Er: YAG -Qhov Zoo Tshaj Plaws 2.94 Um Laser Crystal
Product Description
Txoj haujlwm no tshuaj xyuas cov kev qhia thiab cov txheej txheem rauEr: YOGlaser daim tawv nqaij resurfacing thiab hais txog lub luag hauj lwm ntawm pab neeg interprofessional hauv kev ntsuam xyuas thiab kho cov neeg mob uas undergo Er:YAG laser resurfacing ntawm daim tawv nqaij.
Er: YAG yog ib yam zoo heev 2.94 um laser siv lead ua, dav siv nyob rau hauv laser kho mob thiab lwm yam teb.Er: YOGsiv lead ua laser yog cov khoom siv tseem ceeb tshaj plaws ntawm 3nm laser, thiab txoj kab nqes nrog kev ua haujlwm siab, tuaj yeem ua haujlwm ntawm chav tsev kub laser, laser wavelength nyob rau hauv lub Scope ntawm tib neeg lub qhov muag kev nyab xeeb band, thiab lwm yam.
2,94 uaEr: YOGlaser tau dav siv nyob rau hauv kev kho mob kev phais, daim tawv nqaij zoo nkauj, kho hniav.Lasers powered los ntawm Er:YAG (erbium hloov: yttrium aluminium garnet), kev khiav hauj lwm ntawm 2.94 microns, crystals ob peb zoo rau hauv dej thiab lub cev kua. Qhov no yog tshwj xeeb tshaj yog pab tau rau daim ntaub ntawv nyob rau hauv lub teb ntawm laser tshuaj thiab kho hniav. Cov zis ntawm Er:YAG ua rau tsis muaj mob saib xyuas cov ntshav qab zib theem, thaum muaj kev nyab xeeb txo kev pheej hmoo kis mob. Nws kuj tseem zoo rau kev kho laser ntawm cov ntaub so ntswg, xws li tshuaj pleev ib ce resurfacing. Nws yog qhov zoo sib npaug rau kev kho cov ntaub so ntswg xws li cov hniav enamel.
Er: YAG nyiam qhov zoo dua li lwm cov khoom siv laser hauv 2.94 micron ntau yam uas nws ntiav YAG ua tus tswv tsev siv lead ua. Lub cev, thermal thiab optical zog ntawm YAG yog dav paub thiab nkag siab zoo. Laser tsim thiab cov tswv lag luam tuaj yeem siv lawv qhov tob ntawm kev paub nrog Nd:YAG laser tshuab kom ua tiav kev ua tau zoo ntawm 2.94 micron laser tshuab siv Er: YAG.
