N-BK7 (CDGM H-K9L)
Magalasi Owoneka Bwino Kwambiri

Kwa magalasi ozungulira, kutalika kwake kokhazikika kumatha kufotokozedwa ndi kuphatikiza kopitilira kumodzi kwa ma radii akutsogolo ndi kumbuyo kwa kupindika.Kuphatikizika kulikonse kwa mapindikidwe apamtunda kumapangitsa kuti pakhale kusiyana kosiyana komwe kumachitika chifukwa cha lens.Ma radius opindika pamtundu uliwonse wa ma lens amawonekedwe abwino adapangidwa kuti achepetse kuzungulira kozungulira komanso chikomokere chomwe chimapangidwa ndi mandala, ndikuchikulitsa kuti chigwiritsidwe ntchito pama conjugates opanda malire.Izi zimapangitsa kuti magalasi awa akhale okwera mtengo kuposa magalasi a plano-convex kapena bi-convex, komabe amakhala otsika mtengo kuposa magalasi athu opukutidwa a CNC kapena ma achromats.

Popeza magalasi amakongoletsedwa ndi kukula kochepa kwa malo, amatha kufikira magwiridwe antchito ang'onoang'ono a ma diameter ang'onoang'ono.Kuti mugwire bwino ntchito poyang'ana ntchito, ikani pamwamba ndi utali wopindika waufupi (ie, pamwamba pake mokhotakhota kwambiri) kulowera komwe kumachokera.

Paralight Optics imapereka magalasi a N-BK7 (CDGM H-K9L) Owoneka Bwino Kwambiri omwe adapangidwa kuti achepetse kufalikira kozungulira pomwe akugwiritsabe ntchito malo ozungulira kupanga mandala.Amagwiritsidwa ntchito pama conjugates opanda malire pamapulogalamu amphamvu kwambiri pomwe zowirikiza sizosankha.Ma lens akupezeka osaphimbidwa kapena zokutira zathu za antireflection (AR) zomwe zimayikidwa pamalo onse awiri kuti achepetse kuwala komwe kumawonekera kuchokera kumtundu uliwonse wa mandala kuti achepetse kuchuluka kwa kuwala komwe kumawonekera kuchokera pagawo lililonse la lens.Zovala za AR izi zimakongoletsedwa ndi mawonekedwe a 350 - 700 nm (VIS), 650 - 1050 nm (NIR), 1050 - 1700 nm (IR).Kupaka uku kumachepetsa kuwunikira kwakukulu kwa gawo lapansi kuchepera 0.5% pamtunda uliwonse, kumapereka kufalikira kwapakati pamitundu yonse ya zokutira za AR.Yang'anani m'ma Grafu otsatirawa kuti mupeze zolozera zanu.
