Zinc Selenide (ZnSe)
Nā Lens Plano-Concave

ʻO nā lens plano-concave nā lens maikaʻi ʻole i ʻoi aku ka mānoanoa ma ka ʻaoʻao ma mua o ka waena, ke hele ka mālamalama ma o lākou, ʻokoʻa ia a ʻo ke kiko kikoʻī he virtual.ʻAʻole maikaʻi ko lākou mau kikoʻī, a me ka radius o ka curvature o nā ʻaoʻao curved.Hāʻawi ʻia i kā lākou aberration spherical maikaʻi ʻole, hiki ke hoʻohana ʻia nā lens plano-concave e kaulike i nā aberrations spherical i hana ʻia e nā lens ʻē aʻe i loko o kahi ʻōnaehana optical.Pono nā lens plano-concave no ka hoʻokaʻawale ʻana i ke kukui i hui ʻia a me ka hoʻohui ʻana i kahi kukuna convergent, hoʻohana ʻia lākou e hoʻonui i nā kukuna māmā a hoʻonui i ka lōʻihi o ke kiko i nā ʻōnaehana optical e kū nei.Hoʻohana pinepine ʻia kēia mau lens maikaʻi ʻole i nā telescopes, nā kamera, nā lasers a i ʻole nā aniani e kōkua i nā ʻōnaehana hoʻonui e ʻoi aku ka paʻakikī.

Hana maikaʻi nā lens plano-concave ke loaʻa ka mea a me ke kiʻi i nā ratio conjugate piha, ʻoi aku ka nui ma mua o 5:1 a i ʻole ka liʻiliʻi ma mua o 1:5.I kēia hihia, hiki ke hōʻemi i ka aberration spherical, coma, a me ka distortion.E like me nā lens plano-convex, no ka hoʻokō ʻana i ka pono kiʻekiʻe o ka ʻili curved e kū pono i ka mamao mea nui a i ʻole ka conjugate pau ʻole e hōʻemi i ka spherical aberration (koe wale nō ke hoʻohana ʻia me nā lasers ikaika nui kahi e hoʻohuli ʻia ai kēia e hoʻopau i ka hiki o kahi virtual. nānā).

Ua kūpono loa nā lens ZnSe no ka hoʻohana ʻana me nā laser mana kiʻekiʻe CO a i ʻole CO2.Eia kekahi, hiki iā lākou ke hāʻawi i ka hoʻouna ʻana ma ka ʻāpana ʻike ʻia e ʻae i ka hoʻohana ʻana i kahi kukui alignment ʻike ʻia, ʻoiai ʻoi aku ka nui o ka hoʻohālikelike ʻana i hope.Hāʻawi ʻo Paralight Optics iā Zinc Selenide (ZnSe) Plano-Concave (PCV) Lenses i loaʻa me kahi uhi AR broadband i hoʻopaʻa ʻia no ka 2 µm - 13 μm a i ʻole 4.5 - 7.5 μm a i ʻole 8 - 12 μm kikoʻī kikoʻī i waiho ʻia ma nā ʻaoʻao ʻelua.Hoʻemi nui kēia uhi ʻana i ka noʻonoʻo kiʻekiʻe o ka ʻili o ka substrate, e hāʻawi ana i ka hoʻoili awelika i ʻoi aku ma mua o 92% a i ʻole 97% ma waena o ka laulā uhi AR āpau.E nānā i nā kiʻi no kāu mau kuhikuhi.
