Laser theem emit optical radiation-tab sis los ntawm alaser kev nyab xeebstandpoint, theem ntawm kev pheej hmoo nyob ntawm cov cuab yeej kev faib tawm, tso zis zog, thiab nws siv li cas. Kev nkag siab txog cov xwm txheej no yog qhov tseem ceeb rau kev ua haujlwm nyab xeeb hauv kev tsim kho, kev soj ntsuam, thiab kev siv dav dav.
Hom Radiation Emitted
Laser qib tsimtsis yog - ionizing hluav taws xobnyob rau hauv daim ntawv ntawmpom coherent teeb, feem ntau hauv covliab (630-670 nm)los yogntsuab (520-532 nm)wavelength ntau yam. Qhov no yogtsis yogionizing hluav taws xob (xws li X-rays lossis gamma rays) thiab tsis nqa lub zog txaus rau ib photon los ua kom puas DNA. Txawm li cas los xij, nws tseem tuaj yeem tsimqhov muag phom sijyog saib ncaj qha, tshwj xeeb tshaj yog nyob ze los yog rau lub sij hawm ntev.
Laser Safety Classification
Kev lees paub thoob ntiaj teblaser kev nyab xeebcov qauv-xws liIEC 60825-1: CovthiabANSI Z136.1- faib cov lasers raws li lawv lub peev xwm ua rau raug mob. Feem ntau cov kev sib tw thiab cov cuab yeej qib siab poob rau hauv ib qho ntawm ob qhov tsawg - pawg pheej hmoo:
表格
| Chav kawm | Maximum Output (Visible Light) | Laser Safety Risk | Kev Tiv Thaiv Tseem Ceeb |
|---|---|---|---|
| Chav kawm 2 | Tsawg dua lossis sib npaug li 1 milliwatt (mW) | Tsawg heev | Ntuj tib neeg aversion teb (blink reflex hauv 0.25 vib nas this) |
| Chav Kawm 3R | 1-5 mW | Tsawg rau nruab nrab | Kev raug mob tam sim no feem ntau muaj kev nyab xeeb; txhob txwm saib rau hauv kab teeb yuav tsum zam |
Cov kev faib tawm no raug muab rau thaum kuaj kev ua raws cai thiab yuav tsum tau cim kom meej meej ntawm lub cuab yeej.
⚠️ Laser Safety Note: Txawm tias Chav Kawm 2 thiab 3R cov cuab yeej tuaj yeem ua rau pom kev pom ib ntus (xws li, tom qab duab lossis qhov muag tsis pom kev) yog saib ncaj qha-tshwj xeeb tshaj yog cov lasers ntsuab, uas zoo li ci dua rau tib neeg lub qhov muag.
Kev xav tshwj xeeb: Infrared Radiation hauv Green Lasers
Qee cov khoom ntsuab -emitting li siv zaus-ob npaug tshuab uas muaj nyob rau hauvinfrared (IR) lasers(eg, 808 nm thiab 1064 nm). Yog tsis lim kom zoo,Tsis pom IR hluav taws xob tuaj yeem xauib sab ntawm lub teeb pom kev ntsuab.
Vim tias lub teeb IR tsis tuaj yeem pom, muajtsis muaj ntuj ntsais reflex, ua rau muaj kev pheej hmoo ntawm kev tsis pom kev raug. Cov cuab yeej muaj npe nrov suav nrog ua - hauv IR lim thiab tau txais kev lees paub kev nyab xeeb tag nrho. Nco ntsoov xyuas kom lub tsev ua tau raws li qhov tsim nyoglaser kev ruaj ntseg cov caithiab qhia cov ntawv pov thawj kom raug.
Yuav tsum muaj kev tiv thaiv qhov muag?
Raws li tsim laser kev ruaj ntseg cov lus qhia, tiv thaiv tsom iav yogtsis feem ntau yuav tsum taurau cov qauv siv Class 2 lossis Class 3R laser qib. Lawv tsim kom ntseeg tau tias cov emission siv tau nyob rau hauv qab noMaximum Permissible Exposure (MPE)txwv nyob rau hauv ib txwm ua haujlwm.
Txawm li cas los xij, kev tiv thaiv qhov muag yuav tsum xav txog thaum:
Ua haujlwm hauv ib puag ncig nrogReflective nto heev(piv txwv li, iav, polished hlau) ntawm qhov muag.
Ua cov haujlwm txuas ntxiv txuas ntxiv uas qhov kev sib tsoo ncaj qha muaj feem ntau dua.
Siv cov khoom siv uas tsis muaj cov ntawv qhia meej meej lossis cov cim kev ua raws cai.
Laser kev nyab xeebCov kev coj ua zoo tshaj plaws
Txhawm rau txo qhov pheej hmoo thiab tswj kom muaj kev nyab xeeb ua haujlwm ib puag ncig:
Tsis txhob saib ncaj qha rau hauv lub laser aperturelos yog raws txoj kab teeb.
Tsis txhob coj tus nqaj mus rau tib neeg, txawm luv luv.
Ua tib zoo xav txog qhov kev xav ntawm specularlos ntawm ci los yog mirrored nto.
Tshawb xyuas cov chav kawm laserthiab ua raws cov cim ua ntej siv.
Khaws cov khoom siv ruaj ntsegdeb ntawm cov neeg siv tsis tau tso cai, tshwj xeeb yog menyuam yaus.

Thaum cov qib laser feem ntau yog tsawg-kev pheej hmoo thaum siv kom raug, lawv tseem tso tawm cov hluav taws xob kho qhov muag uas poob rau hauv kev raug cailaser kev ruaj ntseg cov cai. Kev ua haujlwm nyab xeeb yog nyob ntawm kev nkag siab txog kev faib cov cuab yeej, ua raws li cov nqaj, thiab ua raws li kev ceev faj tseem ceeb.
Los ntawm kev ua raws li kev lees paub thoob ntiaj teblaser kev ruaj ntseg cov cai, cov neeg siv tuaj yeem ntseeg siab siv qhov tseeb ntawm cov cuab yeej laser alignment - yam tsis muaj kev cuam tshuam rau tus kheej lossis chaw ua haujlwm.
🔒 Kev Ceeb Toom Kawg: Hauvlaser kev nyab xeeb, kev paub thiab kev siv kom raug tseem ceeb tshaj li lub zog ib leeg. Ib txwm ua haujlwm nyob rau hauv cov qauv tsim thiab tsis txhob xav tias "tsawg zog" txhais tau tias "tsis muaj kev pheej hmoo."
