I-Zinc Selenide (ZnSe)
I-Bi-Convex Lens

I-Bi-Convex noma i-Double-Convex (DCX) Amalensi ayindilinga ayindilinga futhi ane-curvature efanayo kuzo zombili izinhlangothi zelensi, ngakho ayasimetric futhi anobude bokugxila obuphozizithivu. Ekuhlanganiseni kweyunithi, ikhoma nokuhlanekezela kuyacisha ngenxa yokulinganisa. Lawa ma-lens angasetshenziswa ukugxila ekukhanyeni okungenayo futhi adumile ezinhlelweni eziningi zezithombe ezinomkhawulo.

Yize amalensi e-Bi-convex enciphisa ukuphamba ezimeni lapho amabanga ento nesithombe elingana noma acishe alingane, lapho enquma phakathi kwelensi ye-bi-convex noma ye-DCX kanye nelensi ye-plano-convex, womabili abangela ukuhlangana kwesigameko esikhanyayo, ngokuvamile kungcono ukukhetha ilensi ye-bi-convex yokunciphisa ukujika uma isilinganiso sento nesithombe samabanga (isilinganiso esiphelele se-conjugate) siphakathi kuka-5:1 no-1:5. Ngaphandle kwalolu hlu, amalensi e-plano-convex ngokuvamile ayathandwa.

Amalensi e-ZnSe afaneleka kahle kakhulu ukusetshenziswa namalaser anamandla e-CO2. I-Paralight Optics inikezela ngamalensi e-Zinc Selenide (ZnSe) Bi-Convex atholakala nge-broadband AR coating elungiselelwe ububanzi obungama-8 kuya ku-12 μm obufakwe kuzo zombili izindawo. Lokhu kunamathela kunciphisa kakhulu ukubukeka okuphezulu kwendawo engaphansi, kunikeze ukudluliswa okumaphakathi okungaphezu kuka-97% kulo lonke uhla lwe-AR.
