A process for the preparation of a transmissive birefringence optical element acting as well as a transmissive birefringence acting optical element

摘要

A process for the preparation of a transmissive birefringence acting optical element (101; 201) with a predetermined orientation of the at least one the birefringence described below, the optical axis (103) with the following process steps:a) producing a transmissive optical roh - element consisting of the optical material, the voltage double refractive index end properties;b) acting on at least two separate web-like areas of action (109, 110; 209, 210) of the optical roh - element, between which a birefringence is generated, during a predetermined period of time in such a way that a continued external action, without continuous change in the internal stress distribution of the optical material is produced.
