chromatic aberration

n.
Deficiency in clarity of an image produced by a lens, caused by the inability of the lens to bring all colors of light to a focus at the same point. Also called false color.

chromatic aberration

n
(Astronomy) a defect in a lens system in which different wavelengths of light are focused at different distances because they are refracted through different angles. It produces a blurred image with coloured fringes

chromat′ic aberra′tion


n.
the variation of either the focal length or the magnification of a lens system with different wavelengths of light.

References in classic literature ?
To suppose that the eye, with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree.
The objectives correct for spherical and chromatic aberrations for the visible and the NIR spectra.
Infinity Corrected, Have No Chromatic Aberrations, And Are Mirror Based In Construction.
In addition, precision mirror optics eliminate chromatic aberrations.
Designed to correct lateral and axial chromatic aberrations over the entire field of view, these objectives produce images that are crisp, flat and clear with high contrast and high resolution
Emitted LED light is focused, leveraging the company's patented mirror technology, to achieve optimal light shape and spectral homogeneity in the illumination focus range, resulting in no chromatic aberrations.
The honour is being conferred upon Panasonic in recognition of the company's development of In-Camera Electronic Compensation for Lateral Chromatic Aberrations in External Lenses.
system uses two lenses to minimise both distortion and chromatic aberrations.
The lens also includes two ED lens elements and one Super ED lens element for increased performance and effective control against chromatic aberrations along with FUJINON's proprietary HT-EBC coating on the entire lens surface to effectively prevent reflections, and control flare and ghosting.
Nevertheless it is well established that after refractive errors, chromatic aberrations are the most significant theoretical cause of poor image quality.
He draws mostly on general optical laws, but also looks at mid-wave and long-wave infrared regions, which are particularly useful in correcting chromatic aberrations and athermalization.
