  • Patent number: 9638836
    Abstract: A lens includes a material spanning an area and providing an inside reflective three-dimensional (3D) surface. The reflective 3D surface is defined by a plurality of reflective optical elements including a first reflective optical element and at least a second reflective optical element that each include a sub-element set including a center sub-element (CS) and a plurality of neighboring sub-elements. The plurality of reflective optical elements each have their own non-overlapping optical center axis; and a cylindrically bent spherical surface. The cylindrically bent spherical surface is defined by the neighboring sub-elements in each reflective optical element being located at different 3D points so that the reflective optical elements relative to at least one neighboring reflective optical element provides different values of spherical curvature and different values of cylindrical axis orientation.
