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.
