Abstract

The invention relates to a method for producing an optical element from glass, wherein a portion of glass or a glass blank is blank-pressed, in particular on both sides, to form the optical element, wherein the optical element is then placed on a transport element and passes through a cooling path with the transport element, without the optical surface of the optical element being touched.
