A multi-region lighting system for flat illumination includes one or more light sources and an optic. The optic comprises a first region characterized by a first refractive-index feature and a second region characterized by a second refractive-index feature. The second region comprises a ridge structure. The first and second refractive-index features and the ridge structure are operative to produce a composite light distribution from the one or more light sources.
