Lub tsom iav laser laserTsis yog tsuas yog xim yas -lawv Heue yog qhov ntsuas pom ncaj qha ntawm qhov tseeb ntawm laser wavelengths lawv thaivCov. Xaiv cov xim tsis ncaj ncees lawm tuaj yeem tiv thaiv kev tiv thaiv tsis zoo, ua rau kev raug mob qhov muag. Cov lus qhia no tau txiav txim siab cov tswv yim, cov qauv, thiab cov xaiv xaiv tseem ceeb rau cov kws tshaj lij thoob ntiaj teb.
I. Tus Physics: Vim li cas lensol =}}}}} Wavelength
Kev tiv thaiv Laser vam khom rauxaiv lub teeb nqus dej lossis xav txog, tswj hwm los ntawm cov khoom science. XIM tawm los ntawm uas wavelengths yogthaivvs.kis.
1. Cov ntsiab lus (feem ntau)
Embedded Dyes nqus laser lub zog, hloov nws kom kub. Xim nyob ntawm zas xim cov qauv molecular:
| Lens xim | Lub Hom Phiaj Wavelength (NM) | Kev Sib Kis |
|---|---|---|
| Txiv kab ntxwv / Amber | 190-540 (xiav / ntsuab) | Txhim kho cov reds / yellows |
| Xim ntsuab | 600-700 (liab) | Zaub ntsuab, muaj kev nyuaj siab tsawg |
| Sib sib zog nqus liab | 800-1100 (NIR) | Sib sib zog nqus liab, blocks ir |
| Xim txho | Multi - wavelength | Nruab Nruab Nruab Nrab |
🔬 Daim Ntawv Teev Tseg: Ntxaum tints (piv txwv li, od 6+) nqus ntau lub zog tab sis txo qhov pom pom lub teeb kis tau (vlt). Tshaj kev txwv lub zog ua rauThermal Lensing(distortion) lossis txheej loj.
2. Reflective / Cuam Tshuam
Dielectric txheej qhia lasers ntawm nyias -} pa kev cuam tshuam. Cov xim tshwm xim nws yog xim hlau:
Kub: Xav txog 532nm (ntsuab) & 1064nM (ir)
Xiav - nyiaj: Block co₂ lasers (10,600nm)
⚠️ Kev pheej hmoo tseem ceeb: Txheeb xyuas cov teeb pom kev nyuaj theem nrab - tsis txhob siv cov neeg ua haujlwm ze uas tsis muaj.
Ii. Thaum kev xaiv xim ua rau tseem ceeb: 4 siab-} txoj kev pheej hmoo
1. Multi - laser ib puag ncig
Piv Txwv: Biotech (405Nm Diode + 1064 nd nd: yag)
Kev xaiv tsis ncaj ncees lawm: Cov ntsiab muag ntsuab (thaiv liab, xa tawm IR → ir IRLS Retina).
Lus teb:
Kev sivCov Ntxaij Lim Dej(xws li, txiv kab ntxwv txheej + grey sab hauv).
Tshawb xyuas dual daim ntawv pov thawj (piv txwv li, "Od7+}}}} {4 4}} @ 1064nm").
2. Precision pom cov haujlwm
Piv Txwv: Kev phais mob ophhalic (532nm laser + ntaub so ntswg sib txawv)
Kev xaiv tsis ncaj ncees lawm: Cov ntsiab lus liab liab (cov hlab ntshav qias neeg).
Lus teb:
Xaivsiab - sib piv daj (VLT >50%) nrog OD 4+ ntawm 532nm.
Xaiv cov coated polycarbonate - sib dua dua iav.
3. Siab - fais fab / pulsed lasers
Piv Txwv: Kev Txiav Txim (KW -} Chav Fiber Ntau)
Kev xaiv tsis ncaj ncees lawm: Absorptive nog lo ntsiab muag daj - yaj nyob rau hauv ncov zog ncov.
Lus teb:
Reflective gold coatings (handles >10 mw / cmo).
Pom zooMem Tes Nqi Ntsuas(NS / PS / FS).
4. Hom sib txawv ambient lub teeb
Piv Txwv: Kev Tu Sab Nraud Sab Nraud (905nm laser + hnub ci)
Kev xaiv tsis ncaj ncees lawm: Cov lo ntsiab muag zoo nkauj grey zoo nkauj heev thaum tsaus ntuj.
Lus teb:
Photochromic Lenses(xws li, adapts los ntawm OD3 rau OD7).
Auto - cov lim lim (ADF) muaj laser nrhiav kom tau.
III. Dhau xim: 5 tsis - txoj kev xaiv xaiv tau
OD Rating Xam
Cov lus ntawm ib txoj kab ke: OD yuav tsum=logo (tej hub fais fab density / mpe)
(Mpe=Daim Ntawv Tso Cai Tshaj Tawm Tshwj Xeeb Ib ANSI Z136.1)
Cov Qauv Ua Raws Cai
| Cheeb tsam | Lub hom phiaj | Daim Ntawv Pov Thawj |
|---|---|---|
| EU | EN 207: 2018 | CE + Wavelength / Teev # |
| Usa | ANSI Z87.1-2025 | "Z 87+" lub thwj |
Cov Khoom Siv Hluav Taws Xob
Polycarbonate: Kev Cuam Tshuam - Tsis kam, Hnav Khaub Ncaws (Zoo rau OD<6).
Lub khob: Qib OD ruaj khov, kos - tsis kam.
Peripheral tiv thaiv
Qhwv - nyob ib ncig ntawm cov qauv tsim block ntu reflections.
Goggle kaw rau UV / IR ib puag ncig.
Tej zaum siv tau yam siv tau
VLT (%) rau kev ua haujlwm clarity
Anti {- txheej txheej

IV. Cov Myths Tuag thiab Cov Lus
| Zaj dab neeg | Qhov tseeb | Lub txiv |
|---|---|---|
| "Tag nrho cov lenses liab thaiv IR" | Ib co tsuas thaiv 650nm, xa 800nm + | Retinal kub hnyiab |
| "Darker=muaj kev nyab xeeb" | Tshaj -} tsaus qhov ncauj qhov ncauj qhov ntswg tsis muaj tsw | Cuav kev ruaj ntseg |
| "Tsis Muaj Xim Lenses {{}} Tsis muaj kev tiv thaiv" | Clear dielectric Txheej thaiv thaiv IR / UV | Kev tsis muaj kev tiv thaiv raug |
🚨 Qhov Teeb Meem Tiag (2023): Tus kws tshawb fawb siv "Green" tsom iav nrog 1064nm laser kev txom nyem - tom qab kuaj sim od {}} ntawm 1064nm.
5-qib kev xaiv raws tu qauv
Tshuaj xyuas lasers: Sau tag nrho cov wavelengths, powers, pulse hom.
Xam OD: Siv OSHA / ANSI lub laij lej online.
Lim los ntawm cov qauv: Yuav tsum tau siv 207 lossis mil -} std-31000.
Ntsuam xyuas kev siv: Khij VLT, Qhov hnyav, thiab teb pom.
