Calcium Fluoride (CaF2)
Magalasi a Bi-Concave

Ma lens a Bi-concave kapena Double-concave (DCV) ndi ma lens oyipa omwe amakhala okulirapo m'mphepete kuposa apakati, kuwala kumadutsa pakati pawo, kumasiyana ndipo komwe kumawonekera.Magalasi a Bi-Concave ali ndi utali wofanana wopindika mbali zonse za mawonekedwe owoneka bwino, kutalika kwawo ndi koyipa, komanso ma radii a kupindika kwa malo opindika.Kutalikirana kolakwika kumapangitsa kuti kuwala kwa zochitika kuphatikizidwe, nthawi zambiri amagwiritsidwa ntchito kupatutsa mtengo wozungulira.Chifukwa cha mawonekedwe awo, ma lens a bi-concave amagwiritsidwa ntchito kukulitsa kuwala muzowonjezera zowunikira zamtundu wa ku Galileya kapena kukulitsa utali wokhazikika wa ma lens otembenuza pogwiritsa ntchito awiriawiri pamakina omwe alipo monga makina owonera kuwala.Zimakhalanso zothandiza pankhani yochepetsera zithunzi.M'mawonekedwe a Optical system, ndizofala kusankha ma optics awo mosamala kuti zosokoneza zomwe zimayambitsidwa ndi ma lens owoneka bwino komanso olakwika atalikirapo pafupifupi kuletsa.Magalasi oyipawa amagwiritsidwa ntchito kwambiri mu telescopes, makamera, ma lasers kapena magalasi kuti athandizire makina okulitsa kukhala ophatikizika.

Ma lens a Bi-concave (kapena ma lens awiri-concave) ndiye chisankho chabwino kwambiri ngati chinthu ndi chithunzi zili pamlingo wa conjugate (mtunda wa chinthu wogawanika ndi disdance) pafupi ndi 1: 1 yokhala ndi matabwa olowera, monga momwe zimakhalira ndi bi-convex. magalasi.Amagwiritsidwa ntchito poyesereranso kujambula (chinthu chenicheni ndi zithunzi).Ngati kukulitsa kofunikirako kuli kochepera 0.2 kapena kupitilira 5, magalasi a plano-concave nthawi zambiri amakhala oyenera.

Chifukwa cha kufalikira kwakukulu kuchokera ku 0.18 µm mpaka 8.0 μm, Calcium fluoride imawonetsa 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, ili ndi index yowonekera ya 1.428 pa 1.428 µm.CaF2 imakhalanso yopanda mankhwala ndipo imapereka kuuma kopambana poyerekeza ndi barium fluoride, ndi magnesium fluoride cousins.Kuwonongeka kwake kwakukulu kwa laser kumapangitsa kuti ikhale yothandiza kugwiritsidwa ntchito ndi ma lasers a excimer.Paralight Optics imapereka magalasi a Calcium Fluoride (CaF2) Bi-concave okhala ndi zokutira zotchingira mafunde amtundu wa 3 mpaka 5 µm wavelength.Kupaka uku kumachepetsa kwambiri mawonekedwe a gawo lapansi lochepera 2.0%, kutulutsa kufalikira kwapakati kuposa 96% pamitundu yonse ya zokutira za AR.Yang'anani m'ma Grafu otsatirawa kuti mupeze zolozera zanu.
