    Tapulaʻa faʻatekonolosi

    O le Germanium o se mono tioata faʻaaogaina masani i semi-avetaʻavale e le-mitiia i le 2μm i le 20μm IR itulagi. O loʻo faʻaaogaina ii o se optical vaega mo IR itulagi talosaga.
    Germanium o se maualuga index mea o loʻo faʻaaogaina e fausia ai Attenuated Total Reflection (ATR) prisma mo spectroscopy. O lona igoa faʻatonutonu e faʻapea o le Germanium e faia se mea aoga faʻapitoa 50% utupoto e aunoa ma le manaʻomia o coatings. O le Germanium o loʻo faʻaaoga faʻatele lava e avea o se substrate mo le gaosiga o filiga tioata. Germanium ufiufi le atoa o le 8-14 micron vevela faʻamau ma e faʻaaogaina i tioata faiga mo vevela atamamai. Germanium mafai ona AR coated ma Diamond faʻatupuina se matua sili ona faigata luma optic.
    Ua ola le Germanium i le faʻaaogaina o le Czochralski technique e se vaega toʻaitiiti o tagata gaosi oloa i Peleseuma, USA, Saina ma Lusia. O le faʻavasegaga faʻasino igoa o Germanium suia vave ma le vevela ma le mea avea opaque i uma wavelengthss laʻititi luga 350K a o le pa va vaʻa lolovaia faʻateletonika eletise.
    Talosaga:
    • Lelei tele mo lata-IR talosaga
    • Broadband 3 i le 12 μm aneti-toe teuteuina ufiufi
    • Lelei tele mo talosaga manaʻomia maualalo faʻasalalauina
    • Lelei tele mo le maualalo o le malosiaga CO2 laser laser
    Vaega:
    • O nei germanium faʻamalama e le lafoina atu i 1.5µm itulagi poʻo lalo, o le mea lea o lona autu faʻaaogaina o totonu o itulagi IR.
    • E mafai ona faʻaaogaina le faamalama o le Germanium i faʻataʻitaʻiga eseese o infrared.
