ʻOiai ʻo nā lens Bi-convex e hōʻemi i nā aberrations i nā kūlana i like a ʻaneʻane like paha ka mamao o ka mea a me ke kiʻi, i ka wā e hoʻoholo ai ma waena o kahi lens bi-convex a i ʻole DCX a me kahi lens plano-convex, ʻo ia mau mea ʻelua e hoʻohuli ai i ka mālamalama hanana collimated, ʻo ia. ʻoi aku ka maikaʻi o ke koho ʻana i kahi lens bi-convex no ka hōʻemi ʻana i nā aberrations inā ʻo ka ratio o ka mea a me nā kiʻi mamao (ka ratio conjugate piha) ma waena o 5:1 a me 1:5. Ma waho aʻe o kēia laulā, makemake ʻia nā lens plano-convex.
Ua kūpono loa nā lens ZnSe no ka hoʻohana ʻana me nā laser CO2 mana kiʻekiʻe. Hāʻawi ʻo Paralight Optics iā Zinc Selenide (ZnSe) Bi-Convex Lenses i loaʻa me kahi uhi AR broadband i hoʻopaʻa ʻia no ka 8 a 12 μm spectral range i waiho ʻia ma nā ʻaoʻao ʻelua. Hoʻemi nui kēia uhi ʻana i ka noʻonoʻo ʻana o ka ʻili kiʻekiʻe o ka substrate, e hāʻawi ana i ka hoʻoili awelika ma mua o 97% ma luna o ka laulā uhi AR āpau. E nānā i nā kiʻi ma lalo no kāu mau kuhikuhi.
