Zinc Selenide (ZnSe)
Arotahi Plano-Convex
Ko nga arotahi mahere-convex ka iti ake te porowhita porowhita i te wa e aro ana ki te kore mutunga (i te wa kei tawhiti te mea whakaahua me te teitei o te tauwehenga conjugate).Na reira ko ratou te arotahi ki nga kamera me nga telescopes.Ka tutuki te tino pai ina anga te mata o te plano ki te papa rererangi e hiahiatia ana, ara, ka anga te mata kōpiko ki te kurupae maiki kua tuituia.He pai te kowhiringa mo te whakahiato marama, mo te arotahi ranei i nga tono e whakamahi ana i te whakamarama monochromatic, i roto i nga umanga penei i te ahumahi, rongoa, robotics, arai ranei.He whiringa ohaoha mo nga tono tono na te mea he ngawari ki te hanga.Ko te tikanga, he pai te mahi o nga arotahi plano-convex i te wa e noho ana te ahanoa me te atahanga ki nga owehenga whakakotahi tino > 5:1, <1:5 ranei, no reira ka iti haere te rerekee porohita, te koma me te korikori.Ina kei waenganui i enei uara e rua te whakanuinga tino hiahia, ka pai ake nga arotahi Bi-convex.
Ko nga arotahi ZnSe te nuinga o te whakamahi i roto i te whakaahua IR, te koiora, me nga tono hoia, he pai mo te whakamahi me nga laser CO2 mana nui na te iti o te whakaurunga.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 whakamaarama whero.Ko te Paralight Optics e tuku ana i te Zinc Selenide (ZnSe) Plano-Convex (PCV) Arotahi e waatea ana me te paninga AR aunui kua arotauhia mo te 2 µm – 13 μm, 4.5 – 7.5 μm ranei, 8 – 12 μm awhe matakite kei runga i nga mata e rua.Ko tenei paninga ka tino whakaiti i te whakaata toharite o te tïpako iti iho i te 3.5%, ka puta te tuku toharite neke atu i te 92%, 97% ranei puta noa i te awhe paninga AR katoa.Tirohia nga Kauwhata e whai ake nei mo o tohutoro.
