Abstract
An optical element is disclosed. The optical element includes a single, transparent, rotationally-symmetric lens with a batwing shaped cross-section, extending angularly away from a longitudinal axis. The lens also includes a variety of curved, straight, specular and optionally diffuse portions on its longitudinal and transverse faces, all of which cause a variety of internal and external reflections, refractions, and optionally scattering.
