Visible broadband, wide-angle,thin-film multilayer polarizing beam splitter.

A method is described for the design of a thin-film all-dielectric polarizing beam splitter in which the transmittances for p- and s-polarized light are greater than 0.96 and less than 0.03, respectively, throughout the spectral region extending from 0.40 to 0.70 µm, and for an angular field of 12° measured in air.
