What is a Polarization Directed Lens?

A Polarization Directed Lens is a thin (0.45mm) flat window with a complex photo-aligned liquid crystal polymer (LCP) film deposited on the surface. By varying the geometrical phase shift spatially, the LCP achieves near perfect diffraction efficiency of the holographically recorded lens wavefront. Essentially, a Polarization Directed lens is a thin film equivalent of a geometric optic with very little volume, yielding significant reductions in weight and thickness.
