Lens Gilashin Chalcogenide don Aikace-aikacen Infrared

Gilashin gilashin Chalcogenide ruwan tabarau ne na gani wanda aka yi da gilashin chalcogenide.Gilashin Chalcogenide ba ɗaya bane amma jerin gilashin kamar kayan amorphous waɗanda ake watsawa a cikin rukunin infrared.Sun ƙunshi watsawa mai kyau (> 60%) a cikin kewayon 2-12 micron, ƙananan index of refraction (2.4-2.8 @ 11micron), ƙananan canjin thermal a cikin ma'anar refractive da ƙananan watsawa.Suna da kayan aikin injiniya iri ɗaya da na gani zuwa germanium, wanda ke sa su dace da aikace-aikacen IR, musamman a cikin gyaran launi tare da ruwan tabarau na germanium a cikin tsarin gani.

Ba kamar germanium ba, wanda ke buƙatar hakowa kuma yana da ƙarancin wadata, gilashin chalcogenide na roba ne kuma farashin su ya fi karko.Gilashin Chalcogenide suna da ƙarancin narkewa (200-400 ℃) idan aka kwatanta da sauran kayan infrared, ana iya ƙera su cikin ruwan tabarau na aspheric tare da ƙarancin farashi don samarwa mai yawa (”Gilashin Gilashin Chalcogenide Molded IR-Molded”).Don waɗannan dalilai guda biyu, ruwan tabarau na chalcogenide zai taka muhimmiyar rawa a cikin aikace-aikacen infrared.

Infrared mai tsayi yana iya kera nau'ikan nau'ikan ruwan tabarau na chalcogenide tare da jirgin sama, concave, convex, aspheric da diffractive saman.Gilashin Chalcogenide ya fi shahara ga tsarin da ke aiki a cikin yanki na 3-5 ko 8-12µm, tare da suturar da ke da alaƙa (rufin AR), matsakaicin watsawa za a iya kawowa har zuwa 97.5-98.5% ya dogara da bandwidth na shafi.Hakanan zamu iya amfani da lu'u-lu'u kamar lu'u-lu'u kamar lu'u-lu'u (rufin DLC) ko babban rufi mai ɗorewa (HD shafi) akan saman ruwan tabarau don samar da ƙarin kariya daga karce da tasiri.

Wavelength infrared yana kera ingantattun sifofin al'ada da ruwan tabarau na gilashin chalcogenide na aspheric.Suna iya ko dai mayar da hankali ko kuma karkatar da haske mai shigowa don saduwa da takamaiman buƙatun tsarin infrared.Aikace-aikacen na iya zama hoto na thermal, thermograph, bim collimating, nazarin bakan da sauransu.
