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.
- Constructed with one ED glass element that provides effective compensation for axial chromatic aberration
There are 13 elements in 10 groups, including two FLD and 2 SLD elements to minimize chromatic aberration and internal reflections.
Proprietary optics correct for chromatic aberration and reduce roll-off to as little as 6dB at 1.2mm imaging depth.
A Lens Aberration Correction function minimises resolution loss and coloured edging caused mainly by optical chromatic aberration. Quick EZ Focus Assist provides distinct enhancement to the viewfinder signal, enabling the camera operator to make critical focus adjustments.
In addition, the Vision Intelligence Platform includes advanced vision processing capabilities necessary for IoT segments such as staggered HDR to prevent the "ghost" effect in high-dynamic range video, advanced electronic image stabilization, de-warp, de-noise, chromatic aberration correction, and motion compensated temporal filters in hardware.
The team overcame the problem of chromatic aberration by using titanium dioxide nanofins arranged onto the flat lens surfaces to make every wavelength of light to focus at the same time.
Moreover, they can be used in applications where a wideband response is needed due to the fact that these designs have a reduced chromatic aberration of the FL.
Natural light, as a mixture of different monochromatic lights with different wavelengths, may contribute to a backward displacement of the retina toward the eye's image plane, causing longitudinal chromatic aberration (LCA) [33].
There are also three strategically located ED (Extra-low Dispersion) glass elements that work in combination with the aspherical lenses' elements to minimise chromatic aberration and ensure the ultimate resolution is captured.
