Paper Abstract

In ISO 10110-5 the rotational symmetric surface irregularity of an optical surface is determined form a set of rotational symmetric Zernike polynomials. For a large variety of aspheric optical surfaces which are manufactured by means of CNC-controlled machines this method leads to inadequate results. CNC-controlled fabrication methods often cause ring-shaped deviations described precisely by calculating the integrals over circles concentric to the axis of rotation. The final result is called 'average radial profile' and shows the cross section over the typical ring- shaped deformations.
