Geometrical Optics
... Aberrations are imperfections in the optical image formed by a spherical lens (or optical mirror). There are five main aberrations: 1. Chromatic aberration. The refractive index of glass varies with wavelength. This results in different focal lengths and image magnifications for different colours. ...
