Chromatic aberration Definition & Meaning Dictionary.com
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 … See more There are two types of chromatic aberration: axial (longitudinal), and transverse (lateral). Axial aberration occurs when different wavelengths of light are focused at different distances from the lens (focus shift). … See more In some circumstances, it is possible to correct some of the effects of chromatic aberration in digital post-processing. However, in real-world circumstances, chromatic aberration results in permanent loss of some image detail. Detailed knowledge of the … See more Chromatic aberration also affects electron microscopy, although instead of different colors having different focal points, different electron energies may have different focal points. See more In the earliest uses of lenses, chromatic aberration was reduced by increasing the focal length of the lens where possible. For example, this … See more The term "purple fringing" is commonly used in photography, although not all purple fringing can be attributed to chromatic aberration. Similar colored fringing around … See more • Methods to correct chromatic aberrations in lens design • Explanation of chromatic aberration by Paul van Walree See more Weblongitudinal (axial) chromatic aberration.
