Laser Safety Glasses tiv thaiv Laser Radiation?

Wb tham txog Laser Radiation thiab Laser Safety Glasses Protection.

Laser hluav taws xob yog ib hom hluav taws xob hluav taws xob hluav taws xob uas emits high-zog, coherent lub teeb. Lasers yog siv nyob rau hauv ntau yam teb, nrog rau cov tshuaj, kev tsim, kev tshawb fawb, thiab kev lom zem. Txawm li cas los xij, lawv tuaj yeem ua rau muaj kev phom sij rau tib neeg lub qhov muag thiab tawv nqaij yog tias tsis ua raws li kev ntsuas kev nyab xeeb.

Laser tsom iav kev nyab xeebtiv thaiv lub qhov muag los ntawm teeb meem laser hluav taws xob. Lawv tau tsim los nqus lossis cuam tshuam cov wavelengths ntawm lub teeb nyob ntawm seb hom laser siv. Laser tsom iav kev ruaj ntseg yuav tsum tau xaiv raws li lub wavelength, lub zog ceev, thiab lub sij hawm raug. Nws yog ib qho tseem ceeb uas yuav tsum xaiv cov looj tsom iav uas tsim nyog los tiv thaiv cov hluav taws xob laser los ntawm kev puas tsuaj rau lub qhov muag lossis ua rau raug mob.

Laser tsom iav kev nyab xeebyuav tsum tau hnav los ntawm cov tib neeg uas ua haujlwm nrog lasers lossis raug rau cov hluav taws xob laser, xws li cov kws kho mob, kws kho mob, kws tshawb fawb, thiab cov neeg ua haujlwm ua haujlwm. Cov looj tsom iav yuav tsum ua kom tau raws li cov qauv kev nyab xeeb uas tau teev tseg los ntawm American National Standards Institute (ANSI) Z136 series, thiab Txoj Cai Tswj Haujlwm Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv (OSHA).

Vim li cas thiaj tiv thaiv hluav taws xob laser?

1. Vim hais tias lub laser muaj zoo directivity thiab me me divergence, lub laser tsis muaj divergence ua kom lub zog concentrated nyob rau hauv ib tug ntev deb. Yog tias lub zog nkag mus rau hauv lub qhov muag, nws yuav ua rau qhov muag tsis pom kev.

2. Vim yog lub zog laser siab, kev ncaj qha irradiation ntawm cov laser txuas ntxiv yam tsis muaj kev kho mob sib txawv ntawm daim tawv nqaij thiab qhov chaw ntawm cov khaub ncaws tsaus yuav ua rau muaj zog thermal nyhuv, uas ua rau cov khaub ncaws hlawv thiab tawv nqaij scalding.

3. luv yoj (ultraviolet) laser, qhov no tsis yog ib qho teeb meem laser, tsis tsuas yog ultraviolet laser, tsuav nws yog ultraviolet lub teeb, nws yog tsim nyog los tiv thaiv, vim ultraviolet lub teeb yog ib chav kawm ntawm WHO-pom zoo carcinogens.

Dab tsi yog qhov yuav tsum tau tiv thaiv cov hluav taws xob laser thiab yuav tiv thaiv hluav taws xob laser li cas?

Ua ntej tshaj plaws, tsis muaj teeb meem thaum twg thiab nyob rau hauv dab tsi tshwm sim, tsis tuaj yeem siv laser irradiation ntawm tib neeg (txawm nws yog tus kheej lossis lwm tus) lossis tsiaj qhov muag, txhob txwm siv laser irradiation ntawm lwm lub qhov muag tuaj yeem raug txheeb xyuas tias yog kev ua txhaum cai raug mob, thiab yuav yog. raug txim txhaum cai!!

1. Yog tias kev sib cuag nrog laser (tsis yog kev ua haujlwm sib txawv), lub xeev muaj cov qauv tsim nyog rau kev faib cov laser:

•Class I (< 0.2mW) laser without special protection, because its output energy is low, the human body itself protection can prevent laser damage to the eyes (no one silly to shaking eyes uncomfortable also does not escape), this laser will not cause damage to the skin, so no special protection, this laser is more common in red laser pointer.

