Spherical Aberration Image

Spherical Aberration Image. The most serious of the classical seidel monochromatic lens aberrations that occurs with. Spherical aberration is an optical aberration that results when the paraxial and marginal rays have different focal lengths.

Image quality from lenses with large apertures (small f/#s) are more likely to suffer from spherical aberration, because of this larger angle of incidence. Spherical aberration generally reduces retinal image contrast and affects visual quality, especially under mesopic conditions.
