Abstract: A molding material is heated and pressed plural times when molded is an optical element having a radius of curvature smaller than a radius of a sphere having the same volume as the optical element. When such an optical element is molded, a closed space is formed between a molding material and a transfer surface of a mold in a state where the molding material is placed thereon. Thus, an appearance defect such as a recess is easily generated on the molded optical element. However, since the molding material is molded plural times, it is possible to place the molding materials on the transfer surfaces of the molds after a size of the closed space is adjusted so as not to generate the appearance defect prior to each heating/pressing process. Thereby, it is possible to suppress generation of an appearance defect in the molded optical element.

Abstract translation: 当模制成具有小于具有与光学元件相同体积的球体的半径的曲率半径的光学元件时，模制材料被加热和压制多次。 当这种光学元件被模制时，在模制材料被放置在其上的状态下，在模制材料和模具的转移表面之间形成封闭的空间。 因此，在模制的光学元件上容易产生诸如凹陷的外观缺陷。 然而，由于模塑材料被多次模制，所以可以在将模制材料调整到封闭空间的尺寸之后将模制材料放置在模具的转印表面上，以便在每个加热/压制过程之前不产生外观缺陷 。 由此，可以抑制模制的光学元件中的外观缺陷的产生。
