METHOD FOR SHAPING AN OPTICAL COMPONENT IN ORDER TO PRODUCE AN ASPHERICAL SURFACE

摘要

The invention relates to a method for shaping an optical component (2) such that said component has an aspherical optical surface. According to the invention: the optical component (100) is heated and mechanical stresses are applied thereto; the heating and the application of the mechanical stresses (200) are stopped; an optical surface (4) of the component is polished to a planar or spherical shape (400); and the delayed resilient deformation of the optical component (500) is relaxed. The present invention is particularly useful in the production of aspherical mirrors having a large size.
