Calcium Fluoride (CaF2)
Magalasi a Plano-Convex
Magalasi a plano-convex amapereka kupotoza kocheperako poyang'ana mopanda malire (pamene chinthu chojambulidwa chili patali ndipo chiŵerengero cha conjugate ndichokwera). Chifukwa chake ndi ma lens opita ku makamera ndi ma telescopes. Kuchita bwino kwambiri kumachitika pamene plano pamwamba ikuyang'anizana ndi ndege yomwe ikufunidwa, mwa kuyankhula kwina, malo opindika amayang'ana pamtengo wopindika. Magalasi a Plano convex ndi chisankho chabwino pakuwombana kopepuka kapena kuyang'ana kwambiri pakugwiritsa ntchito kuwunikira kwa monochromatic, m'mafakitale monga mafakitale, mankhwala, robotics, kapena chitetezo. Iwo ndi chisankho chandalama pazovuta zofunsira chifukwa ndizosavuta kupanga. Monga lamulo la chala chachikulu, magalasi a plano-convex amachita bwino pamene chinthucho ndi chithunzicho zili mtheradi conjugate ratios> 5: 1 kapena <1: 5, kotero spherical aberration, coma ndi kupotoza zimachepetsedwa. Pamene kukulitsa kofunikira kuli pakati pa zikhalidwe ziwirizi, magalasi a Bi-convex nthawi zambiri amakhala oyenera.
Chifukwa cha kufalikira kwakukulu kuchokera ku 0.18 μm mpaka 8.0 μm, CaF2imawonetsa index yotsika yotsika kuchokera ku 1.35 mpaka 1.51 ndipo imagwiritsidwa ntchito kwambiri pamapulogalamu omwe amafunikira kufalikira kwakukulu mumitundu ya infrared ndi ultraviolet spectral. Calcium fluoride ndiyomwe imalowa m'thupi ndipo imapereka kuuma kopambana poyerekeza ndi barium fluoride, ndi azisuwani ake a magnesium fluoride. Paralight Optics imapereka Calcium Fluoride (CaF2) magalasi a plano-convex okhala ndi zokutira zotchingira mafunde amtundu wa 1.65 µm mpaka 3.0 µm kapena 2 µm mpaka 5 µm kutalika kwa mafunde. Kupaka uku kumachepetsa kwambiri mawonekedwe a gawo lapansi lochepera 1.25%, kutulutsa kufalikira kwapakati kuposa 95% pamitundu yonse ya zokutira za AR. Yang'anani m'ma Grafu otsatirawa kuti mupeze zolozera zanu.
