Abstract
An optic has a freeform optical surface transforming incident light emitted by a spatially extended light source into a constellation of images of the spatially extended light source. The images in the constellation are mixed to form a target illumination pattern having a sharp-edge at least along a portion of a boundary. The images include a focused image, and an edge of the focused image participates in forming the sharp-edged boundary the target illumination pattern.
