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 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.
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.
The level of chromatic aberration is also excellent.
Caption: This is chromatic aberration, and it is the most common form associated with large objective lenses.
The complex design features 22 lens elements configured in 16 different groups, including one Super ED (Extra-low Dispersion) and two ED glass elements, all of which are working together to minimise chromatic aberration and ensure the ultimate resolution is captured.
Achieving accurate chromatic aberration reduction and high transmission rates across a broad spectrum, from UV to near IR
Its images are bright, contrasty and sharp from edge to edge, and the chromatic aberration (color fringing) that's the curse of cheap cameras is absent -- either because the iPhone lens is particularly good, or because it's processed out by the software.
This lens contains 13 elements in 11 groups, with 2 aspherical elements and 1 extra-low-dispersion (ED) element to minimize chromatic aberration.
In her newest film, Chromatic Aberration (2014)--commissioned by Tyneside Cinema in Newcastle upon Tyne, UK--Aura Satz explores this nexus through research into film color technologies.
They hold ED (extra-low dispersion) glass to compensate for chromatic aberration, plus dielectric high-reflective multi-layer prism coatings for brighter images in all lighting conditions.
Newly developed WF series objectives with improved chromatic aberration correction ensures bright images without color fringes throughout the entire field of view.
