ABSTRACT:
Disclosed is a polarization beam splitter and a method of producing the same, in which the polarization beam splitter has superior polarization separation efficiency and has small angle dependence. A transparent base material having a polarization separation film, comprising a dielectric multilayered film, is cemented at the cemented surface of the beam splitter, to provide an array-like plane type polarization beam splitter, wherein an incidence angle θg of light upon the polarization separation film is selected to satisfy a relation θg>45 deg.
