Zinc Selenide (ZnSe)
Ibyiza bya Meniscus

Lens ya Meniscus ikoreshwa cyane cyane mukwibanda kubito bito cyangwa gukusanya porogaramu.Zitanga imikorere isumba izindi kugabanya cyane aberrasi.Ibyiza bya menisque (convex-concave), bigizwe nubuso bwa convex hamwe nubuso bunini kandi bukabyimbye hagati kuruta ku mpande & bitera imirasire yumucyo guhurira, byashizweho kugirango hagabanuke aberrasi muri sisitemu ya optique.Iyo bikoreshejwe kugirango ushireho urumuri rwegeranye, uruhande rwa convex rugomba guhura ninkomoko kugirango hagabanuke aberration.Iyo ikoreshejwe ifatanije nizindi lens, lens nziza ya meniscus izagabanya uburebure bwibanze kandi yongere umubare wumubare (NA) wa sisitemu utabanje kwinjiza aberrasi.Kubera ko lens nziza ya menisque ifite radiyo nini yo kugabanuka kuruhande rwuruzitiro kuruta kuruhande rwa convex, amashusho nyayo arashobora gushirwaho.

Lnse ZnSe irakwiriye cyane cyane gukoreshwa hamwe na lazeri nyinshi za CO2.Bitewe nubushakashatsi buhanitse bwa ZnSe, turashobora gutanga igishushanyo mbonera cyiza cya ZnSe, nigishushanyo cyiza cya menisk.Izi lens zitera aberrasi ntoya, ingano yikibanza, hamwe namakosa yumurongo ugereranije nibisobanuro byiza byahimbwe nibindi bikoresho.

Paralight Optics itanga Zinc Selenide (ZnSe) Lens nziza ya Meniscus Lens iboneka hamwe numuyoboro mugari wa AR washyizwe hejuru ya 8 µm kugeza 12 mkm ya spécranité yashyizwe kumurongo yombi.Iyi coating igabanya cyane hejuru yubuso bwo hejuru bwa substrate, itanga impuzandengo yikwirakwizwa rirenga 97% murwego rwose rwa AR.
