Chaw kuaj mob lasercov ntaub ntawv kev nyab xeeb
Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho tas mus li ntawm kev lag luam laser,kev siv tshuab lasertau dhau los ua ib feem tseem ceeb ntawm kev tshawb fawb, kev lag luam thiab lub neej. Rau cov neeg ua haujlwm hauv kev lag luam laser, kev nyab xeeb ntawm laser muaj feem cuam tshuam nrog cov chaw soj nstuam, cov tuam txhab thiab cov tib neeg, thiab kev zam kev puas tsuaj rau cov neeg siv laser tau dhau los ua qhov tseem ceeb tshaj plaws.
A. Qib kev nyab xeeb ntawmlaser
Chav Kawm 1
1. Chav Kawm 1: Lub zog laser < 0.5mW. Lub laser muaj kev nyab xeeb.
2. Chav Kawm 1M: Tsis muaj kev phom sij rau kev siv li niaj zaus. Thaum siv cov khoom siv soj ntsuam xws li lub tsom iav lossis cov tsom iav me me, yuav muaj kev phom sij ntau dua li qhov txwv ntawm Chav Kawm 1.
Chav Kawm 2
1, Chav Kawm 2: lub zog laser ≤1mW. Kev raug hluav taws xob tam sim ntawd tsawg dua 0.25 vib nas this muaj kev nyab xeeb, tab sis saib nws ntev dhau tuaj yeem ua rau muaj kev phom sij.
2, Class2M: tsuas yog rau qhov muag liab qab tsawg dua 0.25 vib nas this instantaneous irradiation muaj kev nyab xeeb, thaum siv telescopes lossis iav me me thiab lwm yam optical soj ntsuam, yuav muaj ntau dua li qhov txwv Class2 ntawm kev puas tsuaj.
Chav Kawm 3
1, Class3R: lub zog laser 1mW ~ 5mW. Yog tias pom nws tsuas yog ib ntus xwb, lub qhov muag tib neeg yuav ua lub luag haujlwm tiv thaiv hauv kev tiv thaiv lub teeb, tab sis yog tias lub teeb nkag mus rau hauv lub qhov muag tib neeg thaum nws tsom mus rau, nws yuav ua rau lub qhov muag tib neeg puas tsuaj.
2, Chav Kawm 3B: lub zog laser 5mW ~ 500mW. Yog tias nws yuav ua rau lub qhov muag puas tsuaj thaum saib ncaj qha lossis cuam tshuam, feem ntau nws muaj kev nyab xeeb los saib qhov cuam tshuam diffuse, thiab nws raug pom zoo kom hnav cov tsom iav tiv thaiv laser thaum siv qib laser no.
Chav Kawm 4
Lub zog laser:> 500mW. Nws ua rau lub qhov muag thiab daim tawv nqaij puas tsuaj, tab sis kuj tuaj yeem ua rau cov khoom siv ze ntawm lub laser puas tsuaj, ua rau cov khoom kub hnyiab, thiab yuav tsum hnav cov tsom iav laser thaum siv qib laser no.
B. Kev puas tsuaj thiab kev tiv thaiv ntawm laser rau ntawm qhov muag
Lub qhov muag yog qhov tsis muaj zog tshaj plaws ntawm tib neeg lub cev rau kev puas tsuaj los ntawm laser. Ntxiv mus, cov teebmeem ntawm lub cev ntawm laser tuaj yeem sib sau ua ke, txawm tias ib qho kev raug mob tsis ua rau puas tsuaj, tab sis ntau qhov kev raug mob yuav ua rau puas tsuaj, cov neeg raug kev txom nyem los ntawm kev raug laser ntau zaus rau lub qhov muag feem ntau tsis muaj kev tsis txaus siab pom tseeb, tsuas yog hnov qhov muag poob qis.Lub teeb lasernpog txhua qhov wavelengths los ntawm ultraviolet heev mus rau infrared deb. Cov tsom iav tiv thaiv laser yog ib hom tsom iav tshwj xeeb uas tuaj yeem tiv thaiv lossis txo qhov puas tsuaj ntawm laser rau tib neeg lub qhov muag, thiab yog cov cuab yeej tseem ceeb hauv ntau yam kev sim laser.
C. Yuav ua li cas xaiv cov tsom iav laser zoo?
1, tiv thaiv cov laser band
Txheeb xyuas seb koj puas xav tiv thaiv tsuas yog ib qho wavelength lossis ntau qhov wavelengths ib zaug. Feem ntau cov tsom iav tiv thaiv laser tuaj yeem tiv thaiv ib lossis ntau qhov wavelengths tib lub sijhawm, thiab kev sib xyaw ua ke ntawm cov wavelengths sib txawv tuaj yeem xaiv cov tsom iav tiv thaiv laser sib txawv.
