POLARIZATION SEPARATION ELEMENT AND METHOD FOR MANUFACTURING THE SAME, POLARIZED LIGHT BEAM SPLITTER, AND POLARIZATION CONVERSION ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a polarization separation element and a method for manufacturing the polarization separation element that can be made thin compared to the prior arts and can be inexpensively manufactured by an easier manufacturing method compared to the prior arts, and a polarized light beam splitter and a polarization conversion element using the polarization separation element.;SOLUTION: A polarization separation element (1) includes a transparent resin substrate (2), a plurality of prism faces (3) disposed on at least one surface (2a) of the transparent resin substrate (2) as integrated with the transparent resin substrate (2), and a polarization separation film (4) disposed on each prism face (3).;COPYRIGHT: (C)2015,JPO&INPIT
