    Germanium dị ka mono kristal nke a na-ejikarị eme ihe na ọkara-eduzi anaghị anabata ya na mpaghara 2μm ruo 20μm IR.A na-eji ya ebe a dị ka ngwa anya maka ngwa mpaghara IR.
    Germanium bụ ihe ndeksi dị elu nke a na-eji rụpụta Attenuated Total Reflection (ATR) prisms maka spectroscopy.Ya refractive index bụ ndị dị otú ahụ Germanium-eme ka irè eke 50% beamsplitter na-enweghị mkpa mkpuchi.A na-ejikwa Germanium eme ihe nke ukwuu dị ka ihe na-emepụta ihe nzacha anya.Germanium na-ekpuchi ihe niile nke 8-14 micron thermal band ma na-eji na lens usoro maka thermal onyogho.Enwere ike kpuchie Germanium AR na diamond na-emepụta optic n'ihu siri ike.
    A na-eto Germanium site na iji usoro Czochralski site na ọnụ ọgụgụ dị nta nke ndị nrụpụta na Belgium, USA, China na Russia.Ntụgharị ntụgharị nke Germanium na-agbanwe ngwa ngwa na ọnọdụ okpomọkụ na ihe ahụ na-aghọ ihe na-adịghị mma na ogologo oge ọ bụla dị ntakịrị karịa 350K ka ọdịiche nke band na-eju mmiri na electrons thermal.
