spherical aberration

Spherical aberration is an optical aberration that occurs when light rays passing through a lens or curved optical surface do not converge or diverge to a single focal point. Instead of focusing to a sharp point, the rays focus at different distances from the lens, resulting in a blurred or distorted image. This phenomenon is caused by the inherent shape of spherical lenses or mirrors, which have a spherical (curved) surface. In a lens with spherical aberration: Peripheral rays focus...
