Representation of Wavefront Aberrations
... In everyday life we measure distances in physical units of meters. However, in optics it is common to measure distances with a ruler that is calibrated in wavelengths of light. Such a ruler effectively measures the number of times light must oscillate in traveling from the object to the image. If al ...

Optical aberration
.svg?width=300)
An optical aberration is a departure of the performance of an optical system from the predictions of paraxial optics. In an imaging system, it occurs when light from one point of an object does not converge into (or does not diverge from) a single point after transmission through the system. Aberrations occur because the simple paraxial theory is not a completely accurate model of the effect of an optical system on light, rather than due to flaws in the optical elements.Aberration leads to blurring of the image produced by an image-forming optical system. Makers of optical instruments need to correct optical systems to compensate for aberration.The articles on reflection, refraction and caustics discuss the general features of reflected and refracted rays.
