Laser tsom iav kev nyab xeebtsis muaj universal "hnub tas sij hawm" luam tawm rau lawv zoo li zaub mov lossis tshuaj, tab sislawv ua degrade nyob rau lub sij hawm thiab yuav poob hauj lwm. Txawm hais tias cov ntaub ntawv yuav nyob twj ywm hauv lub cev rau xyoo, lawvoptical kev ua tau zoo thiab muaj peev xwm tiv thaiv tuaj yeem txo qisvim ib puag ncig raug, hnav, thiab tshuaj lom neeg sib cuam tshuam. Yog li ntawd,laser kev ruaj ntseg eyewear muaj lub neej ua haujlwmthiab yuav tsum tau tshuaj xyuas tsis tu ncua thiab hloov thaum muaj kev cuam tshuam.
Hauv qab no yog kev tshawb fawb -raws li, cov qauv- ua raws cov txheej txheem ntawm kev cuam tshuam rau lub neej ntev thiab kev coj ua zoo tshaj plaws rau kev tswj hwmlaser tsom iav kev ruaj ntseg.
1. Yog vim li casLaser Safety GlassesYuav "Tsev" (Txawm tias tsis muaj hnub)
Txawm hais tias tsis muaj kev tswj hwm thoob ntiaj teb tswj hwm lub sijhawm tas sijhawm, ntau yam ua rau txo kev tiv thaiv:
A. Lens Degradation
Kos, abrasions, los yog huabtawg lub teeb thiab tej zaum yuav tsim micro-channels uas laser hluav taws xob nkag mus.
UV raug(los ntawm lub hnub ci los yog lub teeb pom kev hauv lab) tuaj yeem ua rau cov dyes lossis coatings hauv polycarbonate lossis iav lo ntsiab muag.
Thermal stresslos ntawm kev rov ua dua mus rau siab - lub zog lasers - txawm tias qis dua qhov pib puas tsuaj - tuaj yeem ua rau qaug zog optical lim.
B. Txheej Delamination
Ntau lub tsom iav laser siv nyias -film cuam tshuam los yog nqus cov txheej txheem kom ua tiav qhov siab Optical Density (OD). Nyob rau lub sijhawm:
Cov av noo, ntxuav cov kuab tshuaj, lossis qhov kub thiab txias tuaj yeem ua rautxheej peeling los yog bubbling.
Cov coatings puastsis thaiv lub hom phiaj wavelength zoo.
C. Ncej Deterioration
Cov kab nrib pleb tawg, tawg, lossis nkig thav duab tuaj yeem tuav lub lens kom ruaj ntseg.
Elasticity poob hauv lub tuam tsev txhais caj npab txo qhov haum, ua rau muaj kev pheej hmoo ntawm peripheral raug.
2. Cov qauv hais li cas txog Kev Pabcuam Lub Neej
ANSI Z136.1 (US)
Yuav tsum taulooj tsom iavraug tshuaj xyuas ua ntej txhua qhov kev siv(Nqe 8.4.2).
Xeev:"Cov looj tsom iav uas puas los yog degraded yuav tsum raug tshem tawm ntawm kev pabcuam."
Tsis qhia lub sijhawm txwv tab sis hais txogmob -raws li hloov.
EN 207 (Tebchaws Europe)
tsom rauthawj daim ntawv pov thawj(hluav taws-los ntawm kev tsis kam), tab sis Annex A sau ntawv:
"Kev tiv thaiv cov ntxaij lim dej yuav tsum tau kuaj xyuas tsis tu ncua rau kev puas tsuaj ... txhua qhov cim ntawm degradation txhais tau tias cov lim yuav tsum raug muab pov tseg."
Cov neeg tsim khoom feem ntau pom zoo alub neej ua haujlwm siab tshaj plaws ntawm 5 xyoosnyob rau hauv tej yam kev mob -txawm yog tsis siv-vim cov khoom aging.
3. Daim ntawv tshuaj ntsuam xyuas
Ua ntej txhua yam siv, kos rau:
✅ Pom pom khawb los yog qhovntawm qhov chaw lens
✅ Discoloration, haze, los yog huab
✅ Peeling, flaking, los yog npuasntawm coatings
✅ Cracks nyob rau hauv lo ntsiab muag los yog thav duab
✅ Loos fittings los yog tawg lub qhov ntswg pads / caj npab
✅ Faded los yog unreadable labeling(Wavelength, OD, Standard)
🔍 Tswv yim: Tuav tsom iav mus txog lub teeb ci. Yog tias koj pom pinholes, streaks, lossis tsis sib xws, hloov lawv.
4. Thaum Yuav Hloov - Cov Ntsiab Lus Tseem Ceeb
Hloovlaser tsom iav kev ruaj ntsegtam sim ntawd yog:
Lawv twb tauraug rau lub laser pulse los yog beam saum lawv cov peev xwm ntsuas(txawm tias tsis pom kev puas tsuaj).
Lawv qhiatej yam tsis xws luag los yog kho qhov muag(saib daim ntawv teev npe saum toj no).
Covdaim ntawv lo tsis muaj lossis tsis raug cai(koj tsis tuaj yeem txheeb xyuas wavelength/OD).
Lawv yoglaus dua 5 xyoos, tshwj xeeb tshaj yog khaws cia rau hauv qhov chaw kub, av noo, lossis tshav ntuj.
Lawv twb tauntxuav nrog cov tshuaj hnyav(piv txwv li, acetone, ammonia, cawv- cov tshuaj ntxuav tes tshwj tsis yog pom zoo los ntawm cov chaw tsim khoom).
5. Kev saib xyuas kom tsim nyog txhawm rau txuas lub neej ntev
Ntxuav maj mamnrog xab npum me me, dej, thiab daim ntaub mos microfiber.
Khaws rau hauv ib rooj plaub nyuajdeb ntawm tshav ntuj ncaj qha, tshav kub, thiab cov kuab tshuaj.
Tsis txhob muab lo ntsiab muag ntsej muag - downntawm qhov chaw.
txhob sharenruab nrab ntawm cov neeg siv los txo kev hnav thiab kev sib kis.
Cov ntsiab lus: Tsis Muaj Hnub Nyoog Kawg, Tab sis Lub Neej Ua Haujlwm Li Cas
Laser tsom iav kev nyab xeebtsis txhob "tiav" ntawm daim ntawv qhia hnub-tab sis lawvua tas sij hawm hauv kev ua haujlwm. Lawv kev tiv thaiv kev ncaj ncees nyob ntawm cov khoom ruaj khov, tuav, thiab ib puag ncig. Kev tshuaj xyuas tsis tu ncua thiab kev hloov pauv tsis tu ncua yog qhov tseem ceeb kom ntseeg tau tias lawv txuas ntxiv muab cov khoomOptical Density (OD)thiabwavelength - tshwj xeeb thaivxav tau rau koj laser system.
Kev xyaum zoo tshaj plaws: Kholaser tsom iavraws liCov cuab yeej siv kev nyab xeeb tseem ceeb- tsis siv cov khoom siv pov tseg. Thaum tsis ntseeg txog tus mob lossis hnub nyoog,hloov nws. Koj lub zeem muag yog irreplaceable.
