Past research on all-dielectric nonpolarizing beam splitters is reviewed. It is shown that, for a 50-nm spectral region, it is possible to design and manufacture a two-material nonpolarizing plate beam splitter for use at an angle of 45° (with a measured rms reflectance of 0.50 ∓ 0.01 for both <i>s</i>- and <i>p</i>-polarized incident light).
