Zinc Selenide
Nā Lens Meniscus ʻino

Hoʻohana mua ʻia nā lens Meniscus no ka nānā ʻana i nā wahi liʻiliʻi a i ʻole nā ​​noi collimation.Hāʻawi lākou i ka hana ʻoi aku ka maikaʻi ma ka hōʻemi nui ʻana i nā aberrations spherical.ʻO nā lens meniscus maikaʻi ʻole (convex-concave), nona ka ʻili convex a me ka ʻili concave a ʻoi aku ka lahilahi ma waena ma mua o nā ʻaoʻao a e hoʻokaʻawale i nā kukuna māmā, ua hoʻolālā ʻia e hōʻemi i ka aberration spherical i nā ʻōnaehana optical.

Ke hoʻohana ʻia e hoʻokaʻawale i ka mālamalama i nā noi hoʻonui beam, pono ke alo o ka concave i ke kukui e hōʻemi i ka aberration spherical.Ke hoʻohana pū ʻia me kahi lens ʻē aʻe, e hoʻonui ka lens meniscus maikaʻi ʻole i ka lōʻihi o ke kiko a hoʻemi i ka puka helu (NA) o ka ʻōnaehana.

He kūpono nā lens ZnSe no ka hoʻohana ʻana i nā lasers CO2 ma muli o nā hiʻohiʻona kiʻi maikaʻi loa a me ke kūpaʻa kiʻekiʻe i ka haʻalulu wela.Hāʻawi ʻo Paralight Optics i nā lens meniscus maikaʻi ʻole ʻo Zinc Selenide (ZnSe), hoʻemi kēia mau lens i ka NA o kahi ʻōnaehana optical a loaʻa me kahi uhi anti-reflection broadband, i hoʻopaʻa ʻia no ka 8 µm a 12 μm spectral range i waiho ʻia ma nā ʻaoʻao ʻelua a me nā hua. ka awelika hoʻoili ma mua o 97% ma luna o ka laulā uhi AR holoʻokoʻa.
