Thaum 755nm laser siv rau ntawm daim tawv nqaij, ob qho tib si melanin thiab ntshav yuav nqus tau lub zog.Thaum xav txog qhov muaj zog nqus ntawm melanin los ntawm wavelength, peb tsis tuaj yeem tsis quav ntsej nws cov ntshav nqus, vim tias thaum ob leeg ntshav thiab melanin nqus tau, melanin tsis muaj qhov zoo sib piv.Vim tias ntshav tsis yog yam khoom uas peb xav tau, peb tsis xav kom cov ntshav nqus tau lub zog zoo heev, vim tias cov ntshav nqus tau lub zog zoo dua, lub zog ntau dua, nws yuav tsis ua haujlwm nrog melanin.
Lub zog nqus los ntawm cov khoom tsis yog lub hom phiaj (ntshav), ntxiv rau tag nrho cov khoom siv hluav taws xob yuav tsum tau ntxiv dag zog kom melanin tuaj yeem tau txais qee qhov kev txhawb nqa, tseem yuav ua rau muaj kev phiv tsis tsim nyog, xws li liab, subcutaneous hemorrhage, anti melanosis, thiab lwm yam. ., uas yuav ncua sij hawm rov qab los, tab sis kuj yuav ua rau muaj kev pheej hmoo ntawm kev phiv, xws li pigment nag lossis daus, anti melanosis thiab anti melanosis.
Yog li ntawd, qhov zoo dua lub zog nqus piv ntawm melanin txheeb ze rau cov ntshav, qhov kev sib tw tsawg dua ntawm hemoglobin, thiab cov nyhuv laser zoo dua.Qhov piv ntawm 755nm melanin rau cov ntshav nqus lub zog yog 50 npaug zoo dua, thaum qhov piv ntawm 1064nm melanin rau cov ntshav absorbed zog tsuas yog 16 npaug siab dua.Piv nrog rau 1064nm, nws cov nyhuv yog li 3 npaug zoo dua.
755nm wavelength: txaus nkag qhov tob
Thaum cov xwm txheej saum toj no tau ntsib, kev xaiv laser wavelength rau cov teeb meem ntawm daim tawv nqaij pigmented kuj tseem ceeb heev.Ntawd yog, qhov tob tob ntawm cov wavelengths mus rau ntawm daim tawv nqaij yuav tsum ncav cuag lub dermis kom zoo dua cov pigmented lesions los ntawm txheej superficial mus rau txheej tob ntawm daim tawv nqaij.
Txawm hais tias lub laser tawv nkag qhov tob ntawm nws lub wavelength tsis tau qhia meej meej, nws tsis yooj yim pom los ntawm qhov tob nkag mus rau lub wavelength ntau thiab sib txuas qhov tob tob ntawm qhov sib txawv wavelengths rau ntawm daim tawv nqaij hauv daim duab hauv qab no uas nws cov wavelength tuaj yeem nkag mus tau zoo. rau hauv daim tawv nqaij dermis, thiab tuaj yeem ua tiav cov txiaj ntsig zoo ntawm ntau yam pigmented lesions los ntawm epidermis mus rau dermis.
Haitai optoelectronic nti cov ntaub ntawv (pulse tam sim no, mem tes dav 50ms, repetition zaus 10Hz).Ua kom tiav 850 teev, uas yog, 30 lab pulses, ua tau raws li lub neej kev xav tau ntawm freckle tshem tawm thiab tshem tawm cov plaub hau daim ntawv thov ntawm 20 lab lub sij hawm.
Ntxiv rau 755nm wavelength, Qingdao Haitai Optoelectronics kuj tau tsim 780nm, 808nm, 880nm, 1064nm, 1470nm, 1550nm thiab lwm yam khoom siv tib lub raj rau kev kho mob kev zoo nkauj kev lag luam, uas tau txais kev pom zoo los ntawm kev lag luam.Tam sim no, lawv nyob rau hauv tus txheej txheem ntawm kev xa khoom loj.Cov neeg siv khoom txaus siab txais tos los tham.
