In optics, the aberration is a flaw in the imaging properties of optical systems such as lenses or mirrors, that causes light to be blurred, distorted or spread out over some region of space rather than focused to a point.
Types of aberration
- defocus aberration;
- chromatic aberration (a problem restricted to lenses);
- comatic aberration (or coma);
- petzval field curvature;
- spherical aberration.
