Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to make an incident luminous flux to exit with the directions of polarization made the same by tilting a polarized light separating plane at a specific angle to incident light. SOLUTION: A polarized light converting element is formed out of a polarized light separating plane M11 for separating incident light into mutually straight-going reflected light and transmitted light by a plane of polarization, a reflecting plane M21 for reflecting either of the reflected light and the transmitted light and directing it almost in the same traveling direction of the other light, and a 1/2-wave plate F1 for matching both planes of polarization with each other by varying at least one of the planes of polarization of the reflected light and the transmitted light. In such a composition, the polarized light separating plane M11 is tilted at an angle of 47-53 degrees to the incident light. Incident light La on a glass block G11 is separated into P- and S-polarized light via the polarized light separating plane M11.  The P-wave is transmitted through the polarized light separating plane M11 and made to exit from a light exit surface GE. The S-wave is reflected thereby and further reflected by the reflecting plane M21, and then, it is directed in the same direction of the P-wave. After the S-wave has been made to exit from the glass block G11, the plane of polarization of the S-wave is rotated by 90 degrees, and it becomes P-wave to be made to exit from the light exit surface GE.
