UV Laser yam ntxwv thiab kev nyab xeeb

Ultraviolet laser yog tau los ntawm triple zaus los yog zaus ob npaug ntawm lub teeb infrared. Nyob rau hauv xyoo tas los no, ultraviolet laser tau tsim sai heev, nrog kev loj hlob txhua xyoo ntawm ntau tshaj 15 feem pua. Tam sim no, lub ntsiab ultraviolet laser wavelengths yog 266nm thiab 355nm, thiab tam sim no lub 355nm laser nyob rau hauv domestic industrial teb tau tsim heev maturely nyob rau hauv nanosecond ultraviolet lasers, thiab lub hwj chim yuav ncav cuag ntau tshaj 10 watts.

Ultraviolet laser muaj ntau yam zoo, xws li luv luv wavelength, siab photon zog concentration, yooj yim nqus los ntawm cov ntaub ntawv, nqaim mem tes dav, siab daws teeb meem, ceev ceev ntawm lub teeb, thiab tshwj xeeb tshaj yog muaj cov cuab yeej ntawm "txias ua" (tsis muaj sab nraud cua sov ntawm cov txheej txheem. qhov chaw). Yog li ntawd, nws yog dav siv nyob rau hauv kev ua cov ntaub ntawv hloov tau yooj yim thiab nyob rau hauv cov tshuaj laser.

Tab sis tib lub sijhawm, nws yog qhov tseeb vim qhov luv wavelength thiab siab photon zog ntawm ultraviolet lub teeb uas ultraviolet lub teeb kuj muaj qee yam phom sij. Cov teeb meem feem ntau yog kev puas tsuaj rau lub cornea thiab daim tawv nqaij:

1. raug ultraviolet lub teeb rau lub sij hawm ntev los yog raug rau high-zog ultraviolet lub teeb nyob rau hauv ib lub sij hawm ntawm lub sij hawm, qhov ntau ntawm qhov muag kab mob yog electro-optic ophthalmia, lub ntsiab tshwm sim yog liab thiab o ntawm lub qhov muag, tearing, dryness thiab photophobia, lub hauv paus ntsiab lus qab nws yog Corneal epithelial hlwb thiab conjunctiva nqus ib tug loj npaum li cas ntawm muaj zog ultraviolet lub teeb, uas ua rau diffuse punctate tsis nyob rau hauv lub pob txha epithelium ntawm lub qhov muag, uas yuav ua rau myopia, cataract thiab glaucoma nyob rau hauv lub sij hawm ntev;

2. Kev puas tsuaj ntawm daim tawv nqaij kuj muaj ntau heev nyob rau hauv lub neej niaj hnub, xws li cov tawv nqaij pigmentation (tawv nqaij darkening), daim tawv nqaij thickening thiab roughening, daim tawv nqaij photoaging tshwm sim los ntawm lub sij hawm ntev ntawm daim tawv nqaij raug rau ultraviolet rays, thiab mob hnyav tej zaum yuav ua rau mob. , mob qog noj ntshav thiab lwm yam.

Yog li ntawd, kev tiv thaiv kev nyab xeeb ntawm ultraviolet laser yog qhov tseem ceeb dua. Vim tias ultraviolet laser muaj ob qho tib si cov yam ntxwv ntawm laser thiab ultraviolet lub teeb, lub zog siab dua thiab muaj zog ntau dua li lub teeb ultraviolet zoo tib yam, thiab cov hluav taws xob puas rau ntawm daim tawv nqaij thiab qhov muag kuj ntau dua. Yog li ntawd, nyob rau hauv qhov chaw ua hauj lwm ntawm lub zog ultraviolet lub teeb thiab ultraviolet laser, cov kws tshaj lij ultraviolet laser tiv thaiv iav yuav tsum tau hnav.
