Kev nce qib ntawm thev naus laus zis tau coj cov cuab yeej laser rau hauv peb lub neej niaj hnub thiab kev siv tshuab. Lasers, paub txog lawv cov precision thiab siab zog concentration, ua rau muaj kev txhawj xeeb txog kev nyab xeeb yog tias tsis siv kom raug. Qhov no yog qhov tseeb tshwj xeeb rau Class 3 laser li, uas poob ntawm lub zog qis thiab siab zog lasers. Txawm hais tias lawv tsis zoo li ua rau qhov muag raug mob nyob rau hauv ib txwm ua haujlwm, lawv tseem tuaj yeem ua rau muaj kev phom sij yog tias cov nqaj tau tsom lossis pom los ntawm kev pab kho qhov muag. Yog li ntawd, nkag siab txog cov tswv yim siv ntawm cov cuab yeej no thiab kev sivkev ntsuas kev nyab xeeb tsim nyogyog qhov tseem ceeb.
Daim ntawv thov ntawm Class 3 Laser Devices
Ib daim ntawv thov raug siv ntawm Class 3 lasers yog nyob rau hauv cov chaw kawm, uas cov kws qhia siv laser pointers nrog lub zog tso zis ntawm 5mW, cais raws li Class 3R. Cov cuab yeej no muaj kev nyab xeeb ntawm qhov kev nthuav qhia ib txwm nyob deb tab sis tuaj yeem ua rau lub qhov muag puas yog tias tau coj mus rau ib tus neeg lub qhov muag, tshwj xeeb tshaj yog siv cov lo ntsiab muag magnifying.
Lwm qhov piv txwv yog laser barcode scanners feem ntau pom nyob rau hauv cov khw muag khoom loj, uas feem ntau yog nyob rau hauv Chav Kawm 3B vim lawv lub zog ntau dua thiab muaj peev xwm txaus ntshai. Lub tshuab luam ntawv barcode nrog lub zog tso zis ntawm ib ncig ntawm 50mW tuaj yeem luam tawm cov khoom ntawm qhov deb, tab sis yog tias nws ua haujlwm tsis zoo thiab tswj lub laser tsis tswj, nws tuaj yeem ua rau mob qhov muag loj rau cov neeg ua haujlwm lossis cov neeg siv khoom.
Kev ntsuas kev nyab xeeb rau Class 3 Laser Devices
Txhawm rau txo cov kev pheej hmoo no, ntawm no yog qee qhov kev ntsuas kev nyab xeeb tshwj xeeb pom zoo rau Class 3 laser li:
Laser Safety Goggles: Rau cov kws qhia ntawv siv laser pointers, hnav cov tsom iav tiv thaiv uas ua tau raws li tus qauv ANSI Z136.1 zoo tuaj yeem tiv thaiv qhov muag raug mob laser.
Beam Limiters: Txhim kho cov kab teeb pom kev zoo ntawm lub laser scanners kom ntseeg tau tias txawm tias muaj kev ua haujlwm tsis zoo, lub nqaj tsis dhau qhov kev nyab xeeb.
Ceeb toom: Muab cov cim ceeb toom tseem ceeb hauv thaj chaw ua haujlwm laser, xws li "Caution: Laser Radiation," ceeb toom rau tib neeg kom paub txog kev nyab xeeb.
Kev cob qhia kws tshaj lij: Ua kom muaj kev cob qhia kev nyab xeeb laser rau cov neeg ua haujlwm ua haujlwm barcode scanners, qhia lawv cov txheej txheem kom raug thiab cov tswv yim xwm txheej ceev.
Kev siv tshwj xeeb ntawm Laser Shields
Thaum teeb tsa laser shields, tsis xws li txoj haujlwm, qhov loj me, thiab cov khoom siv yuav tsum raug xaiv raws li cov khoom siv laser tshwj xeeb thiab ib puag ncig ua haujlwm. Piv txwv li, hauv chav kuaj tshuaj siv Class 3B spectrometer, nws yuav tsim nyog rau nruab ib lub laser shield nrog siab reflectivity thiab durability. Qhov loj ntawm daim ntaub thaiv npog yuav tsum npog tag nrho cov peev txheej emission ntawm cov cuab yeej, thiab nws txoj hauj lwm yuav tsum nyob ze ntawm lub cuab yeej kom txo tau qhov kev pheej hmoo ntawm kev cuam tshuam thiab tawg tawg. Tsis tas li ntawd, cov khoom siv ntawm cov ntaub thaiv npog yuav tsum tiv taus ntev heev rau ultraviolet thiab infrared spectrums.
Los ntawm kev ua raws li cov kev ntsuas no, peb tuaj yeem ua kom ntseeg tau tias txawm tias thaum siv cov khoom siv phom sij rau Class 3 laser, peb tuaj yeem txo qhov tshwm sim ntawm kev nyab xeeb.
