Zinc Selenide (ZnSe)
Ma Lens abwino a Meniscus

Ma lens a Meniscus amagwiritsidwa ntchito makamaka poyang'ana kukula kwa mawanga ang'onoang'ono kapena mapulogalamu ophatikizana. Amapereka magwiridwe antchito apamwamba kwambiri pochepetsa kwambiri zozungulira zozungulira. Ma lens owoneka bwino a meniscus (convex-concave), omwe amakhala ndi malo opingasa komanso malo opindika ndipo amakhala okulirapo pakati kuposa m'mphepete & kupangitsa kuti kuwala kwa kuwala kuphatikize, adapangidwa kuti achepetse kufalikira kwa mawonekedwe owoneka bwino. Akagwiritsidwa ntchito poyang'ana mtengo wopindika, mbali yowoneka bwino ya disolo iyenera kuyang'ana komwe kumachokera kuti kuchepetse kufalikira kozungulira. Akagwiritsidwa ntchito limodzi ndi mandala ena, lens yabwino ya meniscus idzafupikitsa utali wokhazikika ndikuwonjezera kabowo ka manambala (NA) kachitidweko popanda kuyambitsa kusintha kwakukulu kozungulira. Popeza lens yabwino ya meniscus imakhala ndi utali wopindika kwambiri kumbali ya concave ya mandala kuposa mbali ya convex, zithunzi zenizeni zimatha kupangidwa.

Zopempha Zitsanzo Zopempha za OEM

Magalasi a ZnSe ndiwoyenera kwambiri kugwiritsidwa ntchito ndi ma laser amphamvu kwambiri a CO2. Chifukwa cha kuchuluka kwa refractive index ya ZnSe, titha kupereka mawonekedwe abwino kwambiri ozungulira a ZnSe, omwe ndi mapangidwe abwino a meniscus. Ma lens awa amapangitsa kuti pakhale kusintha pang'ono, kukula kwa mawanga, ndi zolakwika zakutsogolo zofananira ndi magalasi abwino kwambiri opangidwa ndi zida zina.

Paralight Optics imapereka Magalasi a Zinc Selenide (ZnSe) Positive Meniscus omwe amapezeka ndi zokutira za burodibandi za AR zokongoletsedwa ndi mawonekedwe a 8 µm mpaka 12 μm oyikidwa pamalo onse awiri. Kupaka uku kumachepetsa kwambiri kuwunikira kwapamwamba kwa gawo lapansi, kumapereka kufalikira kwapakati pa 97% pamitundu yonse ya zokutira za AR.
