ABERRATION, CHROMATIC

A defect in a lens or optical system due to the greater refraction of shorter wavelengths over that of loner ones at a lens surface. Hence the focal length of a simple lens is shorter for blue than for red rays. This dispersion of the wave-lengths will reason colour fringes in the image field of a lens with such an aberration.