2, OD: optical density (laser tiv thaiv tus nqi), T: transmittance ntawm kev tiv thaiv band
Cov tsom iav tiv thaiv laser muaj peev xwm muab faib ua OD1 + txog OD7 + raws li qib kev tiv thaiv (OD tus nqi siab dua, kev ruaj ntseg siab dua). Thaum xaiv, peb yuav tsum tau them sai sai rau tus nqi OD uas tau qhia rau ntawm txhua khub tsom iav, thiab peb tsis tuaj yeem hloov tag nrho cov khoom tiv thaiv laser nrog ib lub lens tiv thaiv.
3, VLT: pom kev pom kev (lub teeb nyob ib puag ncig)
"Kev xa tawm lub teeb pom kev zoo" feem ntau yog ib qho ntawm cov kev ntsuas uas yooj yim tsis quav ntsej thaum xaiv cov tsom iav tiv thaiv laser. Thaum thaiv lub laser, daim iav tiv thaiv laser kuj tseem yuav thaiv ib feem ntawm lub teeb pom kev zoo, cuam tshuam rau kev soj ntsuam. Xaiv qhov xa tawm lub teeb pom kev zoo siab (xws li VLT> 50%) los pab txhawb kev soj ntsuam ncaj qha ntawm cov xwm txheej sim laser lossis kev ua laser; Xaiv qhov xa tawm lub teeb pom kev zoo qis dua, tsim nyog rau lub sijhawm pom kev muaj zog dhau.
Lus Cim: Lub qhov muag ntawm tus neeg teb xov tooj laser tsis tuaj yeem tsom ncaj qha rau lub teeb laser lossis nws lub teeb ci ntsa iab, txawm tias hnav daim iav tiv thaiv laser los tsis tuaj yeem saib ncaj qha rau lub teeb (ntsib qhov kev taw qhia ntawm lub teeb laser).
D. Lwm yam kev ceev faj thiab kev tiv thaiv
Kev cuam tshuam laser
1, thaum siv lub laser, cov neeg sim yuav tsum tshem tawm cov khoom uas muaj cov nplaim ci (xws li cov moos saib, cov nplhaib thiab cov cim, thiab lwm yam, yog cov chaw muaj zog ci ntsa iab) kom tsis txhob muaj kev puas tsuaj los ntawm lub teeb ci ntsa iab.
2, cov ntaub thaiv laser, lub teeb baffle, lub beam collector, thiab lwm yam, tuaj yeem tiv thaiv laser diffusion thiab distortion. Lub laser kev nyab xeeb shield tuaj yeem kaw lub laser beam hauv ib qho ntau yam, thiab tswj lub laser switch los ntawm laser kev nyab xeeb shield kom tiv thaiv laser puas tsuaj.
E. Kev teeb tsa laser thiab kev soj ntsuam
1, rau lub teeb infrared, ultraviolet laser beam tsis pom rau tib neeg lub qhov muag, tsis txhob xav tias lub laser tsis ua haujlwm thiab qhov muag saib, saib, tso thiab tshuaj xyuas yuav tsum siv daim npav infrared / ultraviolet lossis cov cuab yeej soj ntsuam.
2, rau cov fiber txuas nrog cov zis ntawm lub laser, tes tuav fiber kev sim, tsis yog tsuas yog yuav cuam tshuam rau cov txiaj ntsig kev sim thiab kev ruaj khov, qhov chaw tsis raug lossis khawb los ntawm kev hloov pauv fiber, laser tawm kev taw qhia tib lub sijhawm hloov pauv, kuj tseem yuav coj kev pheej hmoo loj rau cov neeg sim. Kev siv cov khoom siv fiber ntau los kho cov fiber ntau tsis yog tsuas yog txhim kho kev ruaj khov, tab sis kuj ua kom muaj kev nyab xeeb ntawm kev sim rau ntau yam.
F. Tsis txhob muaj kev phom sij thiab kev poob
1. Txwv tsis pub muab cov khoom uas yooj yim tawg thiab tawg rau ntawm txoj kev uas lub laser hla mus.
2, lub zog siab tshaj plaws ntawm lub laser pulsed yog siab heev, uas yuav ua rau puas tsuaj rau cov khoom sim. Tom qab paub meej tias qhov kev tiv thaiv kev puas tsuaj ntawm cov khoom, qhov kev sim tuaj yeem zam kev poob tsis tsim nyog ua ntej.
