树脂透镜和树脂透镜的成型方法
摘要：
本发明提供一种树脂透镜和树脂透镜的形成方法。本发明中，用同一镶块来制造光学功能面和其周围的安装用基准面，可以防止它们之间产生误差。本发明的树脂透镜(1)具备：具有光学功能的光学功能部(2)和以帽檐状形成于其周围的凸缘部(3)。凸缘部(3)的一个面上设置有作为确定位置固定时的基准的基准面(33)。成形时，形成有基准面(33)侧的面通过主要形成光学功能部(2)的镶块(72)和主要形成凸缘部(3)的托座来成形。凸缘部(3)的基准面(33)和作为光学功能部(2)的基准面(33)侧的面的光学功能面(22)由同一镶块(72)成形，比凸缘(3)的基准面(33)更靠外周侧的面由托座成形。
摘要（英）：

A resin lens (1) includes an optical functional section (2) that has an optical function, and a flange section (3) that is formed around the optical functional section. A reference face (33) is used as reference during positioning and fixing, and is formed on one face of the flange section (3). The face on which the reference face (33) is formed is molded by an insert (72) that mainly forms the optical functional section (2) and a holder that mainly forms the flange section (3), during molding. The reference face (33) of the flange section (3) and an optical functional face (22) that is the face of the optical functional section (2) facing the reference face (33) are molded by the insert, and a face of the flange section that is closer to the outer periphery than the reference face (33) of the flange section (3) is molded by the holder.
