WebComa. Coma is an aberration which causes rays from an off-axis point of light in the object plane to create a trailing "comet-like" blur directed away from the optic axis (for positive coma). A lens with considerable coma may produce a sharp image in the center of the field, but become increasingly blurred toward the edges. WebShortcomings such as these in an optical system cause what are called optical aberrations. The best-known aberrations include spherical aberration and coma. [4] However there may be more complex sources of aberrations such as in a large telescope due to spatial variations in the index of refraction of the atmosphere.
