Abstract

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.
