Cov khoom siv laser kev nyab xeeb ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov neeg siv los ntawm qhov muag thiab tawv nqaij puas. Txawm li cas los xij, muaj kev nkag siab tsis zoo txoglaser kev ruaj ntseg shieldsthiablaser tsom iav kev ruaj ntseg.
1. Qhov sib txawv ntawm laser kev ruaj ntseg shields thiab tsom iav
Laser tsom iav kev nyab xeeb tsuas yog tiv thaiv lub qhov muag ntawm cov hluav taws xob ncaj qha lossis tawg tawg nyob rau hauv qee qhov kev ntsuas hluav taws xob. Piv txwv li, class I lasers (<1mW) generally use safety glasses. Class II lasers (1-5mW) may use glasses or shields depending on power. Glasses do not provide protection for other body parts.
Laser kev ruaj ntseg shields yog lub cev enclosures uas muab tag nrho lub cev tiv thaiv los ntawm enclosing tag nrho cov laser apparatus thiab beam txoj kev. Shields tiv thaiv laser emission yog tias qhib thiab raug ntsuas kom muaj qhov tshwj xeeb tshaj plaws ntawm lub zog laser, lub zog, thiab kab teeb. Piv txwv li, chav kawm III lasers (5-500mW) yuav tsum siv cov ntaub thaiv npog nrog rau cov tsom iav siab. Class IV thiab saum toj no lasers feem ntau tsuas yog ua haujlwm nyob rau hauv ib daim ntaub thaiv npog.

2. Kev tsis ntseeg txog kev muaj peev xwm
Ib qho kev xav tsis zoo yog tias cov ntaub thaiv npog thiab iav tuaj yeem siv sib hloov. Txawm li cas los xij, ua kom qhov muag pom qhov ntom ntom ntawm cov iav tsis hloov lawv mus rau hauv daim ntaub thaiv npog - nws tsuas yog txhim kho qhov muag tiv thaiv hauv thaj chaw tiv thaiv. Cov tsom iav cia siab rau thaiv cov teeb tawg tawg tawg thaum cov ntaub thaiv npog npog tag nrho cov nqaj.
Lwm qhov kev xav tsis zoo yog tias cov ntaub thaiv npog ib leeg txaus. Secondary reflections nyob rau hauv ib daim ntaub thaiv npog tseem tuaj yeem nthuav tawm ob lub qhov muag yam tsis muaj cov tsom iav uas tsim nyog hnav hauv qab.
Laser curtains qee zaum tsis meej pem nrog cov ntaub thaiv npog tab sis lawv tsis ua tiav cov kab teeb los yog muaj kev nyab xeeb muaj cov pa tawm ncaj qha xws li cov ntaub thaiv npog zoo. Curtains thaiv qhov xwm txheej pom tsis yog qhov muaj kab ntsig tag nrho.
3. Piv txwv ntawm kev siv tsis raug
Siv ib qho kev nyab xeeb iav ua rau lub qhov muag kub hnyiab thaum lub sij hawm 5W laser ua haujlwm vim yog tshaj qhov ntsuas iav. Kev raug ncaj qha thaum xav ib daim ntaub hloov pauv rau daim ntaub thaiv kuj tuaj yeem ua rau tawv nqaij puas tsuaj loj.
4. Cov ntaub thaiv npog tsim nyog
Ib qho zoo tagnrho daim thaiv npog tag nrho ntawm txoj kev nqaj nrog absorbing sab hauv hauv ob sab phlu thiab tsis tshua muaj qhov rooj qhov rooj. Nws nta tsis siv neeg kaw uas txiav lub laser yog qhib, ua tau raws li IEC cov qauv. Cov ntaub thaiv npog uas muaj cov kab teeb hauv chav kawm IV feem ntau muaj cov khoom no kom muaj kev nyab xeeb ntawm lub zog siab tshaj plaws.
Hauv cov ntsiab lus, laser kev nyab xeeb yuav tsum raug xaiv cov ntaub thaiv npog lossis tsom iav raws li cov chav kawm laser, wavelength, lub zog thiab thaj chaw siv. Kev nkag siab txog kev muaj peev xwm ntawm txhua tus pab ua raws li cov txheej txheem kev nyab xeeb kom raug.
