Calcium Fluoride (CaF2)
Calcium Fluoride (CaF2) yog ib lub cubic siv lead ua, nws yog mechanically thiab ib puag ncig ruaj khov.CaF2Feem ntau yog siv rau cov ntawv thov uas yuav tsum tau muaj kev sib kis tau zoo nyob rau hauv infrared thiab ultraviolet spectral ranges.Cov ntaub ntawv nthuav tawm qhov ntsuas qis qis, sib txawv ntawm 1.35 txog 1.51 hauv nws qhov kev siv ntau ntawm 180 nm txog 8.0 μm, nws muaj qhov ntsuas qhov ntsuas ntawm 1.428 ntawm 1.064 µm.Calcium fluoride kuj tseem muaj tshuaj lom neeg tsis zoo thiab muaj qhov nyuaj dua piv rau nws cov barium fluoride, magnesium fluoride, thiab lithium fluoride kwv tij.Txawm li cas los xij, CaF2yog me ntsis hygroscopic thiab susceptible rau thermal shock.Calcium Fluoride yog qhov zoo tagnrho rau txhua daim ntawv thov uas nws qhov kev puas tsuaj loj, tsis muaj fluorescence, thiab siab homogeneity muaj txiaj ntsig.Nws qhov kev puas tsuaj loj heev ua rau nws siv hauv excimer laser daim ntawv thov, nws nquag siv hauv spectroscopy thiab txias thermal imaging.

Tswv yim: Crystal rau infrared siv feem ntau zus siv ib txwm mined fluorite los txo nqi.Rau UV thiab VUV daim ntaub ntawv chemically npaj raw khoom yog feem ntau siv.Rau Excimer laser daim ntawv thov, peb tsuas yog siv cov qib siab tshaj plaws ntawm cov khoom tshwj xeeb uas tau xaiv thiab siv lead ua.
Yog xav paub ntxiv cov ntaub ntawv tshwj xeeb hauv qhov tob, thov saib peb cov catalog optics kom pom peb cov kev xaiv ua tiav ntawm optics ua los ntawm Calcium Fluoride.
