Zinc Selenide (ZnSe)
Arotahi Plano-Concave
He pai te mahi o nga arotahi mahere-concave i te wa e noho ana te ahanoa me te atahanga ki nga owehenga honohono tino, nui ake i te 5:1, iti iho ranei i te 1:5.I roto i tenei take, ka taea te whakaiti i te aberration porowhita, coma, me te distortion.He rite ano ki nga arotahi plan-convex, hei whakatutuki i te tino pai o te mata kopikopiko me anga atu ki te tawhiti rawa atu, ki te conjugate mutunga kore ranei hei whakaiti i te rerekee porohita (haunga ka whakamahia me nga laser hiko teitei me huri tenei ki te whakakore i te tupono o te mariko. arotahi).
Ko nga arotahi ZnSe e tino pai ana mo te whakamahi me nga laser hiko CO, CO2 ranei.I tua atu, ka taea e ratou te whakarato i te nui o te tuku i roto i te rohe e kitea ana kia taea ai te whakamahi i te kurupae tirohanga kitea, ahakoa ka kaha ake te whakahua o nga whakaata o muri.Ko te Paralight Optics e tuku Zinc Selenide (ZnSe) Plano-Concave (PCV) Arotahi e waatea ana me te paninga AR aunui kua arotauhia mo te 2 µm – 13 µm, 4.5 – 7.5 µm, 8 – 12 µm ranei te awhe matakite kua whakatakotoria ki 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 92%, 97% ranei puta noa i te awhe paninga AR katoa.Tirohia nga Kauwhata mo o tohutoro.
