    The Germanium dị ka a mono kristal mbụ na-eji na ọkara eduzi bụ ndị na-abụghị absorptive na 2μm ka 20μm Iye mpaghara. A na-eji ya ebe a dị ka ngwa anya maka ngwa mpaghara mpaghara IR.
    Germanium bụ ihe ndekpọ dị elu nke a na-eji emepụta Prisms Attenuated Total Reflection (ATR) maka spectroscopy. Ntughari ntughari ya di ka Germanium na eme ihe oma nke oma 50% nke n’enweghi nkpuchi. A na-ejikwa Germanium n'ọtụtụ ebe dị ka mkpụrụ maka imepụta ngwa ngwa ngwa. Germanium na-ekpuchi bandị nke igwe ọkụ 8-14 micron ma jiri ya na sistemụ lens maka ntanetị ọkụ. Germanium nwere ike AR ntekwasa na Diamond amị ihe siri nnọọ ike n'ihu optic.
    Germanium toro site na iji usoro Czochralski site na ọnụ ọgụgụ dị nta nke ndị nrụpụta na Belgium, USA, China na Russia. Ntughari ihe na-agbanwe agbanwe nke Germanium na-agbanwe ngwa ngwa na ogo na ihe a na-aghọ ihe ocha mgbe niile na-agbatị ntakịrị ntakịrị karịa 350K dị ka ide mmiri idei mmiri na electrons thermal.
