Laser kuajcov ntaub ntawv kev nyab xeeb
Nyob rau hauv xyoo tas los no, nrog kev txhim kho txuas ntxiv ntawm kev lag luam laser,laser tshuabtau dhau los ua ib feem ntawm kev tshawb fawb txog kev tshawb fawb, kev lag luam thiab lub neej.Rau cov neeg photoelectric koom nrog hauv kev lag luam laser, laser kev nyab xeeb yog ze ze rau lub chaw soj nstuam, kev lag luam thiab cov tib neeg, thiab tsis txhob muaj teeb meem laser rau cov neeg siv tau dhau los ua qhov tseem ceeb tshaj plaws.
A. Kev nyab xeeb theem ntawmlaser
Chav kawm 1
1. Class1: Laser hwj chim <0.5mW.Kev nyab xeeb laser.
2. Class1M: Tsis muaj teeb meem hauv kev siv ib txwm muaj.Thaum siv optical soj ntsuam xws li telescopes lossis tsom iav me me, yuav muaj kev phom sij tshaj li Class1 txwv.
Chav kawm 2
1, Class2: laser zog ≤1mW.Instantaneous exposure tsawg dua 0.25s muaj kev nyab xeeb, tab sis saib nws ntev dhau lawm tuaj yeem ua rau muaj kev phom sij.
2, Class2M: tsuas yog rau qhov muag liab qab tsawg dua 0.25s instantaneous irradiation muaj kev nyab xeeb, thaum siv telescopes los yog iav magnifying me me thiab lwm yam optical soj ntsuam, yuav muaj ntau tshaj li Class2 txwv tus nqi ntawm kev puas tsuaj.
Chav kawm 3
1, Class3R: laser zog 1mW ~ 5mW.Yog tias nws tsuas pom ib lub sijhawm luv luv xwb, tib neeg lub qhov muag yuav ua lub luag haujlwm tiv thaiv qee yam hauv kev tiv thaiv kev cuam tshuam ntawm lub teeb, tab sis yog tias lub teeb pom kev nkag mus rau tib neeg lub qhov muag thaum nws tsom, nws yuav ua rau tib neeg lub qhov muag puas tsuaj.
2, Class3B: laser zog 5mW ~ 500mW.Yog tias nws tuaj yeem ua rau lub qhov muag puas tsuaj thaum saib ncaj qha los yog xav txog, nws feem ntau muaj kev nyab xeeb los saib xyuas qhov sib txawv ntawm qhov sib txawv, thiab nws raug nquahu kom hnav cov tsom iav tiv thaiv laser thaum siv cov qib laser no.
Chav Kawm 4
Lub zog laser:> 500mW.Nws muaj kev phom sij rau lub qhov muag thiab tawv nqaij, tab sis kuj tuaj yeem ua rau cov ntaub ntawv nyob ze ntawm lub laser, ignite cov khoom siv hluav taws xob, thiab yuav tsum hnav cov tsom iav laser thaum siv cov qib laser no.
B. Ua phem thiab tiv thaiv laser ntawm qhov muag
Lub qhov muag yog qhov yooj yim tshaj plaws ntawm tib neeg lub cev rau laser puas.Ntxiv mus, cov teebmeem lom ntawm laser tuaj yeem sib sau ua ke, txawm tias ib qho kev raug mob tsis ua rau muaj kev puas tsuaj, tab sis ntau qhov kev cuam tshuam tuaj yeem ua rau muaj kev puas tsuaj, cov neeg raug tsim txom ntawm lub qhov muag rov ua dua laser feem ntau tsis muaj kev tsis txaus siab, tsuas yog xav tias qhov muag tsis pom kev.Laser lub teebnpog tag nrho cov wavelengths los ntawm ultraviolet mus rau deb infrared.Laser tiv thaiv iav yog ib hom tsom iav tshwj xeeb uas tuaj yeem tiv thaiv lossis txo cov laser puas 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 qhov zoo laser tsom iav?
1, tiv thaiv lub laser band
Txiav txim siab seb koj puas xav tiv thaiv tsuas yog ib lub wavelength los yog ob peb wavelengths ib zaug.Feem ntau cov tsom iav tiv thaiv laser tuaj yeem tiv thaiv ib lossis ntau lub wavelengths tib lub sijhawm, thiab kev sib txawv wavelength ua ke tuaj yeem xaiv cov iav tiv thaiv laser sib txawv.
