Abstract

The mastering of an industrial process to economically manufacture high precision aspherics is of utmost importance to obtain high performance infra-red systems, in the 3-5 and 10-13 micrometers ranges. The research and results of such a process is presented. Starting with a close spherical surface, material is being brought by vacuum evaporation. Between the rotating lens and the source, one or several masks of specific shapes determine the aspherical curvature profile. Up to 50 micrometers of material can thus be added to a sphere.