•Lub laser nruam saum Chav Kawm II yuav tsum hnav cov tsom iav tiv thaiv laser nrog cov wavelength sib thooj los tiv thaiv qhov muag. Piv txwv li, yog tias lub laser yog 532nm (lub teeb ntsuab), lub laser kev nyab xeeb tsom iav sib piv lub wavelength yuav tsum tau hnav, uas yog, lub tsom iav tiv thaiv rau 532nm. Kev tiv thaiv qib yog nyob ntawm lub zog tso zis laser. Class II thiab Class III laser tiv thaiv looj tsom iav nrog cov zis wavelength txiav tawm tus nqi ntawm OD4 tuaj yeem ua tiav cov txiaj ntsig kev tiv thaiv, tab sis tseem tsis tuaj yeem hnav tsom iav los saib ncaj qha ntawm lub laser.

• Kuj tseem muaj hom phaj iav uas yog tsim los ntawm cov khoom siv hu ua laser shield, uas tiv thaiv lub laser nrog rau cov ntaub thaiv npog laser, tab sis nrog thaj tsam loj dua.

•Class IV or above (>500mW) tsis tu ncua laser, nws yog qhov zoo tshaj plaws rau hnav cov tsom iav tiv thaiv laser nrog tib lub wavelength li laser tiv thaiv qib OD5 lossis siab dua. Tsis txhob hnav khaub ncaws tsaus nti thiab tsis txhob nthuav tawm koj cov tawv nqaij mus rau hluav taws xob laser.

2.Rau lub zog siab (Class IV) laser, hnav lub tsho dawb thaum ua haujlwm; Tsis txhob hnav cov watches thiab kub thiab nyiaj hniav nyiaj hniav kub, vim hais tias lawv tuaj yeem cuam tshuam lub teeb laser rau hauv lub qhov muag thiab ua rau muaj kev puas tsuaj. Nyob rau tib lub sijhawm, qhov muag yuav tsum tsis txhob hla lub laser tso zis qhov siab lossis taug kev ntawm qhov siab ntawm qhov tso zis laser; Thaum kawg ntawm txoj kev laser kho qhov muag kom tsis txhob muaj hluav taws kub hnyiab tau siv los tiv thaiv kev txuas ntxiv ntawm lub laser.

3. Rau ultraviolet / infrared laser, vim nws txoj kev pom tsis pom, txhua lub sijhawm tsis tuaj yeem saib lub qhov hluav taws xob (vim tias koj tsis paub tias nws puas nyob hauv lub teeb) Rau UV lasers, cov tawv nqaij yuav tsum tau muab tshuaj pleev thaiv hnub lossis tshuaj pleev thaiv hnub nrog. MPF tus nqi ntawm 50 lossis siab dua los tiv thaiv kev pheej hmoo ntawm kev mob qog noj ntshav ntawm daim tawv nqaij los ntawm UV teeb.

Cov saum toj no yog kev tiv thaiv ntawm "nruam laser", mem tes laser tiv thaiv kev ntsuas, tab sis feem ntau, tib neeg yuav tsis raug rau cov mem tes laser, txawm tias raug los kuj nyob rau hauv kev ua hauj lwm ntawm cov neeg ua hauj lwm, xws li photon chaw tshem tawm, photon whitening. cov no yog laser pulsed ncaj qha rau ntawm daim tawv nqaij, qhov xwm txheej no tsis tuaj yeem tiv thaiv tsis tas yuav tiv thaiv, Vim nws yuav tsis ua haujlwm, thiab nws yuav tsis ua mob rau koj. Txwv tsis pub, tsis tau tos koj los tiv thaiv, Kev Tswj Xyuas Khoom Noj thiab tshuaj hauv ntiaj teb yuav dhau mus, thiab kev kho mob laser ntawm myopia, uas yog laser ncaj qha rau hauv lub qhov muag, tab sis muaj ib tus kws kho mob ua haujlwm, yog li nws yuav tsis ua rau muaj kev puas tsuaj rau lub qhov muag. qhov muag.
