Converting spin angular momentum to orbital angular momentum has been shownto be a practical and efficient method for generating optical beams carryingorbital angular momentum and possessing a space-varying polarized field. Here,we present novel liquid crystal devices for tailoring the wavefront of opticalbeams through the Pancharatnam-Berry phase concept. We demonstrate theversatility of these devices by generating an extensive range of optical beamssuch as beams carrying $\pm200$ units of orbital angular momentum along withBessel, Airy and Ince-Gauss beams. We characterize both the phase and thepolarization properties of the generated beams, confirming our devices'performance.
