Polarization Directed Flat Lenses are flat lenses formed with polymerized liquid crystal thin-films that create a focal length that is dependent on polarization state. These unique lenses will have either a positive or negative focal length depending on the phase of the input polarization. With right handed circularly polarized light, the lenses will produce one focal length, while left handed circularly polarized light will present a focal length with the opposite sign. Unpolarized light will produce a positive and negative focal length at the same time. Both output waves are circularly polarized and orthogonal to each other. These Polarization Directed Flat Lenses are approximately 0.45mm thick, effectively simulating an ideal thin lens and are free from spherical aberration.
