Lenzi yegirazi yeChalcogenide yekushandisa infrared

Lenzi yegirazi yeChalcogenide igirazi re optical rakagadzirwa negirazi re chalcogenide. Girazi reChalcogenide harisi rimwe chete asi zvinhu zvakaita segirazi zvisina chimiro zvinotumirwa mu infrared band. Dzaive ne transmission yakanaka (>60%) iri pakati pe 2-12 micron, low index of refraction (2.4-2.8@11micron), low thermal change mu refractive index uye low dispersion. Dzakafanana ne germanium, izvo zvinoita kuti dzikwanise kushandiswa mu IR, kunyanya pakugadzirisa mavara ne germanium lens mu optical system.

Kusiyana negermanium, iyo inoda kucherwa uye ine huwandu hushoma, magirazi echalcogenide akagadzirwa uye mitengo yawo yakadzikama. Magirazi eChalcogenide ane poindi shoma yekunyunguduka (200-400℃) kana tichienzanisa nezvimwe zvinhu zveinfrared, anogona kuumbwa kuita lenzi yeaspheric nemutengo wakaderera kuti agadzire zvakawanda.Lenzi yegirazi yeChalcogenide yakaumbwa neIR"). Nekuda kwezvikonzero zviviri izvi, lenzi yegirazi yechalcogenide yaizotamba basa rakakosha mukushandiswa kweinfrared.

Wavelength Infrared inogona kugadzira magirazi egirazi echalcogenide ane chimiro chakasiyana-siyana chine plane, concave, convex, aspheric uye diffractive surfaces. Girazi reChalcogenide rinonyanya kufarirwa kune masisitimu anoshanda munzvimbo ye3-5 kana 8-12µm spectral, ine anti-reflective coatings (AR coating), avhareji yekutumira inogona kusvika 97.5-98.5% zvichienderana nebandwidth ye coating. Tinogona zvakare kuisa diamond-like carbon coating (DLC coating) kana high durable coating (HD coating) pamusoro pe lens kuti tipe dziviriro yakawedzerwa kubva pakukwenya nekugumburwa.

Wavelength infrared inogadzira lenzi dzegirazi dzemhando yepamusoro dzakagadzirwa nedenderedzwa neaspheric chalcogenide. Dzinogona kutarisa kana kusiyanisa chiedza chinouya kuti chisangane nezvinodiwa zve infrared system. Chishandiso chacho chingave thermal imaging, thermograph, beam collimating, spectrum analysis nezvimwewo.
