Zinc Selenide
Nga Arotahi Meniscus Kino
Ina whakamahia ki te wehe i te marama i roto i nga tono whakawhanui kurupae, me anga te mata concave ki te kurupae hei whakaiti i te rerekee porohita. Ina whakamahia tahi me tetahi atu arotahi, ka piki ake te roa o te arotahi me te whakaiti i te aperture tau (NA) o te punaha.
He pai nga arotahi ZnSe mo te tono lasers CO2 na te pai o nga ahuatanga atahanga me te kaha o te aukati ki te wia wera. Ka tukuna e Paralight Optics nga arotahi meniscus kino o Zinc Selenide (ZnSe), ka whakaitihia e enei arotahi te NA o te punaha whatu, ka waatea me te paninga arai-whakaata aunui, he mea pai mo te 8 µm ki te 12 μm awhe spectral kua whakatakotoria ki runga i nga mata e rua me nga hua. he tuku toharite neke atu i te 97% i runga i te whānuitanga whakakikorua AR katoa.
Āhuatanga:

Zinc Selenide (ZnSe)
Kōwhiringa paninga:
Kore i whakakikoruatia me te paninga Antireflection ranei
Roa Arotahi:
Kei te waatea mai i -40 ki -1000 mm
Taupānga:
Hei Whakaheke i te NA o tetahi Pūnaha Optical
Whakatakotoranga noa:
Tuhi Tohutoro mo
