Ihe mkpuchi infrared akpụziri chalcogenide Glass

A na-egweri oghere infrared ọdịnala, na-egbu maramara ma ọ bụ diamond ka ọ ghọọ elu ya, ya bụ: site na "ichepụta oyi".Ọ bụ ezie na enwere ike ịmepụta oghere infrared site na "ichepụta ọkụ", ebe a, anyị ejirila ihe iko chalcogenide kpụrụ akpụ.Mkpụzi oghere dabara adaba maka mmepụta nnukwu n'ihi na enwere ike ijikwa ọnụ ahịa a na-emepụta n'otu oghere n'ogo dị ala.Akpụkpọ anya anya m na-enwekwa nrụpụta ngwaahịa dị mma na mmepụta oke, nke na-eme ka ntụkwasị obi dị mma nke usoro infrared.
Chalcogenide iko abụghị otu ma usoro nke iko dị ka amorphous ihe na-ebunye na infrared band.Anyị nwere ike họrọ chalcogendie iko ihe na infrared lens ịkpụzi n'ihi na ha ala agbaze ihe tụnyere ndị ọzọ infrared ihe.
Chalcogenide iko nwere ezigbo nnyefe ọnụego (> 60%) na nso nke 2-12 micron, ala index nke refraction (2.4-2.8 @ 11micron), ala thermal mgbanwe na refractive index na ala dispersion.Ha nwere ihe eji arụ ọrụ na ngwa anya na germanium, nke na-eme ka ha dabara nke ọma maka ngwa infrared, ọkachasị na agba agba ya na oghere germanium na sistemụ ngwa anya.
N'adịghị ka germanium nke kwesịrị igwupụta ma nwee oke ọkọnọ, ihe chalcogenide enyo bụ sịntetik.Ọnụ ahịa ha kwụsiri ike na nke a na-anabata.Lens nke iko chalcogenide mere nwere ike bụrụ ezigbo nnọchi anya lens germanium nke ha ga-arụkwu ọrụ dị mkpa na sistemụ infrared ọhụrụ emebere.

Infrared wavelength nwere ike inye oghere infrared chalcogenide a kpụrụ akpụ nwere akụkụ aspheric na dị iche iche.Igwe oghere chalcogenide kacha ewu ewu maka sistemu na-arụ ọrụ na 3-5 micron ma ọ bụ 8-12 micron infrared band, nkezi nnyefe karịrị 97.5% na mkpuchi mkpuchi mkpuchi (AR mkpuchi).Ihe mkpuchi carbon dị ka diamond (ihe mkpuchi DLC) ma ọ bụ mkpuchi dị elu (HD mkpuchi) nwekwara ike tinye ya na oghere chalcogenide iko infrared iji nyekwuo nchebe megide ọkọ na mmetụta.
