What Is Chromatic Aberration?

When imaging with white light, in addition to five monochromatic aberrations for each monochromatic light, dispersion due to different refractive indices of different colored light will cause different colored light to have different propagation light paths, thus showing The aberrations caused by the differences in the optical paths of different colored lights are called chromatic aberrations (referred to as chromatic aberrations). Chromatic aberration is classified into position chromatic aberration and magnification chromatic aberration due to different properties.

Although optical systems have a series of aberrations, they cannot always be completely corrected and eliminated. However, because the human eye and all other light energy receivers also have certain sensitivity defects, as long as the values of various aberrations are less than an allowable limit, the human eye and other light receivers still do not perceive or reflect the imperfections of their imaging. . Such an optical system is considered to be ideal in a practical sense.
