I-Calcium Fluoride (CaF2)
Amalensi e-Plano-Convex
Amalensi e-Plano-convex aletha ukuhlanekezela okuyisiyingi okuncane uma egxile kokungapheli (lapho into efanekiselwe ikude futhi isilinganiso se-conjugate siphezulu).Ngakho-ke zingamalensi okuya kuwo kumakhamera nezibonakude.Ukusebenza okuphezulu kufinyelelwa lapho indawo yeplano ibheke endizeni yokugxila efiselekayo, ngamanye amazwi, indawo egobile ibhekene nomugqa wesigameko obomvana.Amalensi e-Plano convex ayinketho enhle yokuhlanganisa ukukhanya noma ukugxila ezinhlelweni zisebenzisa ukukhanya okukodwa, ezimbonini ezifana nezimboni, ezemithi, amarobhothi, noma ezokuvikela.Ziyinketho yokonga yezicelo ezifunayo ngoba kulula ukuzenza.Njengomthetho wesithupha, amalensi e-plano-convex asebenza kahle uma into nesithombe kuku-absolute conjugate ratios > 5:1 noma < 1:5, ngakho ukuphambuka okuyindilinga, ikhoma nokuhlanekezela kuyehla.Uma ukukhuliswa okuphelele okufunayo kuphakathi kwalawa manani amabili, amalensi e-Bi-convex ngokuvamile afaneleka kakhulu.
Ngenxa yokudluliswa kwayo okuphezulu ukusuka ku-0.18 µm kuya ku-8.0 μm, i-CaF2ibonisa inkomba ephansi ye-refractive ehluka ukusuka ku-1.35 ukuya ku-1.51 futhi ijwayele ukusetshenziselwa izinhlelo zokusebenza ezidinga ukudluliswa okuphezulu kububanzi be-infrared ne-ultraviolet spectral.I-calcium fluoride nayo ayisebenzi ngamakhemikhali futhi inikeza ubulukhuni obuphakeme uma iqhathaniswa ne-barium fluoride yayo, kanye nabazala bayo be-magnesium fluoride.I-Paralight Optics inikeza i-Calcium Fluoride (CaF2) amalensi e-plano-convex anama-antireflection ebangeni elingu-1.65 µm ukuya ku-3.0 µm noma u-2 µm ukuya ku-5 µm ububanzi be-wavelength.Lokhu kunamathela kunciphisa kakhulu ukubukeka okumaphakathi kwe-substrate engaphansi kuka-1.25%, kuveza ukudluliswa kwesilinganiso esiphezulu okukhulu kuno-95% kulo lonke uhla lwe-AR lokunamathela.Hlola amagrafu alandelayo ukuze uthole izithenjwa zakho.
