Zinc Selenide (ZnSe)
Nā Lens Bi-Concave

Loaʻa ʻino ka lōʻihi o nā lens Bi-concave a i ʻole Double-concave (DCV). Hiki ke hoʻohana ʻia kēia mau lens diverging no ka hoʻokaʻawale ʻana i kahi kaola i hui pū ʻia i kahi hiʻohiʻona virtual a hoʻohana mau ʻia i loko o kahi mea hoʻonui beam ʻano Galilaia. Hoʻohana pinepine ʻia lākou e hoʻokaʻawale a hoʻonui paha i ka ʻokoʻa o kahi kaola hoʻohuli. I loko o nā ʻōnaehana optical, he mea maʻamau i ka poʻe noiʻi ke koho pono i kā lākou optics i hiki ke hoʻopau ʻia nā aberrations i hoʻokomo ʻia e nā lens lōʻihi kūpono a maikaʻi ʻole. Hoʻohana ka poʻe i kēia mau lens i ʻelua e hoʻonui i ka lōʻihi kūpono o ka lens converging e like me ka lens meniscus maikaʻi ʻole.

I ka hoʻoholo ʻana ma waena o ka lens plano-concave a me ka lens bi-concave, ʻo ia mau mea ʻelua e hoʻokaʻawale ai ka mālamalama hanana, ʻoi aku ka maikaʻi o ke koho ʻana i kahi lens bi-concave inā ʻo ka ratio conjugate piha (ka mamao mea i puʻunaue ʻia e ka mamao kiʻi) kokoke i ka 1. Ke emi iho ka hoonui piha i makemakeia ma ka 0.2 a oi aku paha mamua o 5, o ka manao ke koho i ka lens plano-concave.

Ua kūpono loa nā lens ZnSe no ka hoʻohana ʻana me nā laser CO2 mana kiʻekiʻe. Hāʻawi ʻo Paralight Optics i nā Lenses Zinc Selenide (ZnSe) Bi-Concave a i ʻole Double-Concave (DCV) i loaʻa me kahi uhi AR broadband i hoʻopaʻa ʻia no ka laulā spectral 8 - 12 μm 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 i ʻoi aku ma mua o 97% ma waena o ka laulā uhi AR āpau. No ka ʻike hou aku e pili ana i ka uhi ʻana, e ʻoluʻolu e nānā i nā kiʻi ma lalo nei no kāu mau kuhikuhi.
