1. A transmissive color polarization manipulator, comprising:

  • a retarder stack comprising at least three retarder films each having a retardance and an orientation selected such that, when light from an optical source passes through the at least three retarder films, a desired spectral portion of the optical source is substantially polarized with a first polarization and a different spectral portion is substantially polarized with an orthogonal polarization, wherein the retardance and orientation of each of the at least three retarder films is selected such that the optical power for the desired spectral portion of the optical source substantially polarized with a first polarization is substantially maximized for the given number of retarder films.
