| spherical aberration |
A lens fault which results in degraded image quality at the film plane. It is caused by light rays passing through the lens from a single point on the optical axis focused at different points according to incident height. Spherical aberration can be reduced by stopping down the lens.

| spherical aberration |
Light passing through a convex lens will be brought to different focus depending upon whether the light passes through near the center of the lens or closer to the periphery. Lens designers strive to correct this kind of zonal aberration to bring peripheral and near-central rays to a common focus.
