CCD and color error of lenses Refractors, Cassegrain, Maksutov and some more are using lenses.
Optical designers try to minimize color errors for human vision.
So at the spectral limits of human vision color error increases, but you can't see it. I have recorded the spectrum of wega with a grating in front of my refractor. The first picture is without any filter. You can see Wega in the middle of the picture and first order spectrum at left and rigth side of wega. The picture is inverted and shows a calculated wavelenght bar.
