Kalisiyumu Fluoride (CaF2)
Lens

Indangantego ya plano-incike ninzira mbi zifite umubyimba mwinshi kurenza hagati, iyo urumuri runyuze muri zo, ruratandukana kandi ingingo yibanze ni virtual.Uburebure bwabo bwibanze ni bubi, kimwe na radiyo yo kugabanuka yubuso bugoramye.Bitewe nuburyo bubi bwa spherical aberration, lens ya plano-conave irashobora gukoreshwa kugirango iringanize aberifike iterwa nizindi lens muri sisitemu optique.Lens ya plano-conave ifite akamaro ko gutandukanya urumuri rwegeranijwe no gukusanya urumuri ruhuza, bikoreshwa mu kwagura urumuri no kongera uburebure bwibanze muri sisitemu ya optique ihari.Izi lens mbi zikoreshwa cyane muri telesikopi, kamera, lazeri cyangwa ibirahure kugirango bifashe sisitemu yo gukuza kurushaho.

Lens ya plano-conve ikora neza mugihe ikintu nigishusho biri kumubare wuzuye wa conjugate, birenze 5: 1 cyangwa munsi ya 1: 5.Kuri iki kibazo, birashoboka kugabanya aberrasique, koma, no kugoreka.Kimwe na lens ya plano-convex, kugirango ugere ku bushobozi ntarengwa Ubuso bugoramye bugomba guhura nintera nini nini cyangwa conjugate itagira umupaka kugirango ugabanye aberrasi (usibye iyo ikoreshejwe na lazeri zifite ingufu nyinshi aho ibi bigomba guhindurwa kugirango bikureho bishoboka. kwibanda).

Bitewe nuko ikwirakwizwa cyane kuva 0.18 µm ikagera kuri 8.0 μ mm, CaF2 yerekana indangagaciro ntoya itandukana kuva kuri 1.35 kugeza 1.51 kandi ikoreshwa mubisabwa bisaba kwanduza cyane murwego rwa infragre na ultraviolet, ifite indangagaciro ya 1.428 kuri 1.064 µm .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) plano-concave lens hamwe na antireflection ya coire ya 2 µm kugeza 5 µm yumurambararo wabitswe hejuru yimiterere yombi.Iyi coating igabanya cyane ubuso bugaragara bwa substrate, itanga impuzandengo yikwirakwizwa rirenga 97% murwego rwose rwa AR.Reba Igishushanyo gikurikira kugirango ukore.

Ibikoresho:

Kalisiyumu Fluoride (CaF2)

Amahitamo yo gutwikira:

Bidatwikiriwe cyangwa hamwe na Antireflection Coatings

Uburebure bwibanze:

Kuboneka kuva -18 kugeza kuri mm 50

Porogaramu:

Bikwiriye gukoreshwa muri Excimer Laser Porogaramu, muri Spectroscopy hamwe na Cooled Thermal Imaging
