CaF2 Windows
Calcium Fluoride ili ndi ntchito yofalikira ya IR monga mawindo a CaF2 owoneka bwino, ma prism a CaF2 ndi ma lens a CaF2.Makamaka magiredi abwino a Calcium Fluoride (CaF2) amapeza ntchito yothandiza mu UV komanso mawindo a UV Excimer laser.Calcium Fluoride (CaF2) imapezeka yopangidwa ndi Europium ngati gamma-ray scintillator ndipo ndi yolimba kuposa Barium Fluoride.
Calcium Fluoride itha kugwiritsidwa ntchito pazinthu zambiri, kuphatikiza vacuum ultra violet, ultra violet ndi infrared thermal imaging.Calcium fluoride nthawi zambiri amagwiritsidwa ntchito popanga apochromatic kuti achepetse kuwala kwa magalasi, makamera ndi ma telescopes, ndipo amagwiritsidwa ntchito mumakampani amafuta ndi gasi ngati gawo lazowunikira ndi ma spectrometer.Amagwiritsidwa ntchito makamaka m'mawindo a spectroscopic, komanso pazithunzi zotentha ndi machitidwe ena kumene kufalikira kwakukulu pakati pa 0.2µm ndi 8µm kumafunika, calcium fluoride imawukiridwa ndi ma reagents ochepa ndipo imapereka coefficient yochepetsetsa komanso kuwonongeka kwakukulu, kopindulitsa pogwiritsira ntchito excimer. machitidwe a laser.
Calcium Fluoride imagwiritsidwa ntchito m'makina owonera ma spectroscopy pakuwongolera ndi kuyang'ana.Ma lens ndi mazenera a CaF2 amapereka kupitilira 90% kuchokera ku 350nm kupita ku 7µm ndipo amagwiritsidwa ntchito m'makina a spectrometer komwe kumafunika kutalika kwa mafunde.Calcium Fluoride yotsika index of refraction imalola Calcium Fluoride kugwiritsidwa ntchito m'makina osagwiritsa ntchito zokutira zotchingira, mosiyana ndi zida zina za IR.
