Zinc Selenide
Ma Lens a Meniscus Oipa

Ma lens a Meniscus amagwiritsidwa ntchito kwambiri poyang'ana kukula kwa mawanga ang'onoang'ono kapena kugwiritsa ntchito zolumikizana.Amapereka magwiridwe antchito apamwamba kwambiri pochepetsa kwambiri zozungulira zozungulira.Negative meniscus (convex-concave) magalasi, omwe amakhala ndi malo owoneka bwino komanso opindika ndipo amakhala ocheperako pakati kuposa m'mphepete & amachititsa kuti kuwala kwa kuwala kuphatikizepo, adapangidwa kuti achepetse kufalikira kwa spherical mu mawonekedwe a kuwala.

Akagwiritsidwa ntchito kupatutsa kuwala mu ntchito zokulitsa, malo opindika amayenera kuyang'anizana ndi mtengowo kuti achepetse kuzungulira kozungulira.Ikagwiritsidwa ntchito limodzi ndi mandala ena, lens yoyipa ya meniscus imakulitsa kutalika kwapakati ndikuchepetsa kabowo ka manambala (NA) kachitidwe.

Magalasi a ZnSe ndi abwino kugwiritsa ntchito ma lasers a CO2 chifukwa cha mawonekedwe abwino kwambiri azithunzi komanso kukana kugwedezeka kwamafuta.Paralight Optics imapereka magalasi a meniscus a Zinc Selenide (ZnSe), magalasi awa amachepetsa NA ya makina owoneka bwino ndipo amapezeka ndi zokutira zotsutsana ndi zowonera, zomwe zimapangidwira mawonekedwe a 8 µm mpaka 12 μm omwe amayikidwa pamalo onse ndi zokolola. kufalikira kwapakati kupitirira 97% pamtundu wonse wa zokutira za AR.
