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 wax ku ool ah dabiiciga ah 50% beamsplitter iyada oo aan baahida loo qabo daahan.Germanium sidoo kale waxaa si weyn loogu isticmaalaa sidii substrate soo saarista filtarrada indhaha.Germanium waxay dabooshaa guud ahaan 8-14 micron band thermal band waxaana loo isticmaalaa hababka muraayadaha sawirada 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 dib-u-celinta ee Germanium waxay si degdeg ah isu beddeshaa heerkulka, walxuhuna waxay noqdaan kuwo mugdi ah dhammaan mawjadaha dhererka ee wax yar ka sarreeya 350K maaddaama farqiga kooxdu uu daadiyo 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 tijaabooyinka infrared ee kala duwan.
