Nrog rau kev siv dav dav ntawm semiconductor (diode) lasers hauv kev lag luam, kev kho mob zoo nkauj, thiab kev tshawb fawb tshawb fawb, kev ua haujlwm kev nyab xeeb tau dhau los ua qhov tseem ceeb uas tsis tuaj yeem lees paub. Lasers yog tus yam ntxwv los ntawm siab monochromaticity, muaj zog directionality, thiab coherence. Vim hais tias lawv lub zog yog cov concentrated, ncaj qha raug los yog specular reflection rau hauv lub qhov muag yuav ua rau irreversible retinal puas. Yog li ntawd, xaiv thiab siv kom rauglaser tsom iav kev ruaj ntsegyog ib qho kev ntsuas tseem ceeb rau kev tiv thaiv cov neeg ua haujlwm.
1. Core Parameters: Precise Matching nrog koj cov cuab yeej
Ua haujlwm Wavelength
Qhov sib txawv wavelengths ua rau ntau hom kev puas tsuaj ntawm lub qhov muag. Piv txwv li, pom thiab nyob ze - lub teeb infrared feem ntau ua rau lub retina puas, thaum lub teeb ultraviolet (UV) nyiam ua rau lub qhov muag thiab lub qhov muag raug mob. Thaum yuav khoom, koj yuav tsum paub meej txog qhov kev ua haujlwm wavelength ntawm koj lub diode laser (xws li, cov wavelengths xws li 450nm, 808nm, 980nm, lossis 1064nm). Cov hlua tiv thaiv ntawm cov looj tsom iav yuav tsum npog tag nrho qhov tshwj xeeb wavelength. Tsis txhob txiav txim siab tiv thaiv raws li xim lo ntsiab muag ib leeg- lo ntsiab muag tsaus nti tsis tas yuav thaiv UV rays, thiab cov lo ntsiab muag pob tshab tseem tuaj yeem thaiv cov kab hluav taws xob tshwj xeeb.
Optical Density (OD Tus Nqi)
Optical Density (OD) yog qhov ntsuas tseem ceeb rau kev ntsuas lub lens lub peev xwm los txo cov hluav taws xob laser. OD cov nqi nce logarithmically; txhua chav tsev nce txo qhov kev xa tawm los ntawm qhov zoo tshaj ntawm 10. Piv txwv li, OD 4 txo qhov teeb meem laser siv los ntawm 10,000 zaug, thaum OD 7+ txo nws los ntawm kaum tawm lab lub sij hawm. Koj yuav tsum xam qhov tsawg kawg nkaus yuav tsum tau OD raws li koj lub laser lub siab tshaj plaws tso zis zog los yog lub zog ceev. Txawm li cas los xij, nco ntsoov tias siab dua tsis yog ib txwm zoo dua. Cov txiaj ntsig OD ntau dhau ua rau txo qhov pom kev sib kis, ua rau pom kev tsis pom kev thiab muaj peev xwm cuam tshuam kev nyab xeeb thaum ua haujlwm raug.
Visible Light Transmission (VLT)
VLT txiav txim siab npaum li cas lub teeb ambient hla lub lens mus rau tus neeg hnav. Yog tias VLT poob qis dua 20%, yuav tsum muaj teeb pom kev ntxiv hauv qhov chaw ua haujlwm. Rau cov dej num uas yuav tsum tau ua kom siab -kev ua kom zoo los yog kev soj ntsuam, nws raug nquahu kom xaiv cov khoom nrog VLT ntawm 30% thiab 50%, ua kom muaj kev tiv thaiv txaus thaum tswj kev pom qhov pom tseeb.
2. Cov Khoom Siv & Kev Tsim Khoom: Kev txiav txim siab tiv thaiv thiab kav ntev
Laser kev nyab xeeblo ntsiab muag tam sim no poob rau hauv ob pawg tseem ceeb: cov iav iav thiab cov khoom siv polymer (xws li polycarbonate [PC] thiab acrylic [PMMA]).
