Zinc Selenide (ZnSe)
Nā Lens Meniscus maikaʻi

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 (convex-concave), nona ka ʻili convex a me ka ʻili concave a ʻoi aku ka mānoanoa o ka waena ma mua o nā ʻaoʻao a hoʻohuli i nā kukuna māmā, ua hoʻolālā ʻia e hōʻemi i ka aberration spherical i nā ʻōnaehana optical. Ke hoʻohana ʻia e kālele i ke kukui i hui ʻia, pono ka ʻaoʻao convex o ka lens e kū pono i ke kumu e hōʻemi ai i ka aberration spherical. Ke hoʻohana pū ʻia me kahi lens ʻē aʻe, e hoʻopōkole ka lens meniscus maikaʻi i ka lōʻihi kikoʻī a hoʻonui i ka puka helu (NA) o ka ʻōnaehana me ka ʻole o ka hoʻokomo ʻana i ka aberration spherical nui. No ka mea, ʻoi aku ka nui o ka radius meniscus maikaʻi o ka curvature ma ka ʻaoʻao concave o ka lens ma mua o ka ʻaoʻao convex, hiki ke hana ʻia nā kiʻi maoli.

Ua kūpono loa nā lens ZnSe no ka hoʻohana ʻana me nā laser CO2 mana kiʻekiʻe. Ma muli o ke kiʻekiʻe refractive index o ZnSe, hiki iā mākou ke hāʻawi i ka hoʻolālā spherical maikaʻi loa no ZnSe, ʻo ia ka hoʻolālā meniscus maikaʻi. Hoʻokumu kēia mau lens i nā aberrations liʻiliʻi, ka nui o nā kiko, a me nā hewa alo nalu e hoʻohālikelike ʻia me nā lens maikaʻi loa i hana ʻia e nā mea ʻē aʻe.

Hāʻawi ʻo Paralight Optics iā Zinc Selenide (ZnSe) Positive Meniscus Lenses i loaʻa me kahi uhi AR broadband i hoʻopaʻa ʻia no ka 8 µm a 12 μm spectral range i waiho ʻia ma nā ʻaoʻao ʻelua. Hoʻemi nui kēia uhi ʻana i ka noʻonoʻo ʻana o ka ʻili kiʻekiʻe o ka substrate, e hāʻawi ana i ka hoʻoili awelika ma mua o 97% ma luna o ka laulā uhi AR āpau.
