I see your point for lenses but how would that happen with mirrors?

Yeah, you are correct. The mirrors are not affected by the wavelength, though they are affected by the non-zero angular size of the Sun.

There are some non-linear effects that _are_ dependent on the wavelength, but not important to matter here.
