Thaum ua haujlwm nrog xiav lasers, xaiv txoj caitsom iav kev nyab xeebyog qhov tseem ceeb los tiv thaiv qhov muag tsis pom kev puas tsuaj. Blue lasers ua haujlwm hauv lub435-480nm wavelength ntau, feem ntau siv nyob rau hauv siab -kev lag luam muaj tseeb xws li kev tsim khoom, khoom siv kho mob, thiab kev tshawb fawb txog kev tshawb fawb. Nkag siab txog lawv qhov kev pheej hmoo thiab yuav xaiv li caslooj tsom iavua kom muaj kev nyab xeeb ua haujlwm. Kab lus no piav qhia txog kev phom sij ntawm cov lasers xiav, yuav ua li cas xaiv cov tsom iav kev nyab xeeb tsim nyog, thiab qhov tseem ceeb ntawm cov xim lo ntsiab muag hauv kev tiv thaiv zoo.
Blue Laser yog dab tsi?
Ib lub laser xiav yog lub teeb ci sib xyaw ua ke emitting wavelengths ntawm435 nanometers (nm) thiab 480 nm, nrog cov zis ntau ntawm473nm ualos yog445nm ua. Cov lasers no yog cais raws liClass IIIa los yog siab duaraws li lawv lub zog tso zis, ua rau lawv muaj peev xwm ua rau muaj kev puas tsuaj yog tias mishandled. Tsis zoo li lub teeb pom kev, xiav lasers muaj lub zog siab ceev thiab luv luv wavelengths, uas yog qhov tshwj xeeb tshaj yog txaus ntshai rau tib neeg lub qhov muag.
Kev siv ntau yam ntawm Blue Lasers
Kev tsim khoom lag luam:
Cov lasers xiav yog siv rau vuam siab - cov khoom siv hluav taws xob zoo li tooj liab thiab txhuas vim lawv qhov kev nqus tau zoo dua piv rau infrared lasers. Lawv yog cov tseem ceeb hauv kev lag luam xws li kev tsim khoom semiconductor, automotive engineering, thiab roj teeb tsim.
Kev Tshawb Fawb Txog Kev Kho Mob thiab Kev Tshawb Fawb:
Hauv cov chaw kho mob, cov lasers xiav yog ua haujlwm rau kev phais kom raug thiab kuaj pom. Cov kws tshawb fawb siv lawv rau atomic cooling, fluorescence spectroscopy, thiab laser -induced breakdown spectroscopy (LIBS).
Kev kawm thiab Astronomy:
Tsawg-lub zog xiav laser pointers (473 nm) yog qhov nrov hauv cov chav kawm thiab kev ua yeeb yam stargazing rau qhov tseem ceeb ntawm cov khoom saum ntuj ceeb tsheej.
Consumer Electronics:
Blue lasers yog ib qho tseem ceeb rau Blu-ray disc technology thiab laser projectors.
Kev phom sij ntawm Blue Laser Exposure
Qhov luv luv wavelength thiab siab photon zog ntawm xiav lasers ua rau lawv tshwj xeeb txaus ntshai rau tib neeg lub qhov muag:
Retinal Burns: Kev raug ncaj qha-txawm tias qis- lub zog lasers (piv txwv li, 5 mW)- tuaj yeem ua rau lub qhov muag puas tas li. Lub retina tsis muaj qhov mob receptors, yog li kev raug mob yuav mus tsis tau pom txog thaum tsis pom kev tshwm sim.
Phototoxicity: Ntev ntev ua rau muaj kev pheej hmoo ntawm macular degeneration thiab cataracts.
Kev tshwm sim tshwm sim: Glare los ntawm qhov chaw muaj kev cuam tshuam (piv txwv li, hlau, iav) tseem tuaj yeem xa lub zog tsis zoo rau lub qhov muag.
Menyuam yaus Vulnerability: Cov menyuam yaus muaj kev pheej hmoo siab dua vim tias lawv cov lo ntsiab muag xa cov teeb xiav ntau dua yam tsis muaj kev lim dej.
