Zinc Selenide
I-Meniscus Lens Engalungile

Amalensi e-meniscus asetshenziswa ngokuyinhloko ukugxila kumasayizi amabala amancane noma izinhlelo zokusebenza zokuhlanganisa. Bahlinzeka ngokusebenza okuphezulu kakhulu ngokunciphisa kakhulu ukuphambuka okuyindilinga. Amalensi e-meniscus (i-convex-concave) engemihle , ahlanganisa indawo eyi-convex nendawo eqondile futhi azacile maphakathi kunasemaphethelweni futhi abangele ukuthi imisebe yokukhanya ihlukane, aklanyelwe ukunciphisa ukujika okuyindilinga kumasistimu okubona.

Uma isetshenziselwa ukuphambukisa ukukhanya ezinhlelweni ezinwetshwayo ze-beam, indawo ekhombekile kufanele ibhekane ne-beam ukuze kuncishiswe ukuphuma okuyindilinga. Uma isetshenziswa ihlanganiswe nenye ilensi, ilensi ye-meniscus engeyinhle izokhuphula ubude bendawo futhi yehlise indawo yokuvula izinombolo (NA) yesistimu.

Amalensi e-ZnSe alungele ukusetshenziswa kwe-CO2 lasers ngenxa yezici ezinhle kakhulu zokucabanga kanye nokumelana okuphezulu nokushaqeka okushisayo. I-Paralight Optics inikeza amalensi e-meniscus e-Zinc Selenide (ZnSe) anegethivu, lawa ma-lens ehlisa i-NA yesistimu yokubona futhi atholakala nge-broadband anti-reflection coating, ethuthukiselwe ububanzi obuyi-8 µm kuya ku-12 μm obufakwe kuzo zombili izindawo kanye nemikhiqizo. ukudluliswa okumaphakathi okungaphezu kuka-97% kulo lonke uhla lokumboza lwe-AR.
