title: Polynomial ray aberrations computed in various lens design programs.
abstract: The specific definition for each polynomial ray aberration term computed in six current lens design programs is presented. A comparison between programs was performed that found significant variances in term definitions. Several anomalous term computations are reported. In addition, certain characteristics of the compared programs are contrasted, and a consistent aberration term definition scheme is recommended for adoption by all programs.
