Aberration

An optical fault in a lens that creates a less-than-perfect image.

In optics, the aberration is a property of optical systems, such as lenses that causes light to be spread out over some region of space rather than focused to a point. Aberrations cause the image formed by a lens to be blurred or distorted, with the nature of the distortion depending on the type of aberration.

There are six types of optical aberration:

  • Astigmatism
  • Chromatic Aberration
  • Coma
  • Distortion
  • Field Curvature
  • Spherical Aberration
