Optics aberration
In optics, chromatic aberration (CA), also called chromatic distortion and spherochromatism, is a failure of a lens to focus all colors to the same point. It is caused by dispersion: the refractive index of the lens elements varies with the wavelength of light. The refractive index of most transparent materials decreases with increasing wavelength. Since the focal length of a lens depends …

WebFeb 19, 2024 · An optical aberration refers to a defect in a lens design which causes light to spread out instead of focusing to form a sharp image. This ranges from all the light in an image to only certain spots or edges being out of focus. There are several types of optical aberrations that can occur when imaging. WebThere are five monochromatic aberrations: spherical aberration, coma, astigmatism, Petzval field curvature, and distortion. Each can be present even if the optical system is being used with monochromatic light, e.g. a laser. They differ in appearance and their dependence on f/# and field height (distance from the optical axis).
