    O le Germanium e pei o se tioata mono e masani ona faʻaaogaina i le semi-conductor e le faʻaogaina i le 2μm i le 20μm IR itulagi.O lo'o fa'aaogaina iinei e fai ma vaega fa'apitoa mo fa'aoga o le itulagi IR.
    Germanium ose mea fa'asino maualuga lea e fa'aaogaina e gaosia ai le Attenuated Total Reflection (ATR) prisms mo spectroscopy.O lona fa'ailoga fa'asolosolo e pei o le Germanium e faia ai se 50% beamsplitter fa'anatura lelei e aunoa ma le mana'omia o ni fa'alavalava.Germanium e faʻaaogaina tele e fai ma mea e faʻaogaina ai le gaosiga o filiga mataʻutia.Germanium e ufiufi atoa le 8-14 micron thermal band ma e faʻaaogaina i tioata faʻapipiʻi mo ata vevela.Germanium e mafai ona faʻapipiʻiina AR i le Diamond e maua ai se mataʻutia pito i luma.
    Germanium ua faʻatupulaia e faʻaaoga ai le Czochralski technique e se vaega toʻaitiiti o tagata gaosi oloa i Peleseuma, ISA, Saina ma Rusia.O le faasino igoa o Germanium e vave ona suia i le vevela ma o le mea e avea opaque i soo se galu umi i luga aʻe laʻititi i luga ole 350K aʻo lolovaia le va i le eletise eletise.

    • Lelei mo talosaga latalata-IR
    • Alalaupapa lautele 3 i le 12 μm faʻapipiʻi faʻafefe
    • Lelei mo talosaga e manaʻomia le faʻasalalau maualalo
    • Lelei mo le maualalo o le mana CO2 leisa talosaga
    Vaega:
    • O nei fa'amalama germanium e le fa'asalalauina i le 1.5µm itulagi po'o lalo ifo, o lona uiga o lona fa'aoga autu o lo'o i totonu ole IR.
    • E mafai ona fa'aoga fa'amalama Germanium i fa'ata'ita'iga infrared eseese.
