Lens na Germanium (Ge lens) don Aikace-aikacen Infrared

ruwan tabarau na Germanium ruwan tabarau ne na gani wanda aka yi da germanium.Germanium (Ge) abu ne na crystalline tare da mafi girman ma'anar refractive (4.002@11µm) na kayan infrared da aka saba amfani da su.Hakanan yana da ƙarancin tarwatsawa, babban tauri da yawa.Saboda kewayon watsawa mai faɗi (sama da 45% a cikin 2-12 micron band) kuma bayyanuwa ga UV da haske mai gani, Germanium ya dace da aikace-aikacen IR kamar tsarin hoto na thermal, aikace-aikacen filin infrared da ainihin kayan aikin nazari.

Germanium kuma yana ƙarƙashin guduwar zafi.Tare da girma yawan zafin jiki, sha yana ƙaruwa da sauri.Saboda wannan sakamako na gudu na thermal, ruwan tabarau na germanium bai dace da amfani da shi ba a yanayin zafi sama da 100°C.

Infrared mai tsayi yana iya kera nau'ikan nau'ikan ruwan tabarau na germanium tare da jirgin sama, concave, convex, aspheric da filaye daban-daban.Germanium ya fi shahara ga tsarin da ke aiki a cikin yanki na 3-5 ko 8-12µm, tare da suturar da ke da kariya (rufin AR), ana iya kawo matsakaicin watsawa har zuwa 97.5-98.5% ya dogara da bandwidth na rufin.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 ƙera ingantattun nau'ikan sifofi na al'ada da ruwan tabarau na germanium 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.
