Er: YAG -Yakanakisa 2.94 Um Laser Crystal
Product Description
Ichi chiitiko chinoongorora zviratidzo uye nzira yeEr:YAGlaser ganda resurfacing uye rinoratidza basa reboka renyanzvi mukuongorora nekurapa varwere vanopinda Er: YAG laser resurfacing yeganda.
Er: YAG imhando yeakanakisa 2.94 um laser crystal, inoshandiswa zvakanyanya mulaser medical system uye mamwe minda.Er: YAGcrystal laser ndiyo inonyanya kukosha zvinhu zve3nm laser, uye mutsetse unoshanda zvakanyanya, unogona kushanda pakamuri tembiricha laser, laser wavelength iri mukati mechikamu chebhendi rekuchengetedza ziso remunhu, nezvimwe.
2.94 umEr: YAGLaser yakashandiswa zvakanyanya mukuvhiya munharaunda yezvokurapa, kunaka kweganda, kurapwa kwemazino.Lasers powered by Er:YAG (erbium substituted: yttrium aluminium garnet), inoshanda pa 2.94 microns, makristasi akaroorana zvakanaka mumvura uye mvura yemuviri. Izvi zvinonyanya kubatsira kune maapplication muminda ye laser mushonga uye dentistry. Kubuda kweEr: YAG inogonesa kutarisisa kusingarwadze kwemazinga eshuga yeropa, uku ichidzikisa zvakachengeteka njodzi yehutachiona. Inoshandawo pakurapa kwelaser yezvinyoro zvinyoro, senge cosmetic resurfacing. Inobatsira zvakaenzana pakurapa matishu akaoma sezino enamel.
Er: YAG inonakidzwa nemukana pamusoro pemamwe makristasi e-laser mune iyo 2.94 micron renji pakuti inoshandisa YAG sekristaro inotambira. Iyo yemuviri, yekupisa uye yemaziso zvimiro zveYAG zvinozivikanwa zvakanyanya uye zvinonzwisiswa. Vagadziri veLaser uye vanoshanda vanogona kushandisa kudzika kwavo kweruzivo neNd: YAG laser masisitimu kuti vabudirire kuita kwepamusoro kubva ku2.94 micron laser masisitimu vachishandisa Er: YAG.
