Refractive index — Refraction of light at the interface between two media. In optics the refractive index or index of refraction of a substance or medium is a measure of the speed of light in that medium. It is expressed as a ratio of the speed of light in vacuum… … Wikipedia
Aberration of light — Light from location 1 will appear to be coming from location 2 for a moving telescope due to the finite speed of light, a phenomenon known as the aberration of light. The aberration of light (also referred to as astronomical aberration or stellar … Wikipedia

Chromatic aberration — On top is corner detail in a photograph taken with a higher quality lens; bottom is a similar photograph taken with a wide angle lens showing severe visible lateral chromatic aberration. The effect is pronounced on the right side of the building… … Wikipedia
chromatic aberration — Optics. the variation of either the focal length or the magnification of a lens system with different wavelengths of light, characterized by prismatic coloring at the edges of the optical image and color distortion within it. Also called… … Universalium
Spherical aberration — shape of lenses and mirrors. This is an important effect, as spherical shapes are much easier to produce than aspherical and so most lenses have spherical shapes. Positive spherical aberration means peripheral rays are bent too much. Negative… … Wikipedia
chromatic aberration — n aberration caused by differences in the refraction of light at different frequencies * * * unequal deviation of light rays of different wavelengths passing through a refractive medium, resulting in fringes of color around the image produced;… … Medical dictionary
