Abstract

A system includes a spatial light modulator comprising a first substrate, a second substrate, and a liquid crystal layer between the first substrate and the second substrate. The spatial light modulator is characterized by a first retardation and a first phase retardation and has a first slow axis for light propagation. A voltage source is configured to apply a drive voltage to the spatial light modulator and the first retardation of the spatial light modulator is a function of the drive voltage. A retarder is positioned external to the spatial light modulator and is characterized by a second retardation and a second phase retardation. The retarder includes a second slow axis for light propagation. The second retardation has a value such that all illumination wavelengths in a set of illumination wavelengths are above or below a phase retardation value of 0.25. The set of illumination wavelengths includes at least on illumination wavelength in each of at least three different color spectrums.
