Chalcogenide Girazi Lens yeInfrared Application

Chalcogenide girazi lens is optical lens yakagadzirwa nechalcogenide girazi.Chalcogenide girazi haisi imwe chete asi nhevedzano yegirazi senge amorphous zvinhu izvo zvinofambiswa mu infrared bhendi.Vairatidza kutapurirana kwakanaka (> 60%) muhuwandu hwe2-12 micron, yakaderera index yerefraction (2.4-2.8@11micron), yakaderera thermal shanduko mune refractive index uye yakaderera dispersion.Ivo vane zvakafanana mechanical uye optical zvimiro kune germanium, izvo zvinoita kuti vanyatsokodzera IR application, kunyanya mukugadziriswa kwemavara negermanium lens mune optical system.

Kusiyana negermanium, inoda kucherwa uye ine zvishoma, girazi rechalcogenide rinogadzirwa uye mitengo yavo yakagadzikana.Chalcogenide girazi ine yakaderera melt point (200-400 ℃) zvichienzaniswa nezvimwe infrared zvinhu, zvinogona kuumbwa kuita aspheric lens nemutengo wakaderera wekugadzira huwandu hukuru (”Yakaumbwa IR-Yakaumbwa Chalcogenide Girazi Lens”).Nezvikonzero zviviri izvi, chalcogenide girazi lens yaizotamba zvakanyanya uye zvakanyanya kukosha basa mune infrared application.

Wavelength Infrared inogona kugadzira akasiyana chimiro chechalcogenide girazi lens ine ndege, concave, convex, aspheric uye diffractive nzvimbo.Chalcogenide girazi inonyanya kufarirwa kune masisitimu anoshanda munharaunda ye3-5 kana 8-12µm inotaridzika, ine anti-reflective coatings (AR coating), avhareji yekufambisa inogona kuunzwa kusvika ku97.5-98.5% zvinoenderana nebandwidth yejasi.Isu tinogona zvakare kuisa madhaimondi-senge kabhoni coating (DLC coating) kana yakakwira yakasimba coating (HD coating) pane lens pamusoro kuti ipe imwe dziviriro kubva pakukwenya uye kukanganisa.

Wavelength infrared inogadzira mhando tsika spherical uye aspheric chalcogenide girazi lens.Ivo vanogona kutarisa kana kusiyanisa mwenje wemwenje unouya kuti usangane nezvinodiwa zveiyo infrared system.Chishandiso chacho chinogona kunge chiri chekupisa kufungidzira, thermograph, danda collimating, spectrum ongororo uye nezvimwe.
