Title: LENS MANUFACTURING METHOD AND MOLDING DIE
Abstract:
Provided are a lens manufacturing method and a molding die for which an adjustment operation for astigmatic aberration is easy, and which is capable of suppressing occurrence of comatic aberration accompanying the adjustment. By rotating a fixed-side transfer plane (second transfer plane) (61c) around an axis while fixing a movable side transfer plane (first transfer plane) (51c), astigmatic aberration of a lens (10) is adjusted, and therefore, adjustment operation for the astigmatic aberration is simplified. Furthermore, in adjusting the astigmatic aberration, the operation can be performed while the movable side transfer plane (first transfer plane) (51c) is fixed, and therefore, it is possible to relatively reliably suppress occurrence of comatic aberration accompanying the adjustment.
