Abstract
Faceted optics for use in conjunction with (typically planar) arrangements of discrete light sources (e.g., an array of multiple LED dies) improve or optimize the trade-off between beam divergence and beam non-uniformity, and between non-uniformities resulting from the imaging of the extended light source and artifacts introduced by the optic itself.
