    Qiyaasaha Farsamada

    Germanium-ka sida crystal mono-ka ugu horayn loo isticmaalo semi-conductor waa mid aan nuugeynin 2μm ilaa 20μm IR gobollada.Waxaa halkan loo isticmaalaa sidii qayb indhaha ah ee codsiyada gobolka IR.
    Germanium waa shay index sare ah oo loo isticmaalo in lagu soo saaro Attenuated Total Reflection (ATR) prisms ee spectroscopy.Its index refractive waa sida in Germanium ka dhigaysa dabiiciga ah wax ku ool ah 50% beamsplitter iyada oo aan baahida loo qabo daahan.Germanium sidoo kale waxaa si weyn loo isticmaalaa sida substrate soo saarista filtarrada indhaha.Germanium waxay dabooshaa guud ahaan 8-14 micron band thermal waxaana loo isticmaalaa hababka lenska ee sawirida kulaylka.Germanium waxa lagu dahaadhay AR oo leh dheeman soo saaraysa indho-indho hore oo aad u adag.
    Germanium waxaa lagu koray iyadoo la adeegsanayo farsamada Czochralski oo ay sameeyeen tiro yar oo warshado ah oo ku yaal Belgium, USA, Shiinaha iyo Ruushka.Tilmaanta refractive ee Germanium waxay si degdeg ah isu beddeshaa heerkulka, walxuhuna waxay noqdaan kuwo mugdi ku jiro dhammaan mawjadaha dhererka ee wax yar ka sarreeya 350K maaddaama farqiga u dhexeeya kooxdu ay daadanayaan elektaroonnada kulaylka.
    Codsiga:
    Ku habboon codsiyada IR-ku dhow
    • Broadband 3 ilaa 12 μm daahan ka-hortagga milicsiga
    Ku habboon codsiyada u baahan kala firdhin hoose
    • Ku fiican codsiyada laser CO2 awood hooseeya
    Tilmaam:
    Daaqadahan germanium-ka kuma gudbiyaan 1.5µm ama ka hooseeya, sidaa darteed codsigeeda ugu weyni waa gobolada IR.
    Daaqadaha Germanium waxaa loo isticmaali karaa tijaabooyin kala duwan oo infrared ah.
