    Technical Parameter

    Calcium Fluoride yakapararira IR kunyorera seyakacherekedza CaF2 windows, CaF2 prism uye CaF2 lenses. Kunyanya akachena mamaki eCalcium Fluoride (CaF2) anowana anoshanda kunyorera muUV uye seUV Excimer laser windows. Calcium Fluoride (CaF2) inowanikwa doped neEuropium segamma-ray scintillator uye yakaoma kupfuura Barium Fluoride.
    Calcium Fluoride inogona kushandiswa kune akawanda mashandisirwo, anosanganisira vharuvhu ultra violet, ultra violet uye infrared thermal imaging. Calcium fluoride inowanzo shandiswa muapochromatic dhizaini yekudzikisa mwenje kupenya mumalensi, ese ari mumakamera uye teresikopu, uye anoshandisa mumafuta uye gasi indasitiri sechinhu mune ma detectors uye maspremeter. Inonyanya kushandiswa mumawindo anotaridzika, pamwe nekufungidzira kwekushisa uye mamwe masisitimu uko kutapurirana kukuru pakati pe 0.2µm ne 8µm kunodiwa, calcium fluoride inorwiswa nema reagents mashoma uye inopa yakaderera yekumwiwa coefficient uye yakanyanya kukuvara chikumbaridzo, inobatsira mukushandisa kwayo mune excimer Laser hurongwa.
    Calcium Fluoride inoshandiswa mumasystemsycopy masisitimu ekutungamira kwedanda uye kutarisisa. Iwo maCaF2 lenses nemahwindo anopa anopfuura makumi mapfumbamwe muzana kutapurirana kubva pa350nm kusvika pa7µm uye anoshandiswa mumasystem ekuratidzira uko panodiwa nzvimbo yakatambanuka yehurefu. Calcium Fluoride yakaderera indekisi yekuburitsa inobvumidza Calcium Fluoride kushandiswa mumasisitimu pasina kushandisa antireflection coatings, kusiyana nezvimwe IR zvigadzirwa.
