noun, Optics.
1.
the variation of either the focal length or the magnification of a lens system with different wavelengths of light, characterized by prismatic coloring at the edges of the optical image and color distortion within it.
noun
1.
a defect in a lens system in which different wavelengths of light are focused at different distances because they are refracted through different angles. It produces a blurred image with coloured fringes
