Kalisiyumu Fluoride (CaF)₂)
Lens ya Bi-Convex

Ubuso bwombi bwa Bi-convex cyangwa Double-convex (DCX) Lens Spherical Lens ni spherical kandi ifite radiyo nziza imwe ya curvature, ni lens nziza nziza zifite umubyimba hagati kuruta kuruhande. Iyo imirasire yegeranijwe inyuze muri yo, urumuri ruhinduka kumurongo wibanze. Bi-convex irazwi cyane kubikorwa byinshi byerekana amashusho mugihe ibintu hamwe nishusho biri kumpande zinyuranye, byashizweho kugirango uburebure bwa f = (R1 * R2) / ((n-1) * (R2-R1 )).

Icyitegererezo OEM irasaba

Lens ya bi-convex (cyangwa lens ebyiri-convex) ikora neza mugihe ikintu cyegereye lens kandi igipimo cya conjugate kiri hasi. Iyo ikintu nintera yintera bingana (1: 1 gukuza), ntabwo aberration ya serefegitura yagabanutse gusa, ahubwo no kugoreka, kandi aberrasi ya chromatic ihagarikwa kubera guhuza. Nibwo buryo bwiza bwo guhitamo mugihe ikintu nishusho biri kumurongo wuzuye wa conjugate hafi ya 1: 1 hamwe no gutandukanya ibiti. Nkuko bisanzwe bigenda, lens ya bi-convex ikora neza mugihe cyo gukuramo byibuze kuri conjugate ratios hagati ya 5: 1 na 1: 5, zikoreshwa fo relay amashusho (Real Object and Image). Hanze y'uru rutonde, lens ya plano-convex mubisanzwe irakwiriye.

Bitewe nuko ikwirakwizwa cyane kuva 0.18 µm kugeza kuri 8.0 mm, CaF2 yerekana indangagaciro yo hasi itandukana kuva kuri 1.35 kugeza 1.51 kandi ikoreshwa mubisabwa bisaba kwanduza cyane murwego rwa infragre na ultraviolet. Kalisiyumu fluoride nayo yinjizwamo imiti kandi itanga ubukana burenze ugereranije na fluoride ya barium, hamwe na mubyara wa magnesium fluoride. Paralight Optics itanga Kalisiyumu Fluoride (CaF2) Bi-Convex Lens iboneka hamwe numuyoboro mugari wa AR utwikiriye neza kuri 2 µm kugeza kuri 5 mμm ya spécranre yashyizwe kumpande zombi. Iyi coating igabanya cyane impuzandengo yerekana substrate iri munsi ya 1.25%, itanga impuzandengo yikwirakwizwa irenga 95% murwego rwose rwa AR. Reba Igishushanyo gikurikira kugirango ukore.
