    Cov Kev Kawm Siv Tau

    Calcium Fluoride muaj ntau qhov IR thov li spectroscopic CaF2 qhov rai, CaF2 prisms thiab CaF2 lo ntsiab muag. Tshwj xeeb tshaj yog qib ntshiab ntawm Calcium Fluoride (CaF2) pom cov ntawv thov muaj txiaj ntsig ntawm UV thiab raws li UV Excimer laser qhov rai. Calcium Fluoride (CaF2) muaj doped nrog Europium ua cov gamma-ray scintillator thiab tawv dua Barium Fluoride.
    Calcium Fluoride tuaj yeem siv rau ntau daim ntawv thov, suav nrog lub tshuab nqus tsev ultra violet, ultra violet thiab duab hluav taws xob thermal duab. Calcium fluoride yog ib txwm siv nyob rau hauv kev tsim qauv apochromatic los txo cov teeb meem sib kis hauv qhov muag, ob qho tib si hauv koob yees duab thiab tsom iav, thiab tau siv hauv kev lag luam roj thiab roj ua cov khoom lag luam hauv cov khoom kuaj thiab tsom iav. Feem ntau siv nyob rau hauv lub qhov rais spectroscopic, zoo li hauv kev ntsuas cua sov thiab lwm qhov chaw sib txawv qhov siab kis tau ntawm 0.2µm thiab 8µm yuav tsum tau, calcium fluoride raug tawm tsam los ntawm ob peb reagents thiab muaj qhov tsis tshua muaj nqus coefficient thiab siab tsis zoo qhov cuam tshuam, muaj txiaj ntsig zoo hauv nws siv hauv excimer laser tshuab.
    Calcium Fluoride yog siv nyob rau hauv cov tshuab tsom rau cov nplais teeb thiab focussing. CaF2 lo ntsiab muag thiab lub qhov rais pub tshaj 90% kev xa los ntawm 350nm txog rau 7µm thiab yog siv hauv cov tshuab hluav taws xob qhov twg yuav tsum tau muaj ntau qhov yoj yoj. Calcium Fluoride qhov ntsuas qis ntawm kev tso tawm cia ua rau Calcium Fluoride siv nyob rau hauv cov kab ke tsis siv tshuaj tiv thaiv kev tsis haum, tsis zoo li lwm cov ntaub ntawv IR.
