spherical aberration in mirrors is usually corrected by using a mirror which is not a sphere. a parabolic mirror is often used instead of a spherical mirror. in lenses, the simplest method for minimizing spherical aberration is to use an aperture in front of the lens. symmetric doublets, such as the orthoscopic doublet, are also efficient in greatly reducing the spherical aberration in lenses.read more≫