2, OD: optical ceev (tus nqi tiv thaiv laser), T: transmittance ntawm kev tiv thaiv band
Laser tiv thaiv tsom iav tuaj yeem muab faib ua OD1 + rau OD7+ qib raws li qib kev tiv thaiv (qhov siab dua tus nqi OD, qhov kev ruaj ntseg siab dua).Thaum xaiv, peb yuav tsum tau them sai sai rau OD tus nqi qhia ntawm txhua lub tsom iav, thiab peb tsis tuaj yeem hloov tag nrho cov khoom tiv thaiv laser nrog ib lub lens tiv thaiv.
3, VLT: pom lub teeb transmittance (ambient teeb)
"Visible light transmittance" feem ntau yog ib qho ntawm cov tsis yooj yim ignored thaum xaiv laser tiv thaiv tsom iav.Thaum thaiv lub laser, daim iav tiv thaiv laser kuj tseem thaiv ib feem ntawm lub teeb pom kev, cuam tshuam rau kev soj ntsuam.Xaiv lub teeb pom kev zoo siab (xws li VLT> 50%) kom yooj yim saib xyuas qhov tshwm sim ntawm kev sim laser lossis laser ua;Xaiv lub teeb pom kev qis dua, tsim kom pom lub teeb pom kev yog lub sijhawm muaj zog heev.
Lus Cim: Lub qhov muag ntawm tus neeg teb xov tooj laser tsis tuaj yeem ncaj qha rau ntawm lub teeb laser lossis nws lub teeb pom kev zoo, txawm tias hnav cov iav tiv thaiv laser tsis tuaj yeem ntsia ncaj qha rau ntawm lub teeb (ntsig qhov kev taw qhia ntawm lub laser emission).
D. Lwm yam kev ceev faj thiab kev tiv thaiv
Laser reflection
1, thaum siv lub laser, cov kws sim yuav tsum tshem tawm cov khoom uas muaj qhov cuam tshuam (xws li watches, rings thiab paib, thiab lwm yam, yog qhov muaj zog xav tau) kom tsis txhob muaj kev puas tsuaj los ntawm lub teeb pom kev zoo.
2, laser curtain, lub teeb baffle, beam collector, thiab lwm yam., tuaj yeem tiv thaiv laser diffusion thiab stray reflection.Lub laser thaiv kev ruaj ntseg tuaj yeem kaw lub teeb laser nyob rau hauv ib qho chaw, thiab tswj lub laser hloov los ntawm lub laser thaiv kev ruaj ntseg los tiv thaiv laser puas.
E. Laser qhov chaw thiab kev soj ntsuam
1, rau infrared, ultraviolet laser beam pom tsis tau rau tib neeg lub qhov muag, tsis txhob xav hais tias lub laser tsis ua hauj lwm thiab lub qhov muag kev soj ntsuam, kev soj ntsuam, qhov chaw thiab kev soj ntsuam yuav tsum tau siv lub infrared / ultraviolet zaub card los yog soj ntsuam ntsuas.
2, rau cov fiber ntau txuas cov zis ntawm lub laser, tes tuav fiber ntau thwmsim, tsis tsuas yog yuav cuam tshuam rau cov kev sim thiab stability, tsis tsim nyog qhov chaw los yog khawb los ntawm lub fiber displacement, laser tawm kev taw qhia nyob rau tib lub sij hawm hloov, yuav kuj coj zoo. kev ruaj ntseg txaus ntshai rau cov neeg sim.Kev siv cov khoom siv kho qhov muag kho qhov muag kho qhov muag fiber ntau tsis tsuas yog txhim kho kev ruaj ntseg, tab sis kuj ua kom muaj kev nyab xeeb ntawm kev sim mus rau qhov zoo.
F. Tsis txhob muaj kev phom sij thiab poob
1. Nws yog txwv tsis pub muab cov khoom tawg yooj yim thiab tawg rau ntawm txoj kev uas lub laser hla.
2, lub zog siab tshaj plaws ntawm lub tshuab laser yog siab heev, uas yuav ua rau muaj kev puas tsuaj rau cov khoom siv sim.Tom qab lees paub qhov kev puas tsuaj ntawm cov khoom siv, qhov kev sim tuaj yeem zam qhov tsis tsim nyog poob ua ntej.
