摘要	Provided is an optical element manufacturing method by which optical elements, such as a beam shaping element having a molded side surface, are highly efficiently and accurately manufactured by pressure-molding a molten glass drop. After supplying a lower molding die with the molten glass drop of a prescribed volume at a temperature higher than that of the molding die, the molten glass drop is pressure-molded by the molding die, and a free surface solidified without being in contact with the molding die is formed between a molded upper surface and the molded side surface. The volume of the molten glass drop to be supplied is 0.8 times or more but not more than 0.97 times the volume of a space configured by an extended molded upper surface, an extended molded side surface and the molded lower surface when the molded upper surface and the molded side surface are extended.
其他摘要	本发明提供一种光学元件制造方法，通过对该熔融玻璃滴进行加压成形，能够高效且准确地制造光学元件，例如具有成型侧面的光束整形元件。在低于模塑模具的温度下向下模塑模具供给规定体积的熔融玻璃滴后，通过模塑模具对熔融玻璃滴进行加压模塑，并且自由表面固化而不与模具接触。模塑模具形成在模塑的上表面和模塑的侧表面之间。待供应的熔融玻璃滴的体积是由延伸的模制上表面，延伸的模制侧表面和模制的下表面构成的空间的体积的0.8倍或更多但不大于0.97倍。模塑的侧表面延伸。
主权项	A method for manufacturing an optical element having an upper molded-surface, a lower molded-surface, and a side molded-surface by pressure-molding a molten glass drop using a molding die having an upper die for molding the upper molded-surface, a lower molding die for molding the lower molded-surface, and a side molding die for molding the side molding surface, the method comprising the steps of: supplying the lower molding die with the molten glass drop of a predetermined volume and a temperature higher than a temperature of the molding die; pressure-molding, after the molten glass is supplied to the lower molding die, the molten glass with the molding die so as to form a free surface, between the upper molded-surface and the side molded-surface, to be solidified while being apart from the molding die, wherein the predetermined volume is 0.8 times or more and 0.97 times or less a volume of a space defined by an extended upper molded-surface made by extrapolating the upper molded-surface, an extended side molded-surface made by extrapolating the side molded-surface, and the lower molded-surface.
