Aberration: A lens fault (problem) in which light rays are scattered, degrading the image. Different types include: chromatic (colors and light wavelengths), spherical (blurring in the center of a picture), coma (edge blurring), astigmatism (light rays focused as a line, not a point), and field curvature (plane of sharpest focus is a curved surface).
Achromatic Lens: a lens constructed of different types of glass, used to reduce chromatic aberration.
