Zinc Selenide (ZnSe)
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).

Lnse ZnSe irakwiriye cyane cyane gukoreshwa hamwe na lazeri nyinshi za CO cyangwa CO2.Mubyongeyeho, barashobora gutanga ihererekanyabubasha rihagije mukarere kagaragara kugirango bemererwe gukoresha urumuri rugaragara, nubwo ibitekerezo byinyuma bishobora kugaragara cyane.Paralight Optics itanga Zinc Selenide (ZnSe) Plano-Concave (PCV) Lens iboneka hamwe numuyoboro mugari wa AR wagizwe neza na 2 µm - 13 μ m cyangwa 4.5 - 7.5 μ m cyangwa 8 - 12 μ m urwego rwerekanwa rwashyizwe hejuru yimiterere yombi.Iyi coating igabanya cyane hejuru yubuso bwa substrate, itanga impuzandengo yikigereranyo kirenga 92% cyangwa 97% murwego rwose rwa AR.Reba ibishushanyo byerekana.
