Abstract

A scheme for using as-produced surface irregularity data from asphere production for numerical statistical tolerance analysis is presented with this paper. Interferometric precision measurements are being modeled in Zernike space and then used for monte carlo tolerancing analysis. We show that low Zernike frequencies dominate the image distortion behavior of the irregularities found in the specific asphere production process. Very good agreement between model representation and measured data effect is found.
