Iilensi ze-aspheric zinejometri yomphezulu entsonkothileyo ngakumbi kuba azilandeli inxalenye yengqukuva.Iilensi ze-aspheric zijikeleza ngokulinganayo kwaye zinendawo enye okanye ngaphezulu kwe-aspheric eyahluke ngokubunjwa kwingqukuva.
Inzuzo ephambili yezo lens kukuba zinciphisa kakhulu i-spherical aberration.I-Spherical aberration yenzeka xa ilensi ingakwazi ukujolisa konke ukukhanya okungenayo kwindawo enye.Ngenxa yobume bomphezulu we-aspheric irregular shape surface, ivumela amaza okukhanya amaninzi ukuba aguqulwe ngaxeshanye, ukuvumela konke ukukhanya ukuba kugxininise kwindawo enye, kubangele imifanekiso ebukhali.
Zonke iilensi ze-aspheric, nokuba i-convex okanye i-concave, ayinakuchazwa ngeradiyasi enye yokugoba, kwimeko apho imilo yazo ichazwa yi-equation ye-Sag, eguquguqukayo, kwaye "k" ichaza ubume buphelele bomphezulu we-aspheric.
Ngelixa iilensi ze-aspheric zibonelela ngeengenelo ezithile ngaphezulu kweelensi eziqhelekileyo, ukwakheka kwazo okwahlukileyo kuzenza kube nzima ngakumbi ukwenza iilensi, ngoko ke abaqulunqi bamehlo kufuneka balinganise iinzuzo zokusebenza ngokuchasene neendleko eziphezulu.Iinkqubo zanamhlanje zamehlo ezisebenzisa i-aspheric element kuyilo lwazo zinokunciphisa inani leelensi ezifunekayo, zivumela ukudalwa kwezinto ezikhaphukhaphu, ezixineneyo, ngelixa zigcina kwaye zihlala zigqithisa ukusebenza kweenkqubo zisebenzisa izinto ezingqukuva kuphela.Nangona zibiza kakhulu kuneelensi eziqhelekileyo, iilensi ze-aspheric zinokuba yinto ekhangayo kunye nokhetho olunamandla kwi-optics yokusebenza okuphezulu.
Umphezulu we-aspheric unokwenziwa kusetyenziswa iindlela ezahlukeneyo.Umphezulu osisiseko we-aspheric uveliswa ngetekhnoloji yokubumba inaliti, enokuqonda iintlobo ezahlukeneyo zemiphezulu ye-aspheric, ngakumbi kwizicelo zokugxila ekukhanyeni (indawo yombane).Ii-asphere ezichaneke ngakumbi nezintsonkothileyo zifuna ukuveliswa okwahlukileyo kwe-CNC kunye nokupholisha.
Izinto ze-aspherical, ezibandakanya iglasi ye-semi-optical kunye ne-optical, kunye nezixhobo zeplastiki ezifana ne-polycarbonate, i-polyurethane okanye i-silicone.
