I-Calcium Fluoride (CaF2)
Amalensi e-Plano-Convex

Amalensi e-Plano-convex (PCX) angamalensi aqondile ajiyile phakathi nendawo kunasemaphethelweni, lapho imisebe ehlanganisiwe idlula kuwo, ukukhanya kuguqukela endaweni okugxilwe kuyo ngokomzimba. Amalensi e-Plano-convex anohlangothi olulodwa oluyisicaba kanye nohlangothi olulodwa olugobile olunomngcele oqondile wokugoba. Amalensi e-Plano-Convex anobude bokugxila obuhle futhi asondela ngendlela engcono kakhulu yezinhlelo zokusebenza ze-conjugate ezingapheli nezinomkhawulo. Lawa ma-lens agxilisa i-collimated beam ekugxilweni kwangemuva futhi ahambisane nokukhanya okuvela kumthombo wephoyinti. Aklanywe ngendlela enokuphenduka okuncane okuyindilinga futhi anobude bokugxila obunikezwe ngu:
f= R/(n-1),
lapho u-R eyirediyasi yokugoba yengxenye ye-convex yelensi futhi n eyinkomba yokuphikisa.

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 zilula 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 be-magnesium fluoride. IParalight Optics inikeza iCalcium 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.
