ABSTRACT:
The invention provides a method of manufacturing extremely precise glass optical element by thermally deforming optical glass on the optical surf ace of a thermal processing jig coated with chemically stable thin film, followed by the molding of optical glass preform having free surf ace on one side and transcribed surface from the optical surface of the thermal processing jig by means of a press mold which thermally presses the optical glass preform.
