Paper Abstract

The nature of surface errors on diamond-turned optics is frequently machine specific. The diamond tool may have a slightly irregular cutting edge. In addition to the obvious tooling grooves associated with the feed rate, the cutting operation may be beset with subtle oscillations or resonances that affect the quality of the surface. Such errors are typically quasiperiodic in nature and will be so treated in this study. Quasi-periodic surface errors will be modeled where the height of the irregularities is assumed to be a small fraction of the incident wavelength. First order perturbation scattering theory will be used to predict the effect of such errors on the performance of optical systems.
