WebAxial chromatic aberration (ACA) occurs everywhere in the field of view, and is pretty much the same everywhere. The fact that the refractive index (nλ) of glass is different for different wavelengths causes this. The result is that a simple lens (e.g. a magnifying glass) has a different focal length for each wavelength of light as shown in figure 1.1a below.