Mineral Glass: Ua tiav kev tiv thaiv los ntawm doping tshwj xeeb absorbing cov ntaub ntawv rau hauv lub khob. Nws muaj qhov tshwj xeeb kub tsis kam thiab feem ntau siv rausiab -lub zog CO2 laser tiv thaiv.
Polycarbonate (PC): Piv rau acrylic, cov khoom siv PC boasts feem cuam tshuam rau ntau lub sij hawm siab dua, nrog rau Class B nplaim hluav taws xob -cov khoom retardant thiab superior tshuaj stability. Tam sim no nws yog qhov kev xaiv tseem ceeb rau kev hwmlaser tsom iav kev ruaj ntseg.
Tsis tas li ntawd, cov txheej txheem tsim khoom tau muab faib ua hom kev nqus thiab kev xav. Absorptive lo ntsiab muag siv cov dyes sab hauv kom nqus tau lub zog laser, muab kev nplij siab thiab tus nqi siab - ua tau zoo. Reflective lo ntsiab muag muaj cov txheej txheej dielectric uas thaiv lub teeb laser ntawm kev xav, ua rau lawv zoo tagnrho rau ntau - wavelength lossis ultra- siab- lub zog ib puag ncig.
3. Cov ntawv pov thawj & cov qauv: Cov kab hauv qab tiv thaiv cov khoom cuav
Raws li txoj cailaser tsom iav kev ruaj ntsegtsis yog looj tsom iav dub zoo tib yam; lawv yuav tsum nqa daim ntawv pov thawj kev nyab xeeb. Cov qauv kev lees paub thoob ntiaj teb suav nrog Asmeskas ANSI Z136 series thiab European CE EN 207 tus qauv. Hauv Suav teb, qhov sib npaug yog GB 30863-2014 (Cov cuab yeej tiv thaiv tus kheej - Qhov muag thiab ntsej muag tiv thaiv - Laser tiv thaiv). Cov khoom muaj tseeb yuav qhia meej meej txog qhov kev tiv thaiv wavelength ntau yam, OD tus nqi, thiab LB ntsuam xyuas (qhov kev puas tsuaj ntawm cov qauv hauv European qauv) ncaj qha rau ntawm tus ncej lossis lub lens. Tsis txhob muab cov khoom lag luam uas tsis muaj cim lossis tsis txaus ntseeg, vim tias lawv yuav ua tsis tau thaum koj xav tau ntau tshaj.
4. Cov lus qhia siv haum, xis, thiab nyab xeeb
Haum thiab Ergonomics
Vim tias lasers tuaj yeem tawg mus rau hauv lub qhov muag los ntawm ob sab, tsom iav yuav tsum muaj qhov haum. Designs featuring side shields yog pom zoo heev. Rau cov tib neeg uas hnav tsom iav tshuaj, saib rau Over-Lub- iav (OTG) tau tshaj dav thav duab, lossis xav txog kev cai tshuajlaser tsom iav kev ruaj ntseg. Cov ntaub qhwv qhov ntswg zoo thiab cov tuam tsev kho kom haum kuj tseem ceeb rau kev hnav ntev -.
Kev tu thiab hloov cov txheej txheem
- Ntxuav lo ntsiab muag siv xab npum me me thiab dej los yog cov tshuaj ntxuav tshwj xeeb; zam cov ntaub ntawv ntxhib los tiv thaiv khawb.
- Tsis txhob tso tsom iav kev nyab xeeb rau huab cua sov lossis lub hnub ci ncaj qha mus ntev los tiv thaiv cov khoom degradation.
- Tshawb xyuas cov lo ntsiab muag ua ntej txhua qhov kev siv rau khawb, tawg, lossis tawg. Thaum puas lawm, lub peev xwm tiv thaiv poob qis, thiab cov iav yuav tsum tau hloov tam sim ntawd.
- Txoj Cai Golden: Tsis txhob ntsia ncaj qha rau hauv lub teeb laser nyob rau hauv txhua qhov xwm txheej.tsom iav kev nyab xeebyog cov kab kawg ntawm kev tiv thaiv, tsis yog "dawb pass" kom nyab xeeb saib ncaj qha ntawm lub laser.
