ABSTRACT:
A disclosed polarization beam splitter is effective when light to undergo polarization-splitting has an incidence angle that falls in a range of 54 degrees through 66 degrees. The polarization beam splitter includes, between two transparent substrates, an adhesive layer configured to adhere to a first transparent substrate of the two transparent substrates, two or more types of dielectric multilayer films having different design basis wavelengths, and a single-layer dielectric film. The dielectric multilayer films and the single-layer dielectric film form a polarization split film, which performs a polarization split function with respect to light that is substantially in the visible wavelength region.
