Lensi iko Chalcogenide maka ojiji infrared

Lensi iko Chalcogenide bụ lensi anya nke e ji iko chalcogenide mee. Iko Chalcogenide abụghị otu kama ọ bụ usoro ihe dị ka iko amorphous nke a na-ebufe na eriri infrared. Ha nwere ezigbo nnyefe (>60%) n'ogo nke 2-12 micron, obere index nke refraction (2.4-2.8@11micron), obere mgbanwe okpomọkụ na refractive index na obere mgbasa. Ha nwere ihe yiri nke germanium na ihe anya, nke na-eme ka ha dabara adaba maka ojiji IR, karịsịa na nhazi agba na lensi germanium na sistemụ anya.

N'adịghị ka germanium, nke a chọrọ igwupụta ma nwee obere ọkọnọ, iko chalcogenide bụ nke e ji aka rụọ, ọnụ ahịa ha na-akwụsikwa ike. Iko chalcogenide nwere obere ebe ịgbaze (200-400℃) ma e jiri ya tụnyere ihe ndị ọzọ e ji infrared mee, enwere ike ịkpụ ha ka ha bụrụ lensi aspheric na obere ọnụ ahịa maka mmepụta buru ibu (”)Lensi iko Chalcogenide nke IR-akpụ akpụ"). N'ihi ihe abụọ a, lenzi iko chalcogenide ga-arụ ọrụ dị mkpa karị na ngwa infrared.

Infrared Wavelength nwere ike imepụta ụdị dị iche iche nke lensi iko chalcogenide nwere elu dị larịị, concave, convex, aspheric na diffractive. Iko Chalcogenide kacha ewu ewu maka sistemụ na-arụ ọrụ na mpaghara spectral 3-5 ma ọ bụ 8-12µm, yana mkpuchi anti-reflective (mkpuchi AR), enwere ike iweta nnyefe nkezi ruo 97.5-98.5% dabere na bandwit nke mkpuchi ahụ. Anyị nwekwara ike itinye mkpuchi carbon dị ka diamond (mkpuchi DLC) ma ọ bụ mkpuchi siri ike (mkpuchi HD) n'elu lensi iji nye nchebe ọzọ megide ọkọ na mmetụta.

Ọ na-emepụta oghere infrared chalcogenide nke e ji agba gburugburu na nke aspheric mee nke ọma. Ha nwere ike ilekwasị anya ma ọ bụ gbanwee ìhè na-abata iji mezuo ihe achọrọ na sistemụ infrared. Ngwa a nwere ike ịbụ onyonyo okpomọkụ, thermograph, nhazi ihu igwe, nyocha spectrum na wdg.
