I-Germanium njenge-mono crystal esetshenziswa ngokuyinhloko ku-semi-conductor ayimunyi ezindaweni ezingu-2μm kuya kwezingu-20μm ze-IR.Isetshenziswa lapha njengengxenye ye-optical yezinhlelo zokusebenza zesifunda se-IR.
I-Germanium iyinkomba ephezulu esetshenziselwa ukukhiqiza amaprism e-Attenuated Total Reflection (ATR) e-spectroscopy.Inkomba yayo ye-refractive iwukuthi i-Germanium yenza i-beamsplitter yemvelo ephumelelayo engu-50% ngaphandle kwesidingo sokumbozwa.I-Germanium nayo isetshenziswa kakhulu njenge-substrate yokukhiqiza izihlungi ze-optical.I-Germanium imboza yonke ibhendi yokushisa engu-8-14 micron futhi isetshenziswa kumasistimu amalensi ekuthwebuleni okushisayo.I-Gerinium ingaba i-AR ihlanganiswe neDayimane ikhiqize i-optic yangaphambili eqinile kakhulu.
I-Germanium ikhuliswa kusetshenziswa indlela ye-Czochralski ngabakhiqizi abambalwa baseBelgium, e-USA, eChina naseRussia.Inkomba ye-refractive ye-Germanium ishintsha ngokushesha ngezinga lokushisa futhi okokusebenza kuba yi-opaque kuwo wonke amaza wamaza ngaphezudlwana kuka-350K njengoba igebe lebhendi ligcwala ama-electron ashisayo.
Isicelo:
• Ilungele izinhlelo zokusebenza eziseduze ne-IR
• I-Broadband engu-3 ukuya ku-12 μm ephikisana nokubukisa
• Ilungele izinhlelo zokusebenza ezidinga ukuhlakazeka okuphansi
• Ilungele izinhlelo zokusebenza ze-laser zamandla aphansi we-CO2
Isici:
• Lawa mawindi e-germanium awadluliseli endaweni eyi-1.5µm noma ngaphansi, ngakho-ke ukusetshenziswa kwawo okuyinhloko kusezifundeni ze-IR.
• Amafasitela e-Germannium angasetshenziswa ekuhloleni okuhlukahlukene kwe-infrared.
