Zinc Selenide (ZnSe)
Arotahi Bi-Concave
I te wa e whakatau ana i waenga i te arotahi plan-concave me te arotahi rua-concave, na enei mea e rua ka rereke te marama o te maiki, he pai ake te whiriwhiri i te arotahi rua-concave mena ko te ōwehenga whakakotahitanga (te tawhiti ahanoa ka wehea ki te tawhiti atahanga) he tata ki te 1. Ina he iti iho i te 0.2, nui ake ranei i te 5 te whakanuinga e hiahiatia ana, ko te tikanga ko te whiriwhiri i te arotahi plano-concave.
Ko nga arotahi ZnSe e tino pai ana mo te whakamahi me nga laser CO2 mana nui.Ko te Paralight Optics e tuku ana i te Zinc Selenide (ZnSe) Bi-Concave or Double-Concave (DCV) Arotahi e waatea ana me te paninga AR aunui kua arotauhia mo te 8 - 12 μm awhe matakite kua whakatakotoria ki runga i nga mata e rua.Ko tenei paninga ka tino whakaiti i te whakaatanga teitei o te mata o te tïpako, ka puta te tuku toharite neke atu i te 97% puta noa i te awhe paninga AR katoa.Mo etahi atu korero mo te paninga, tirohia nga Kauwhata e whai ake nei mo o tohutoro.
Āhuatanga:
Rauemi:
Zinc Selenide (ZnSe)
Kōwhiringa paninga:
E waatea ana kaore i pania me nga paninga Antireflection ranei
Roa Arotahi:
Kei te waatea mai i -25.4mm ki -200 mm
Nga tono:
He pai mo CO2 Nga Whakamahi Taiaho Na te iti o te whakaurunga
Whakatakotoranga noa:
Tuhi Tohutoro mo
Matarua-Concave (DCV) Arotahi

Tuhipoka: Ko te roa o te arotahi ka whakatauhia mai i te rererangi matua o muri, kaore i te hono ki te matotoru o te tapa.
