Kalisiyumu Fluoride (CaF2)
Lens ya Bi-Concave

Indangantego ya Bi-concave cyangwa Double-concave (DCV) ninzira mbi zifite umubyimba mwinshi kuruhande kuruta hagati, iyo urumuri runyuze muri zo, ruratandukana kandi ingingo yibanze ni virtual.Lens ya Bi-Concave ifite radiyo ingana na curvature kumpande zombi za sisitemu ya optique, uburebure bwazo bwibanze ni bubi, kimwe na radiyo yo kugorora yubuso bugoramye.Uburebure butari bwiza butera urumuri rwibintu gutandukana, akenshi bikoreshwa mugutandukanya urumuri.Bitewe nimiterere yabyo, lens-bi-conave ikoreshwa muburyo bwo kwagura urumuri muburyo bwo kwagura urumuri rwo mu bwoko bwa Galilaya cyangwa kongera uburebure bwibanze bwibanze bwihuza ukoresheje bibiri muri sisitemu zisanzwe nka sisitemu yo kwerekana urumuri.Zifite kandi akamaro mugihe cyo kugabanya amashusho.Muri sisitemu ya optique, birasanzwe guhitamo optique yabo yitonze kugirango aberrasiyo yatangijwe nibyiza- nibibi-byibanda-uburebure bwa lens hafi yo guhagarika.Izi lens mbi zikoreshwa cyane muri telesikopi, kamera, lazeri cyangwa ibirahure kugirango bifashe sisitemu yo gukuza kurushaho.

Lens ya bi-konka (cyangwa lens-ebyiri) ni amahitamo meza mugihe ikintu nigishusho biri kumubare wuzuye wa conjugate (intera yikintu igabanijwe no gusuzugura amashusho) hafi ya 1: 1 hamwe no guhuza ibiti byinjira, nkuko bimeze kuri bi-convex lens.Bakoreshwa mugusubiramo amashusho (ikintu kiboneka nishusho) porogaramu.Iyo icyifuzo cyo gukuza cyuzuye kiri munsi ya 0.2 cyangwa kirenze 5, lens ya plano-conave mubisanzwe irakwiriye.

Bitewe nuko ikwirakwizwa cyane kuva 0.18 µm ikagera kuri 8.0 mm, fluoride ya Kalisiyumu yerekana indangagaciro yo hasi itandukana kuva kuri 1.35 kugeza 1.51 kandi ikoreshwa cyane mubisabwa bisaba kwanduza cyane murwego rwa infragre na ultraviolet, ifite indangagaciro ya 1.428 kuri 1.064 µm.CaF2 nayo inert ya chimique kandi itanga ubukana burenze ugereranije na fluoride ya barium, na babyara ba magnesium fluoride.Byinshi cyane byangiritse byangiritse bituma bigira akamaro ko gukoresha hamwe na lazeri.Paralight Optics itanga Kalisiyumu Fluoride (CaF2) Lens ya bi-conave ifite ibara rya antireflection kuri metero 3 kugeza kuri 5 µm.Iyi coating igabanya cyane impuzandengo yerekana substrate iri munsi ya 2.0%, itanga impuzandengo yo hejuru irenga 96% murwego rwose rwa AR.Reba Igishushanyo gikurikira kugirango ukore.
