To point out the danger of evaluating lenses on the basis of color-blind polychromatic OTFs, it has been shown that lenses with completely different chromatic aberrations can have the same polychromatic OTF. An analytical technique-chromatic aberration matching-is proposed that will ascertain the chromatic aberrations that are different and yet give the same polychromatic OTF for a specified spectral combination of the light source and the detector. A typical numerical example is given which supports the theory and the discussion.
