Ua kūpono loa nā lens ZnSe no ka hoʻohana ʻana me nā laser CO2 mana kiʻekiʻe. Ma muli o ke kiʻekiʻe refractive index o ZnSe, hiki iā mākou ke hāʻawi i ka hoʻolālā spherical maikaʻi loa no ZnSe, ʻo ia ka hoʻolālā meniscus maikaʻi. Hoʻokumu kēia mau lens i nā aberrations liʻiliʻi, ka nui o nā kiko, a me nā hewa alo nalu e hoʻohālikelike ʻia me nā lens maikaʻi loa i hana ʻia e nā mea ʻē aʻe.
Hāʻawi ʻo Paralight Optics iā Zinc Selenide (ZnSe) Positive Meniscus Lenses i loaʻa me kahi uhi AR broadband i hoʻopaʻa ʻia no ka 8 µm 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.
