Chromatic aberration is a type of image defect due to the fact that different wavelengths of light have different refractive indices. In almost all sources I read so far, this type of optical aberration is discussed only with respect to lenses.
The following text is from this webpage:
For many years, chromatic abberation was a sufficiently serious problem for lenses that scientists tried to find ways of reducing the number of lenses in scientific instruments, or even eliminating them all together. For instance, Isaac Newton developed a type of telescope, now called the Newtonian telescope, which uses a mirror instead of a lens to collect light.
The above statement hints that chromatic aberration is not present in mirrors due to their extensive usage in place of lenses long time ago. But, is the chromatic aberration eliminated completely or partially due to the use of mirrors? I'm having this doubt since, refraction takes place even in mirrors in addition to reflection, from the glass layer (present before the silvered surface). Or in other words, can mirrors give rise to chromatic aberration?
