Calcium Fluoride (CaF2)
Bi-Convex Lenses

Ese ari maviri maface eBi-convex kana Double-convex (DCX) Spherical Lenzis ane denderedzwa uye ane yakafanana positive radii yekumisikidza, iwo ari positive lenzi ayo ari mukati makobvu pane kumucheto. Kana mwaranzi yakasanganiswa ichipfuura nepakati pawo, mwenje unochinjika kuenda panzvimbo yepakati. Bi-convex yakakurumbira kune akawanda ekupedzisira ekufungidzira maapplication mumamiriro ezvinhu apo chinhu nemufananidzo zviri kumativi akatarisana, zvakagadzirirwa kuve nefocal kureba f= (R1*R2)/((n-1)*(R2-R1) )).

Bi-convex lenzi (kana maviri-convex lenzi) anoita zvirinani kana chinhu chiri pedyo nelenzi uye reshiyo yeconjugate yakadzikira. Kana chinhu uye chinhambwe chemufananidzo zvakaenzana (1: 1 magnification), kwete chete spherical aberration inoderedzwa, asiwo kukanganisa, uye chromatic aberration inodzimwa nekuda kwekuenzanisa. Saka idzo sarudzo dzakanakisa kana chinhu nemufananidzo zviri paabsolute conjugate ratios padyo ne1: 1 ine diverging matanda ekuisa. Semutemo wezvigunwe, bi-convex lenses inoita zvakanaka mukati mekushomeka kwekukanganisa pane conjugate ratios pakati pe5: 1 ne1: 5, anoshandiswa kune relay imaging (Chaiyo Object uye Mufananidzo) maapplication. Kunze kwemhando iyi, ma plano-convex lenzi anowanzo kuve akakodzera.

Nekuda kwekutapurirana kwayo kwakakwira kubva ku0.18 µm kusvika ku8.0 μm, CaF2 inoratidza yakaderera refractive index inosiyana kubva ku1.35 kusvika 1.51 uye inowanzoshandiswa kune zvikumbiro zvinoda kutapurirana kwakanyanya mu infrared uye ultraviolet spectral ranges. Calcium fluoride zvakare yakanyatso makemikari inert uye inopa kuomarara kwepamusoro kana ichienzaniswa neyayo barium fluoride, uye magnesium fluoride makunakuna. Paralight Optics inopa Calcium Fluoride (CaF2) Bi-Convex Lenses inowanika nebroadband AR coating yakagadziridzwa ye2 µm kusvika 5 μm spectral renji yakaiswa panzvimbo dzese dziri mbiri. Uku kupfekedza kunoderedza zvakanyanya avhareji yekuratidzira kweiyo substrate isingasviki 1.25%, ichipa avhareji yekufambisa inopfuura 95% pamusoro peiyo AR coating renji. Tarisai maGrafu anotevera kune mareferensi ako.
