Description
One type of optical Aberration of a lens with spherical surface. When coma aberration occurs, the image cannot be focused because the light rays no longer meet at the focal plane as a point but rather as the shape of a comet. Coma is caused by various lens zones having different magnifications. A lens systems that is corrected for both Spherical aberration and coma for a single object position is called Aplanatic.
