Zinc Selenide (ZnSe)
Magalasi a Plano-Convex
Magalasi a plano-convex amapereka kupotoza kocheperako poyang'ana mopanda malire (pamene chinthu chojambulidwa chili patali ndipo chiŵerengero cha conjugate ndichokwera). Chifukwa chake ndi ma lens opita ku makamera ndi ma telescopes. Kuchita bwino kwambiri kumachitika pamene plano pamwamba ikuyang'anizana ndi ndege yomwe ikufunidwa, mwa kuyankhula kwina, malo opindika amayang'ana pamtengo wopindika. Magalasi a Plano convex ndi chisankho chabwino pakuwombana kopepuka kapena kuyang'ana kwambiri pakugwiritsa ntchito kuwunikira kwa monochromatic, m'mafakitale monga mafakitale, mankhwala, robotics, kapena chitetezo. Iwo ndi chisankho chandalama pazovuta zofunsira chifukwa ndizosavuta kupanga. Monga lamulo la chala chachikulu, magalasi a plano-convex amachita bwino pamene chinthucho ndi chithunzicho zili mtheradi conjugate ratios> 5: 1 kapena <1: 5, kotero spherical aberration, coma ndi kupotoza zimachepetsedwa. Pamene kukulitsa kofunikira kuli pakati pa zikhalidwe ziwirizi, magalasi a Bi-convex nthawi zambiri amakhala oyenera.
Magalasi a ZnSe amagwiritsidwa ntchito kwambiri pojambula zithunzi za IR, biomedical, ndi ntchito zankhondo, ndizoyenera kugwiritsidwa ntchito ndi ma laser amphamvu kwambiri a CO2 chifukwa cha kuchepa kwa mphamvu. Kuonjezera apo, angapereke kufalitsa kokwanira m'dera lowoneka kuti alole kugwiritsa ntchito mtanda wofiira. Paralight Optics imapereka Magalasi a Zinc Selenide (ZnSe) Plano-Convex (PCV) omwe amapezeka ndi zokutira zamtundu wa Broadband AR zokongoletsedwa ndi 2 µm - 13 μm kapena 4.5 - 7.5 μm kapena 8 - 12 μm zosawoneka bwino zoyikidwa pamalo onse awiri. Kupaka uku kumachepetsa kwambiri mawonekedwe a gawo lapansi lochepera 3.5%, kutulutsa mpweya wopitilira 92% kapena 97% pamitundu yonse ya zokutira za AR. Yang'anani m'ma Grafu otsatirawa kuti mupeze zolozera zanu.
