Ahakoa ka whakaitihia e nga arotahi Bi-convex nga rereke i nga ahuatanga e rite ana, e tata ana ranei te tawhiti o te ahanoa me te atahanga, i te wa e whakatau ana i waenga i te arotahi rua-convex, DCX ranei me te arotahi plano-convex, na enei mea e rua ka huri te marama mai i te whakakotahitanga, he Ko te tikanga he pai ake ki te whiriwhiri i te arotahi bi-convex hei whakaiti i nga rereke mena ko te ōwehenga o te ahanoa me te tawhiti o te atahanga (te ōwehenga whakakotahi tino) kei waenga i te 5:1 me te 1:5. Kei waho atu i tenei awhe, he pai ake nga arotahi plano-convex.
Ko nga arotahi ZnSe e tino pai ana mo te whakamahi me nga laser CO2 mana nui. Ka tukuna e Paralight Optics nga Arotahi Bi-Convex Zinc Selenide (ZnSe) me te paninga AR aunui kua arotauhia mo te 8 ki te 12 μm awhe matakite kua whakatakotoria ki runga i nga mata e rua. Ko tenei paninga ka tino whakaiti i te whakaata o te mata teitei o te tïpako, ka puta te tuku toharite neke atu i te 97% i runga i te awhe paninga AR katoa. Tirohia nga Kauwhata e whai ake nei mo o tohutoro.
