<p>A method and an apparatus for optical-element molding in which a material in a mold can be heated or cooled so as to form a symmetrical temperature distribution according to the shape or optical performance of an optical element to be molded. The method for optical-element molding comprises the steps of heating, press-molding, and cooling through a mold composed of an upper die, a lower die, and a barrel die, wherein in at least any of the heating, press-molding, and cooling steps, a mold pedestal (heat transfer member) having an approximately symmetrical temperature distribution is brought into contact with the mold to heat or cool the mold.</p> |
