    Technical Parameters

    Calcium Fluoride muaj ntau daim ntawv thov IR raws li spectroscopic CaF2 qhov rais, CaF2 prisms thiab CaF2 lo ntsiab muag.Tshwj xeeb tshaj yog cov qib ntshiab ntawm Calcium Fluoride (CaF2) pom cov ntawv thov tseem ceeb hauv UV thiab raws li UV Excimer laser windows.Calcium Fluoride (CaF2) muaj doped nrog Europium ua gamma-ray scintillator thiab nyuaj dua li Barium Fluoride.
    Calcium Fluoride tuaj yeem siv rau ntau daim ntawv thov, suav nrog lub tshuab nqus tsev ultraviolet, ultra violet thiab infrared thermal imaging.Calcium fluoride yog ib txwm siv nyob rau hauv apochromatic tsim los txo lub teeb dispersion nyob rau hauv lo ntsiab muag, ob qho tib si nyob rau hauv lub koob yees duab thiab telescopes, thiab tau siv nyob rau hauv cov roj thiab roj kev lag luam raws li ib feem nyob rau hauv detectors thiab spectrometers.Feem ntau siv nyob rau hauv spectroscopic windows, nrog rau hauv thermal imaging thiab lwm yam systems uas yuav tsum tau high kis tau tus mob ntawm 0.2µm thiab 8µm, calcium fluoride yog tawm tsam los ntawm ob peb reagents thiab muaj ib tug tsawg absorption coefficient thiab siab puas tsuaj pib, muaj txiaj ntsim nyob rau hauv nws siv nyob rau hauv excimer. laser systems.
    Calcium Fluoride yog siv nyob rau hauv spectroscopy systems rau beam steering thiab focussing.Lub CaF2 lo ntsiab muag thiab qhov rais muaj tshaj 90% kis tau tus mob los ntawm 350nm mus txog rau 7µm thiab yog siv nyob rau hauv spectrometer systems uas yuav tsum tau ib tug dav wavelength ntau yam.Calcium Fluoride qhov qis qis ntawm kev cuam tshuam tso cai rau Calcium Fluoride siv rau hauv cov tshuab yam tsis muaj kev siv cov tshuaj tiv thaiv kev cuam tshuam, tsis zoo li lwm cov ntaub ntawv IR.
