Paper Abstract

This paper describes the determination and selection of tolerance values used by a tolerance based weighting program written by the authors. Equations for the amounts of low and medium order wavefront aberration permissible in an optical system are plotted as a series of wavefront and transverse ray aberration curves. This data provides the basis for a determination of individual tolerancing schemes for particular optical designs, based on their performance requirements. The maximum amount of wavefront aberration allowable in an optical system, where the required performance is limited by the maximum spatial frequency required to be passed, is also considered. These permissible wavefront aberrations in terms of reduced spatial frequency are presented as a series of curves for a range of reduced spatial frequencies s. For a tolerance-based weighting scheme it is necessary to assign a set of tolerances to each of the aberration sample sites involved in the merit function in such a way that they can be interpreted by the optimization program. The method presented in this paper is to translate the permissible wavefront aberration curves into transverse ray aberration data. In this form the data becomes accessible to transverse ray aberration based optimization algorithms.
