Abstract

An accuracy analysis of FAUST and WAGNER (two fabrication techniques for rotary symmetric aspherical optical surfaces) is presented. Since within FAUST and WAGNER the three functioning elements of a curve generator are separated they can be used to balance each other. A procedure will be described enabling the determination of the influences of tool shape errors and misalignments on the generated surface shape, demonstrating that there is an advantageous error propagation factor between tool shape and generated surface shape. For the generation of a specific surface, this procedure can be used to determine the optimum fabrication process.
