A color distortion defect in a lens system. Chromatic aberration is the inability of a lens to bring varying wavelengths of radiation to a common point of focus. It is caused by refractive index variations. White light passing through a single lens will arrive at the image plane with the wavelengths from the blue end of the spectrum focused at a shorter distance than the wavelengths from the red end of the spectrum. The resultant image will have colored edges.