Yuav ua li cas xaiv Blue Laser Safety Glasses
Kev xaiv cov tsom iav kev nyab xeeb zoo suav nrog kev ntsuas peb yam tseem ceeb:
Kev Pabcuam Wavelength:
Xyuas kom cov iav thaiv qhov tshwj xeeb xiav laser wavelength koj ua haujlwm nrog (xws li, 473 nm lossis 445 nm). Kev tiv thaiv overlapping hla lub wavelengths uas nyob ib sab kuj tseem ceeb rau ntau - laser ib puag ncig.
Optical Density (OD):
OD ntsuas lub lens lub peev xwm los ua kom lub zog laser. Piv txwv li:
Class IIIa lasers(Less tshaj los yog sib npaug rau 5 mW): OD Ntau tshaj los yog sib npaug rau 2.
Class IIIb/IV lasers (>5 mW): OD Ntau dua lossis sib npaug ntawm 5-7.
Cov txiaj ntsig OD siab dua qhia tias muaj kev tiv thaiv ntau dua rau cov lasers muaj zog.
Kev Ua Raws Cai:
Nrhiav daim ntawv pov thawj hauv qabTS EN ISO 166los yogANSI Z87.1, uas qhia meej mechanical durability, optical clarity, thiab cuam tshuam tsis kam. Rau European kev lag luam,EN 207: 2017yog tus qauv kub raulaser qhov muag tiv thaiv.
Lub Lens yuav tsum yog xim dab tsi?
Lub lens xim nyob ntawm qhov kho qhov muag lim tshuab:
Yellow lossis Amber Tint: Cov lo ntsiab muag no zoo tshaj plaws rauxiav laser tiv thaiv. Lawv nqus tau luv luv -yoj xiav lub teeb (415–455 nm) siv cov ntsiab lus xim ntxiv. Lub amber tint ua kom pom kev pom thaum thaiv teeb meem wavelengths.
Ntshiab lossis Lub Teeb Yellow Lenses: Tsim nyog rau qis - lub zog lasers (Class IIIa) qhov xav tau tsawg kawg nkaus. Txawm li cas los xij, cov no muaj kev txo qis rau siab dua - lasers zog.
Zam cov khoom cuav: Qee cov iav cuav siv cov xim cuav uas tsis muaj kev pom zoo. Nco ntsoov xyuas covxiav lub teeb thaiv tus nqi(60–70% yog ib qho zoo rau 473 nm) thiab tshawb xyuas qhov thib peb -cov ntaub ntawv kuaj xyuas tog.
Kev txiav txim siab tseem ceeb rau Kev Siv Lub Sij Hawm Ntev -
Kev nplij siab thiab haum: Ib qho kev ruaj ntseg, adjustable thav duab tiv thaiv lub tsom iav los ntawm slipping thaum lub sij hawm txav. Cov khoom siv hnyav txo qhov qaug zog thaum siv txuas ntxiv.
Durability: Anti-cov coatings khawb thiab cuam tshuam- cov thav ntawv tiv thaiv kom cov iav tiv taus hnav txhua hnub hauv cov chaw lag luam.
Pom kev: Pom pom lub teeb pom kev siab (30–80%) tswj qhov pom tseeb tsis ua rau qhov muag tsis pom kev.
Xaus: Ua ntej kev nyab xeeb nrog kev pov thawj pov thawj
Blue lasers yog cov cuab yeej muaj zog, tab sis lawv cov kev pheej hmoo xav tau kev ntsuas kev nyab xeeb. Ib txwm hnav tsom iav kev ruaj ntseg uas phim koj lub laser lub wavelength thiab lub zog. Rau kev txhim khu kev qha, EN 207-raws li kev daws teeb meem,JTBYShield's laser tsom iav kev nyab xeebyog tsim los ua kom tau raws li cov qauv thoob ntiaj teb, muab cov kev kho qhov muag pom tseeb, kev tsim kho ruaj khov, thiab pom kev pom zoo. Kev nqis peev hauv siab - kev tiv thaiv zoo los tiv thaiv koj lub zeem muag thiab xyuas kom ua raws li txhua daim ntawv thov.
