的残留歪を大幅に減少できる。 As a result, the residual distortion imparted to the plastic lens can be reduced compared to continuous oscillation. The reason for this is thought to be that even after the first vibration ends, separation of the interface between the jig and the plastic lens continues, albeit for a short time. And the second
This vibration is applied to further progress the peeling, and repeating this process completes the peeling. In such a method, the unique peeling behavior of the jig and the plastic lens is not ignored, but rather the unique peeling behavior is actively utilized, so that the microscopic residual strain mainly exerted on the plastic lens can be significantly reduced.
