Amalensi e-aspheric anejometri yangaphezulu eyinkimbinkimbi ngenxa yokuthi awalandeli ingxenye yendilinga.Amalensi e-aspheric ayalingana ngokuzungezayo futhi anendawo eyodwa noma ngaphezulu eyi-aspheric ehluka ngomumo ukusuka kuyindilinga.
Inzuzo eyinhloko yama-lens anjalo ukuthi anciphisa kakhulu ukuphuma kwe-spherical.I-Spherical aberration kwenzeka lapho ilensi ingakwazi ukugxilisa konke ukukhanya okungenayo endaweni efanayo ncamashi.Ngenxa yemvelo yomumo womphezulu we-aspheric ongejwayelekile, ivumela ubude begagasi abaningi bokukhanya ukuthi busetshenziswe ngesikhathi esisodwa, okuvumela konke ukukhanya ukuthi kugxile endaweni efanayo, okuholela ezithombeni ezibukhali.
Wonke amalensi ase-aspheric, kungakhathaliseki ukuthi i-convex noma i-concave, awakwazi ukuchazwa nge-radius eyodwa yokugoba, lapho isimo sawo sichazwa ngezibalo ze-Sag, eziguquguqukayo, futhi "k" ichaza umumo usuwonke we-aspheric surface .
Nakuba amalensi ase-aspheric enikeza izinzuzo ezithile ngaphezu kwamalensi avamile, ukumisa kwawo okuhlukile kuwenza kube nzima kakhulu ukuwenza, ngakho abaklami bamehlo kufanele balinganise izinzuzo zokusebenza ngokumelene nezindleko eziphezulu.Izinhlelo zesimanje ze-optical ezisebenzisa izakhi ze-aspheric emiklamo yazo zinganciphisa inani lamalensi adingekayo, okuvumela ukudalwa kwezinhlelo ezilula, ezihlangene, kuyilapho zisagcina futhi zivame ukweqa ukusebenza kwezinhlelo ezisebenzisa izakhi eziyindilinga kuphela.Nakuba ebiza kakhulu kunamalensi avamile, amalensi aspheric angaba enye indlela ekhangayo kanye nenketho enamandla yama-optics asebenza kahle kakhulu.
Indawo ye-aspheric ingenziwa kusetshenziswa izindlela ezahlukahlukene.Isisekelo se-aspheric esiyisisekelo sikhiqizwa ubuchwepheshe bokubumba umjovo, obungakwazi ukubona izinhlobo ezahlukene zezindawo ezizungezile, ikakhulukazi izinhlelo zokusebenza zokugxilisa ukukhanya (insimu yombani).Ama-asphere anembe kakhulu futhi ayinkimbinkimbi adinga ukukhiqizwa nokupholishwa kwe-CNC ehlukene.
Izakhi ze-aspherical, kufaka phakathi ingilazi ye-semi-optical ne-optical, ngisho nezinto zepulasitiki ezifana ne-polycarbonate, i-polyurethane noma i-silicone.
