Calcium Fluoride (CaF2)
Lilense tsa Plano-Convex
Lilense tsa Plano-convex li fana ka ho khopama ho fokolang ha li tsepamisitse maikutlo ho sa feleng (ha ntho e tšoantšetsoang e le hole 'me karolelano ea conjugate e phahame). Ka hona, ke lilense tse eang ho likhamera le libonela-hōle. Bokhabane bo phahameng bo fihlelleha ha bokaholimo ba plano bo shebane le sefofane se lakatsehang, ka mantsoe a mang, bokaholimo bo kobehileng bo shebane le leballo la liketsahalo tse hohlaneng. Lilense tsa Plano convex ke khetho e ntle bakeng sa ho kopana ha leseli kapa ho tsepamisa maikutlo lits'ebetsong tse sebelisang khanya ea monochromatic, liindastering tse kang indasteri, meriana, robotics, kapa ts'ireletso. Ke khetho ea moruo bakeng sa likopo tse hlokang hobane li bonolo ho li etsa. E le molao oa monoana, lilense tsa plano-convex li sebetsa hantle ha ntho le setšoantšo li le ka ho feletseng conjugate ratios> 5: 1 kapa <1: 5, kahoo spherical aberration, koma le ho sotha li fokotsehile. Ha kholo e lakatsehang e le lipakeng tsa litekanyetso tsena tse peli, lilense tsa Bi-convex hangata li loketse haholoanyane.
Ka lebaka la phetiso ea eona e phahameng ho tloha ho 0.18 µm ho isa ho 8.0 μm, CaF2e bonts'a index e tlase ea refractive e fapaneng ho tloha ho 1.35 ho isa ho 1.51 mme e sebelisoa hangata bakeng sa lits'ebetso tse hlokang phetisetso e phahameng ka har'a marang-rang a infrared le ultraviolet spectral. Calcium fluoride le eona ha e sebetse hantle ka lik'hemik'hale 'me e fana ka boima bo phahameng ha bo bapisoa le barium fluoride ea eona, le magnesium fluoride motsoala. Paralight Optics e fana ka Calcium Fluoride (CaF2) lilense tsa plano-convex tse nang le lirafshoa tse thibelang khanya bakeng sa sebaka sa 1.65 µm ho isa ho 3.0 µm kapa 2 µm ho isa ho 5 µm leqhubu la bolelele. Ho roala hona ho fokotsa haholo ponahatso e tloaelehileng ea karoloana e ka tlase ho 1.25%, 'me e fana ka phetisetso e kholo ho feta 95% ho pholletsa le mefuta eohle ea likhoele tsa AR.
