ABSTRACT:
A polarization pattern assembly produces a polarization pattern. In an embodiment, a polarization pattern assembly includes a frame that supports a polarization pane in a central region of the frame. The polarization pane changes the polarization direction of light incident upon the polarization pane. Different polarization patterns in a pupil of a polarized illuminator can be generated.
