Aberration in optical systems
ABERRATION IN OPTICAL SYSTEMS The aberrations in optical systems ( lenses , prisms , mirrors or a combination thereof in order to produce an image go to image degradation. It occurs when light from a point of an object does not converge to (or diverges from a) a single point then transmitted through the system. Instrumentalists fix these systems need to compensate for aberrations. Overview Aberrations are divided into two categories: Monochromatic aberrations , which are produced without dispersion . These include aberrations in reflective surfaces of any color (or wavelength , according to the region of the electromagnetic spectrum in which it is working), and monochromatic aberrations of a single wavelength. Chromatic aberration , where a system disperses the different wavelengths of light.
