    Germanium ngati mono crystal yomwe imagwiritsidwa ntchito kwambiri mu semi-conductor simayamwa m'magawo a 2μm mpaka 20μm IR.Amagwiritsidwa ntchito pano ngati gawo la kuwala kwa IR dera ntchito.
    Germanium ndizomwe zimagwiritsidwa ntchito popanga ma prisms a Attenuated Total Reflection (ATR) a spectroscopy.Refractive index yake ndi yakuti Germanyium imapanga 50% beamsplitter yachilengedwe popanda kufunika kwa zokutira.Germanium imagwiritsidwanso ntchito kwambiri ngati gawo lapansi popanga zosefera za kuwala.Germanium imakwirira gulu lonse la 8-14 micron thermal band ndipo imagwiritsidwa ntchito pamakina a lens pakuyerekeza kwamafuta.Germanium itha kukhala AR yokutidwa ndi Diamondi kutulutsa mawonekedwe olimba kwambiri akutsogolo.
    Germanium imakula pogwiritsa ntchito njira ya Czochralski ndi ochepa opanga ku Belgium, USA, China ndi Russia.Mlozera wa refractive wa Germanium umasintha mofulumira ndi kutentha ndipo zinthuzo zimakhala zosaoneka bwino pamafunde onse kupitirira 350K pamene kusiyana kwa gulu kumasefukira ndi ma elekitironi otentha.
    Ntchito:
    • Zabwino kwa mapulogalamu apafupi ndi IR
    • Broadband 3 mpaka 12 μm anti-reflection zokutira
    • Abwino ntchito amafuna otsika kubalalitsidwa
    • Zabwino kwa otsika mphamvu CO2 laser ntchito
    Mbali:
    • Mazenera a germanium awa samafalikira kudera la 1.5µm kapena pansi, chifukwa chake ntchito yake yayikulu ili m'magawo a IR.
    • Mawindo a Germanynium angagwiritsidwe ntchito poyesera zosiyanasiyana za infrared.
