摘要 |
<p>Platelike first transparent members (321) and platelike second transparent members (322) are prepared. Each first transparent member has substantially parallel first and second surfaces (film forming surfaces). A polarization splitting film (331) is formed on the first film forming surface. A reflecting film (332) is formed on the second film forming surface. The films are not formed on the surfaces of the second transparent members (322). A plurality of the first transparent members (321) and a plurality of the second transparent members (322) are adhered alternately. A block is cut from the so-adhered transparent members at a prescribed angle to the surfaces and the cut surfaces thereof are polished to obtain a polarization beam splitter array (320). <IMAGE></p> |
