  skos:definition "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 materials decreases with increasing wavelength. Since the focal length of a lens depends on the refractive index, this variation in refractive index affects focusing. Chromatic aberration manifests itself as \"fringes\" of color along boundaries that separate dark and bright parts of the image. (Wikipedia, The Free Encyclopedia, <a href=\"https://en.wikipedia.org/wiki/Chromatic_aberration\" target=\"_blank\">https://en.wikipedia.org/wiki/Chromatic_aberration</a>)"@en, "Une aberration chromatique est une aberration optique qui produit différentes mises au point en fonction de la longueur d'onde. On observe alors une image floue et aux contours irisés. Elle résulte de la décomposition de la lumière blanche en plusieurs bandes de couleurs.
