Silicon Lens (Si lens) yeInfrared Application

Silicon lens is optical lens yakagadzirwa nesilicon.Silicon (Si) chinhu chine crystalline chinowanzo shandiswa mune infrared optical masisitimu anoshanda mu3 kusvika 5µm spectral band.Iyo refractive index iri padyo ne3.4 mukati mese.Iyo ine yakaenzana yakaderera densities pakati pezvakajairwa infrared zvinhu, inongori hafu yeGe, GaAs uye ZnSe.Saka silicon zvinhu yakanakira sarudzo kune system ine uremu zvinonetsa.Silicon zvakare yakaoma uye yakachipa kupfuura yakawanda yakajairika infrared zvinhu, dzikisa mutengo wezvinhu uchiwedzera mutengo wekugadzira panguva imwe chete.

Silicon yakanyatso kuenderana neMWIR application asi nekuda kwekunyura kwakasimba pamusoro pe6 micron, haina kufanirwa neLWIR application.Inogona zvakare kushandiswa segirazi substrate yelaser application nekuda kwekupisa kwayo, huremu huremu, uye kuoma.

Wavelength Infraredinogona kugadzira akasiyana chimiro chesilicon lens nendege, concave, convex, aspheric uye diffractive nzvimbo.Silicon inonyanya kufarirwa kune masisitimu anoshanda munharaunda ye3-5µm inotaridzika, ine anti-reflective coatings (AR coating), avhareji yekufambisa inogona kuunzwa kusvika 98%.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 infraredinogadzira mhando tsika spherical uye aspheric silicon lens.Ivo vanogona kutarisa kana kusiyanisa mwenje wemwenje unouya kuti usangane nezvinodiwa zveiyo infrared system.
