Ihe eji eme iko Chalcogenide nke Lens Infrared a kpụchara akpụ

A na-egweri lensi infrared ọdịnala, na-eme ka ọ dị mma ma ọ bụ na-agbanwe ya ka ọ bụrụ elu ya, n'ikwu ya n'ụzọ ọzọ: site na "mmepụta oyi". Ọ bụ ezie na enwere ike ịmepụta lensi infrared site na "mmepụta okpomọkụ", ebe a anyị nwere lensi infrared nke ejiri ihe iko chalcogenide mee. Ịkpụzi lensi dabara adaba maka mmepụta buru ibu n'ihi na enwere ike ijikwa ọnụ ahịa mmepụta maka lensi ọ bụla ruo n'ọkwa dị ala. Lensi ndị a kpụrụ akpụ nwekwara ezigbo nguzozi ngwaahịa na mmepụta oke, nke na-eme ka usoro infrared dị mma.
Iko Chalcogenide abụghị otu kama ọ bụ usoro ihe dị ka iko amorphous nke a na-ebufe na eriri infrared. Anyị nwere ike ịhọrọ naanị ihe iko chalcogeni na ihe eji akpụzi lenzi infrared n'ihi obere ebe ha na-agbaze ma e jiri ya tụnyere ihe infrared ndị ọzọ.
Iko Chalcogenide nwere ezigbo ọsọ nnyefe (>60%) n'etiti 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 infrared, ọkachasị na nhazi agba site na iji germanium lens na sistemụ anya.
N'adịghị ka germanium nke a chọrọ igwu ma nwee obere ọkọnọ, ihe ndị e ji iko chalcogenide mee bụ ihe e ji aka mee. Ọnụ ahịa ha kwụsiri ike ma dịkwa mma. Lens e ji iko chalcogenide mee nwere ike ịbụ ezigbo ihe nnọchi anya lens germanium nke ha ga-arụ ọrụ dị mkpa karị na sistemụ infrared ọhụrụ e mere.

Infrared Wavelength nwere ike inye enyo infrared iko chalcogenide nke a kpụrụ akpụ nke nwere elu aspheric na diffractive. Lensi iko Chalcogenide kacha ewu ewu maka sistemụ na-arụ ọrụ na eriri infrared 3-5 micron ma ọ bụ 8-12 micron, nkezi nnyefe karịrị 97.5% yana mkpuchi anti-reflective (mkpuchi AR). Enwere ike itinye mkpuchi carbon dị ka diamond (mkpuchi DLC) ma ọ bụ mkpuchi siri ike (mkpuchi HD) na lensi infrared iko chalcogenide iji nye nchebe ọzọ megide ọkọ na mmetụta.
