Abstract
An automated ion-beam processing system for shaping optical surfaces 5 0-500 mm in diameter has been created, with automatic maintenance of t he processing regimes, precise positioning of the beam on the surface, and high sputtering rate of the material by the ion beam. A software package has been developed for automated process planning for fabricat ing high-accuracy aspherical (including nonaxisymmetric) surfaces and for finishing (retouching) the surface shapes of optical components, w ith a shape accuracy of lambda/40-lambda/60 rms.
