuaj ntawm laser tsom iav thiab lwm yam laser qhov muag tiv thaiv.Qhov qauv tso rau pem hauv ntej cov kev xav tau ntawm laser tsom iav tiv thaiv: kev ua kom pom, kev xav kom muaj kev noj qab haus huv, cim qhov yuav tsum tau ua, pom hauv thaj chaw pom , cov cai tiv thaiv tom qab. Nyob rau tib lub sijhawm, cov ncauj lus kom ntxaws yooj yim, tshwj xeeb tshaj yog qhov ua kom pom kev ua tau zoo thiab cov qauv tau muab tso rau pem hauv ntej.Laser tiv thaiv tsom iav yuav tsum ua raws li cov kev xav tau hauv qab no:
1. Tso lub teeb tiv thaiv tiv thaiv rau cov xim dub dub, thiab siv lub teeb ci incandescent 60W rau kev kuaj pom. Ntxiv nrog rau 5 hli ntug, saum npoo yog du tsis muaj khawb, ripples, npuas, impurities, thiab lwm yam.
2.Cov khoom siv lens no yog non-toxic, ntxhiab tsw thiab tsis txhawb.
3.Qhov qhov muag pom ntawm txoj haujlwm ntawm lub tsom iav qhia qhov laser daim ntawv (txuas ntxiv, mem tes, thiab lwm yam), kev tiv thaiv yoj, lub qhov muag tsis pom kev, thiab lwm yam piv txwv:" 532 D4 CW" ;.
4. Cov tsom iav tiv thaiv yuav tsum tuaj yeem tiv thaiv tiv thaiv kev puas tsuaj sab laser.
5. Tsis txhob ua rau lub laser teeb meem rau lwm tus.
Tshooj 1-2 ntawm cov qauv saum toj no tau qhia meej feem ntau ntawm cov khoom ntiag tug ntawm laser tiv thaiv cov khoom lag luam, uas yog, raws li qhov muag cov khoom lag luam, cov khoom lag luam tsim nyog tiav tau muaj qhov yooj yim tshaj plaws qhov pom tseeb, thiab cov seem ntawm cov khoom lag luam dua li lub lens yuav tsum tau ntsib qhov cov qauv khoom tsis muaj tshuaj lom thiab tsis muaj xim.
Hauv Tshooj 3, tus naj npawb yog qhov laser wavelength uas tuaj yeem tiv thaiv, 532 yog tus kab hluav taws xob laser ntawm 532nm. D yog OD, hu ua tus nqi ntsuas kho qhov muag, uas yog nkag siab zoo li lub logarithm ntawm qhov sib piv ntawm cov teeb meem hluav taws xob (EI) kom kis tau lub teeb zog (EL) ntawm 10.
Cov txheej txheem ntawm Cov Lus 4 ntawm cov ntsiab lus hais tias kev xaiv ntawm tsom iav tiv thaiv tsom iav yuav tsum them sai sai rau kev tiv thaiv ntawm lub sab ntawm cov tsom iav, xws li cov tsom iav myopia dav dav thiab tsom iav tsom iav style tsis tau raws li qhov yuav tsum tau ua, thiab tshwj xeeb tshaj yog tsom iav cliparenot nyob rau hauv txoj kab nrog cov kev cai. Txoj cai no yog vim lub diffuse reflection effect ntawm lasers.As ntev npaum li qhov muaj qhov cuam tshuam nyob ib puag ncig, ntxiv rau qhov ncaj qha laser nqaj, muaj ntau lub laser kab teeb ci hauv cov lus qhia sib txawv hauv ib puag ncig, yog li cov tsom iav tiv thaiv tsom iav yuav tsum tau xaiv tsis tsuas yog tiv thaiv cov nqaj ntsia rau tsom iav, tab sis kuj tseem tiv thaiv cov diffuse laser los ntawm cov ces kaum sib txawv rau hauv lub qhov muag. Raws li tus qauv no, peb hais kom peb tsis xaiv laser tiv thaiv gogglesbased ib qho kev cuam tshuam txoj ntsiab cai, vim hais tias qhov cuam tshuam ntawm laser tiv thaiv. nyhuv yog xaiv rau hom teeb ci.
Qhov thib tsib tus qauv ntsiab lus outthat qhov chaw tsis tau xav txog ntawm lub lens yuav tsum tsis yog cov khoom siv hlau. Txhawm rau txhim kho kev nkag siab ntawm kev ntxhib los mos thiab tsim cov tsom iav, ntau cov tuam ntxhab ntxiv qee cov khoom hlau thiab qhov chaw, thiab cov khoom lag luam tsis tau raws li cov qauv kev nyab xeeb.Thaum tib lub sijhawm, ib hom kev tiv thaiv tsom iav kuj yuav ua rau muaj kev cuam tshuam. raug mob rau lwm tus.
Thov nco tseg: txhua lub tshuab ntxuav laser, laser npav thiab laser vuam tshuab yog nruab nrog cov qauv kev tiv thaiv zoo rau koj lub qhov muag' kev nyab xeeb.
