Liquid crystal (LC) beam control devices using a dispersion shaped (DS) half wave plate (HWP), with specific physical characteristics, allows the broadened beam to maintain significantly better the color cohesion. Beneficial aspects of using a HWP with an appropriate thickness and birefringence index which makes it inefficient in the blue wavelength spectrum, therefore reducing the blue photon depletion in the center of the broadened beam is described herein. Combinations of an homeotropic LC cell and DS HWP structures for reduced color separation, faster relaxation time and reduced ground state scattering is further described herein.
