ABSTRACT:
A phase shifting mirror comprising a thin film layer of metal provided on a substrate, and a thin film layer of dielectric material provided on said thin film layer of metal, wherein by utilization of a phase difference between a P-polarization reflected component and an S-polarization reflected component resulting from the reflection on the boundary surface between the layer of metal and the layer of dielectric material and variations in refractive index and film thickness of the dielectric material, a desired phase difference is obtained between the P-polarization reflected component and the S-polarization reflected component.
