Abstract:
An optical element molding method comprising pressing a heated optical material to mold an optical element from the optical material, the optical element having an asymmetrical optically functional surface that is asymmetrical along at least one radial direction extending from a center of the optically functional surface, the method includingbringing a center part of a transfer surface of a molding die, the transfer surface having a form, and a center part of a surface of a heated optical material into contact with each other, and thereafter, bringing a periphery of the center part of the heated optical material into contact with the transfer surface, thereby transferring the form of the transfer surface to the heated optical material and forming an optical element with an asymmetrical optically functional surface that is asymmetrical along at least one radial direction extending from the center of the optically functional surface.
