Igwe oghere chalcogenide maka ngwa infrared

Igwe oghere chalcogenide bụ oghere anya nke ejiri iko chalcogenide mee.Chalcogenide iko abụghị otu ma usoro nke iko dị ka amorphous ihe na-ebunye na infrared band.Ha gosipụtara ezi nnyefe (> 60%) na nso nke 2-12 micron, obere index nke refraction (2.4-2.8 @ 11micron), obere okpomọkụ mgbanwe na refractive index na ala mgbasa.Ha nwere ihe eji arụ ọrụ na ngwa anya na germanium, nke na-eme ka ha dabara nke ọma maka ngwa IR, ọkachasị na agba agba ya na oghere germanium na sistemụ ngwa anya.

N'adịghị ka germanium, nke kwesịrị ka e gwupụta ma nwee oke ọkọnọ, chalcogenide iko bụ sịntetik na ọnụ ahịa ha kwụsiri ike.Chalcogenide iko nwere ala gbazee ebe (200-400 ℃) ma e jiri ya tụnyere ndị ọzọ infrared ihe, ha nwere ike kpụrụ n'ime aspheric oghere na ọnụ ala maka nnukwu ibu mmepụta ("Igwe oghere chalcogenide kpụrụ akpụ IR”).Maka ihe abụọ a, oghere chalcogenide ga-arụ ọrụ dị mkpa na ngwa infrared.

Infrared wavelength nwere ike imepụta oghere chalcogenide dị iche iche nwere ụgbọ elu, concave, convex, aspheric and diffractive surfaces.Igwe chalcogenide kacha ewu ewu maka sistemụ na-arụ ọrụ na mpaghara 3-5 ma ọ bụ 8-12µm, yana mkpuchi mkpuchi na-atụgharị (AR mkpuchi), nkezi nnyefe nwere ike bute ruo 97.5-98.5% dabere na bandwit nke mkpuchi.Anyị nwekwara ike tinye diamond dị ka carbon mkpuchi (DLC mkpuchi) ma ọ bụ elu inogide mkpuchi (HD mkpuchi) n'elu oghere iji nyekwuo nchebe megide ọkọ na mmetụta.

Infrared wavelength na-arụpụta ezigbo okirikiri okirikiri na oghere enyo chalcogenide aspheric.Ha nwere ike ilekwasị anya ma ọ bụ gbanwee ọkụ ọkụ na-abata iji mezuo ihe achọrọ maka sistemụ infrared.Ngwa ahụ nwere ike ịbụ foto thermal, thermograph, beam collimating, spectrum analysis na wdg.
