Lens ya aspheric cyangwa asphere (bikunze kwitwa ASPH kumpande zijisho) ni lens ifite imyirondoro yubuso ntabwo ari igice cyumuzingi cyangwa silinderi.Umwirondoro wa asphere urushijeho kuba mwiza urashobora kugabanya cyangwa gukuraho aberrasi ya serefegitire kandi ukanagabanya izindi optique nka astigmatism, ugereranije ninzira yoroshye.Lens imwe ya aspheric irashobora gusimbuza sisitemu nyinshi igoye cyane.Igikoresho cyavuyemo ni gito kandi cyoroshye, kandi rimwe na rimwe bihendutse kuruta igishushanyo mbonera.Ibintu bya asiferi bikoreshwa mugushushanya ibintu byinshi bigari-ngari kandi byihuse byihuta kugirango bigabanye.Zikoreshwa kandi zifatanije nibintu byerekana (sisitemu ya catadioptric) nka plaque ikosora ya Schmidt ikoreshwa muri kamera ya Schmidt na telesikopi ya Schmidt - Cassegrain.Utubumbe duto duto duto dukoreshwa mugukusanya diode laseri.Lens ya asiferi nayo rimwe na rimwe ikoreshwa mu ndorerwamo z'amaso.Indorerwamo z'amaso ya Aspheric zituma habaho iyerekwa ryoroshye kuruta linzira isanzwe "nziza", cyane cyane iyo urebye mubindi byerekezo bitari lens optique.Byongeye kandi, kugabanya ingaruka zo gukuza lens birashobora gufasha mubitabo bifite imbaraga zitandukanye mumaso 2 (anisometropia).Ntaho bihuriye nubwiza bwa optique, barashobora gutanga lens yoroheje, kandi bakanahindura amaso yabarebaga gake nkuko bigaragara kubandi bantu, bikabyara isura nziza.
2.Spherical vs aspherical lens

Indorerwamo ya Asiferique ikoresha umurongo utandukanye hejuru yubuso bwabo kugirango ugabanye ubwinshi kandi ube mwiza muburyo bwabo.Lens ya spherical ikoresha umurongo umwe muburyo bwabo, bigatuma byoroha ariko binini, cyane cyane hagati yinzira.
3.Ibyiza byo muri Afurika
Ahari truism ikomeye cyane kubijyanye no kwifata ni uko iyerekwa rinyuze mumurongo wegereye iyerekwa risanzwe.Igishushanyo mbonera cyemerera umurongo shingiro gukoreshwa gukoreshwa utabangamiye imikorere ya optique.Itandukaniro ryibanze hagati ya sereferi na lensifike ni uko lens ya spherical lens ifite curvature imwe kandi ikorwa nka basketball.Lens ya aspheric iragabanuka buhoro buhoro, nkumupira wamaguru hepfo.Lens ya aspheric igabanya gukura kugirango igaragare neza kandi igabanuka ryikigero cyo hagati ikoresha ibikoresho bike, bikavamo uburemere buke.
