Abstract
A method for manufacturing an optical element out of glass comprises placing a blank made of glass on an annular contact face of a supporting body having a hollow cross section. The blank is heated on the supporting body in a cavity of a protective cap that is arranged in a furnace cavity, such that a temperature gradient is established in the blank in such a way that the blank is cooler inside than on an outside region. The blank is press molded to form the optical element.
