Abstract

The correction of higher order chromatic aberrations in high performance wide spectral band optical systems is the main barrier to achieving improved performance. These higher order chromatic aberrations appear in the form of longitudinal secondary spectrum, transverse secondary spectrum and chromatic variations of the monochromatic aberrations. The origins of some of the chromatic variation aberrations are discussed and some analysis methods for these aberrations are reviewed, with some suggestions for simple extensions to the methods that can be used for their calculation.
