    Technical Parameters

    Lub Germanium raws li ib tug mono siv lead ua feem ntau siv nyob rau hauv semi-conductor yog tsis-absorptive ntawm 2μm mus rau 20μm IR cheeb tsam.Nws yog siv ntawm no ua ib qho khoom siv kho qhov muag rau IR cheeb tsam daim ntawv thov.
    Germanium yog cov khoom siv siab tshaj plaws uas yog siv los tsim cov prisms Attenuated Total Reflection (ATR) rau spectroscopy.Nws qhov refractive index yog xws li tias Germanium ua rau lub ntuj zoo 50% beamsplitter yam tsis tas yuav coatings.Germanium kuj tseem siv dav los ua lub substrate rau kev tsim cov lim dej kho qhov muag.Germanium npog tag nrho ntawm 8-14 micron thermal band thiab siv nyob rau hauv lub lens tshuab rau thermal imaging.Germanium tuaj yeem ua AR coated nrog pob zeb diamond ua rau lub ntsej muag tawv tawv heev.
    Germanium yog zus siv cov txheej txheem Czochralski los ntawm ib tug me me ntawm manufacturers nyob rau hauv Belgium, USA, Tuam Tshoj thiab Russia.Lub refractive index ntawm Germanium hloov sai heev nrog kub thiab cov khoom yuav opaque ntawm tag nrho cov wavelengths me ntsis saum toj no 350K raws li lub band sib txawv dej nyab nrog thermal electrons.
    Daim ntawv thov:
    • Zoo tagnrho rau cov ntawv thov nyob ze-IR
    • Broadband 3 mus rau 12 μm anti-reflection txheej
    • Zoo tagnrho rau daim ntawv thov uas yuav tsum tau dispersion tsawg
    • Zoo rau kev siv hluav taws xob qis CO2 laser
    Feature:
    • Cov qhov rais germanium no tsis kis ntawm thaj tsam 1.5µm lossis qis dua, yog li nws daim ntawv thov tseem ceeb yog nyob rau thaj tsam IR.
    • Germanium windows tuaj yeem siv rau hauv ntau yam kev sim infrared.
