WebOct 13, 2024 · In fact, aberrations in optics are classified into two types i.e., Chromatic Aberration and Monochromatic Aberrations. Chromatic Aberrations The inability of a lens to bring all the rays of different colours to focus in one plane after refraction is called chromatic aberration. Monochromatic Aberrations shannon floyd dpmIn 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.
