    I-Germanium njenge-mono crystal esetshenziswa kakhulu kuma-semi-conductor ayibambi kakhulu ezifundeni ze-2μm kuya ku-20μm IR. Isetshenziswa lapha njengengxenye ye-optical yezinhlelo zokusebenza zesifunda se-IR.
    I-germanium iyinto yenkomba ephezulu esetshenziselwa ukukhiqiza ama-prism we-spectroscopy we-Attenuated Total Reflection (ATR). Inkomba yayo yokubonisa ifana nokuthi iGermanium yenza i-beamsplitter yemvelo esebenzayo ngempumelelo ngaphandle kwesidingo sokumbozwa. IGermanium isetshenziswa kakhulu njenge-substrate yokukhiqiza izihlungi ze-optical. IGermanium ihlanganisa lonke ibhande elishisayo le-8-14 micron futhi isetshenziswa ezinhlelweni zelensi zokucabanga okushisayo. IGermanium ingafakwa i-AR ngeDayimane ekhiqiza i-front optic enzima ngokweqile.
    IGermanium itshalwa kusetshenziswa inqubo yeCzochralski ngenani elincane labakhiqizi eBelgium, eU.SA, eChina naseRussia. Inkomba ekhombayo yeGermanium ishintsha ngokushesha ngamazinga okushisa futhi okokusebenza kuba opaque kuwo wonke ama-wavelengths ngaphezulu kwe-350K njengoba igebe le-band ligcwala ngama-electron ashisayo.
    Isicelo:
    • Ilungele izinhlelo eziseduze ne-IR
    • I-Broadband 3 kuye ku-12 μm yokulwa nokubonisa
    • Ideal for izicelo ezidinga ukuhlakazeka low
    • Kuhle kakhulu ekusetshenzisweni kwamandla we-CO2 laser
    Isici:
    • Lawa mawindi we-germanium awadlulisi esifundeni esingu-1.5µm noma ngezansi, ngakho-ke isicelo sawo esiyinhloko sisezindaweni ze-IR.
    • Amafasitela weGermanium angasetshenziswa ekuhlolweni okuhlukahlukene kwe-infrared.
