Sphere inzvimbo yese ine curvature imwe chete, sekucheka kubva padenderedzwa, uye isiri-sphere inzira yakasiyana, senge pamwe kucheka kubva kune ellipse.Chinangwa che spherical aberration ndechekugadzirisa dambudziko re spherical aberration, nekuti spherical surface ine mafocal point akasiyana e off-axis light rays, zvichikonzera kusaona zvakanaka.
Chekutanga, kugona kugadzira sphere inhanho yekumberi kune indasitiri yekugadzira lens, zvichiita kuti mhinduro dzedu dziwedzere kushanduka.Nekune rimwe divi, iyo isiri-sphere, sekureva kunoita zita, haingori denderedzwa, asi pane zvakawanda zvinogoneka kuti chii chaizvo chimiro chechiso.Saka pane musiyano mukuru pakati peasiri-sphere neasiri-sphere, sezvakangoita curvature gradient ye ellipse yakafanana ichave yakasiyana zvakanyanya zvichienderana nenzvimbo yekucheka, iyo inosarudza mwero wemugadziri wega wega.Saka kana iwe usinganzwe wakasununguka nelenzi usaramba tekinoroji, zvinogona kunge zviri kuti mugadziri welenzi ari kushandisa dhizaini isina kufanira iwe.Mukuongorora kwekupedzisira, zvinotarisirwa kuti iyo imaging deformation ye-off-center area ichava duku.Kazhinji, vagadziri vanoshandisa avhareji maparameter eboka revanhu, ayo ane hukama nedaro pakati pemeso nelenzi (kureba kwemhino, kudzika kweorbital), uye geometry yekutenderera kweziso.Izvi zvinogona kuitika kana ma parameter ako akasiyana zvakanyanya kubva kune madhizaini anoshandiswa.
Mukugadzirwa kwemaziso e-lens, ukuru hwelens uye kuoma kwemaitiro kunogona kuderedzwa zvakanyanya nekuita kwema-lens akawanda muchidimbu chimwe chete, asi dhizaini nekugadzirisa zvinodiwa zveiyi lens zvakakwirira.
Yakanakira chiono ichokwadi "chaiyo isiri-sphere".Asi hazvina basa kana sphere INODZORA kune zvakasikwa, kuenzanisa chiono chinhu chinomiririra, chero bedzi chiri kugadzikana.
