A dual TIR prism has an input prism, a wedge prism, an output prism, and a reflective polarizer. The dual TIR prism is configured to receive an optical beam at an entrance surface, to pass the first polarization direction of the received optical beam from a second exit surface, and to output the second polarization direction of the received optical beam from a first exit surface of the input prism. |
