The measurements were …

WebChromatic Aberrations • Variation of lens aberrations as a function of wavelength • Chromatic change of focus: W 020 • Chromatic change of magnification W 111 ... Material dispersion can be a desirable or undesirable effect in optical applications. The dispersion of light by glass prisms is used to construct spectrometers and spectroradiometers. However, in lenses, dispersion causes chromatic aberration, an undesired effect that may degrade images in microscopes, telescopes, and photographic objectives.

WebWhat is chromatic aberration? Chromatic aberration, also known as color fringing, is a color distortion that creates an outline of unwanted color along the edges of objects in a photograph. Often, it appears along metallic surfaces or where there’s a high contrast between light and dark objects, such as a black wall in front of a bright blue sky. WebTrue.
