    Tawhā Hangarau

    Ko te Germanium hei karaihe mono e whakamahia tuatahihia ana ki te kaiarahi haurua-kore he ngongo-kore i te 2μm ki te 20μm rohe IR. Ka whakamahia i konei hei waahanga whika mo nga tono rohe IR.
    Ko te Germanium he taonga taupū teitei e whakamahia ana hei hanga i te Attenuated Total Reflection (ATR) prisma mo te spectroscopy. Ko tana taurangi reanga he penei i te mea ka hangaia e Germanium te 50% hihi maori anake me te kore e hiahiatia he paninga. Kei te whakamahia paitia a Germanium hei tira mo te hanga i nga taatari whatu. Ka kapi katoa a Germanium i te roopu waiariki 8-14 micron ka whakamahia ki nga punaha arotahi mo te whakaahua waiariki. Ka taea te whakakakahu i te Germanium me te Taimana e whakaputa ana i te ahua tino uaua o mua.
    Kei te whakatipuhia a Germanium ma te whakamahi i te tikanga Czochralski e te iti o nga kaihanga i Belgian, USA, China me Russia. Ko te taupū rehu o te Germanium ka tere rere ke me te paemahana ana ka korikori nga rauemi i nga roangaru katoa i runga ake i te 350K i te waipuke e pakaru ana te roopu me nga hiko hiko.
    Tono:
    • He pai mo nga tono tata-IR
    • Aratuku 3 ki te 12 μm paninga whakaata-whakaata
    • He pai mo nga tono tono iti te marara
    • He pai mo te mana iti CO2 tono laser
    Āhuahira:
    • Ko enei matapihi germanium kaore e tukuna i te 1.5µm rohe i raro ake ranei, no reira ko tana tono nui kei nga rohe IR.
    • Ka taea te whakamahi i nga matapihi Germanium i roto i nga momo whakamatautau pōkākā.
