aberration, chromatic (medicine)


aberration, chromatic
<optics> 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 cause colour fringes in the image field of a lens with such an aberration.
