    Cov Kev Kawm Siv Tau

    Lub Germanium raws li cov mono siv lead ua feem ntau siv nyob rau hauv semi-conductor yog tsis-haum ntawm 2μm rau 20μm IR thaj tsam. Nws yog siv ntawm no ua qhov khoom siv kho qhov muag rau IR cheeb tsam kev siv.
    Germanium yog cov khoom siv siab zog uas tau muab coj los ua Attenuated Total Reflection (ATR) prisms rau spectroscopy. Nws qhov ntsuas qhov ntsuas tsis tau zoo yog qhov tias Germanium ua qhov ua tau zoo 50% beamsplitter tsis muaj qhov xav tau txheej. Germanium tseem siv dav siv los ua cov txheej txheem qis rau kev tsim cov lim dej ntawm cov lim. Germanium npog tag nrho ntawm 8-14 micron cua sov thev naus laus zis thiab siv nyob rau hauv kab ke tshuab rau cov duab thaij duab thermal. Germanium tuaj yeem ua tau AR coated nrog Pob Zeb Diamond ua qhov ua qhov nyuaj rau sab pem hauv ntej optic.
    Germanium loj hlob siv cov txheej txheem Czochralski los ntawm cov tuam ntxhab me me hauv Belgium, Tebchaws USA, Tuam Tshoj thiab Lavxias. Qhov ntsuas tsis zoo ntawm Germanium hloov pauv sai nrog qhov kub thiab cov khoom ua opaque txhua nthwv dej siab me ntsis ntawm 350K raws li cov kis ntawm dej nyab nrog cov hluav taws xob thermal.
    Daim ntawv thov:
    • Zoo rau cov ntawv thov ze-IR
    • Broadband 3 txog 12 μm los tiv thaiv kev tha xim tiv thaiv
    • Zoo tagnrho rau cov ntawv thov uas yuav tsum muaj kev sib kis tsawg
    • Zoo rau qhov tsis muaj zog hluav taws xob CO2 laser kev siv
    Nta:
    • Cov germanium qhov rais tsis xa tawm ntawm 1.5µm thaj av lossis qis dua, yog li ntawd nws cov ntawv thov tseem ceeb yog nyob hauv thaj tsam IR.
    • Germanium qhov rai tuaj yeem siv rau hauv ntau qhov kev sim duab infrared.
