Magalasi a plano-concave amachita bwino ngati chinthu ndi chithunzicho zili pamiyezo yolumikizana, yoposa 5:1 kapena kuchepera 1:5. Pachifukwa ichi, ndizotheka kuchepetsa kuphulika kwa spherical, coma, ndi kupotoza. Mofananamo ndi magalasi a plano-convex, kuti akwaniritse bwino kwambiri malo opindika ayenera kuyang'anizana ndi mtunda waukulu kwambiri wa chinthu kapena cholumikizira chopanda malire kuti achepetse kufalikira kwa spherical (kupatula ngati atagwiritsidwa ntchito ndi ma laser amphamvu kwambiri pomwe izi ziyenera kusinthidwa kuti zithetse kuthekera kwa pafupifupi. kuganizira).
Chifukwa cha kufalikira kwake kwakukulu kuchokera ku 0.18 µm mpaka 8.0 μm, CaF2 imawonetsa index yotsika yotsika yosiyana kuchokera ku 1.35 mpaka 1.51 ndipo imagwiritsidwa ntchito kwambiri pamapulogalamu omwe amafunikira kufalikira kwakukulu mumitundu ya infrared ndi ultraviolet spectral, ili ndi index yowonekera ya 1.4024 pa 1.4028 pa 1. . Calcium fluoride ndiyomwe imalowa m'thupi ndipo imapereka kuuma kopambana poyerekeza ndi barium fluoride, ndi azisuwani ake a magnesium fluoride. Paralight Optics imapereka magalasi a Calcium Fluoride (CaF2) a plano-concave okhala ndi zokutira zotchingira mawonedwe a kutalika kwa 2 µm mpaka 5 µm zoyikidwa pamalo onse awiri. Kupaka uku kumachepetsa kwambiri kuwunikira kwa gawo lapansi, kumabweretsa kufalikira kwapakati pa 97% pamitundu yonse ya zokutira za AR. Yang'anani m'ma Grafu otsatirawa kuti mupeze zolozera zanu.
Calcium Fluoride (CaF2)
Zovala zosaphimbidwa kapena zokhala ndi Antireflection Coatings
Amapezeka kuchokera -18 mpaka -50 mm
Zoyenera Kugwiritsidwa Ntchito mu Excimer Laser Applications, mu Spectroscopy ndi Cooled Thermal Imaging
