Optical arrangement for e.g. projection lens, has structure for optimizing arrangement with respect to angle of incident angle-dependent polarization division in phase and amplitude, and another structure compensating change of wave front

摘要

The arrangement (1) has a coating (3) with a correction structure (6) that locally changes optical path length and/or intensity of a light coming through the coating. The structure is designed for realizing local optimization of the arrangement with respect to an angle of incident angle-dependent polarization division in phase and amplitude and transmission change. A wave front of the light coming through the coating is changed. Another correction structure (7) formed on a surface (4) of an element body (2) and compensates change of the wave front caused by the former structure. Independent claims are also included for the following: (1) a method for manufacturing an optical element (2) a method for optimizing an optical imaging system.
