Abstract: A near-eye optical element includes one or more infrared light sources and an optical structure. The one or more infrared light sources emit infrared beams. The optical structure includes an optically transparent material disposed over the emission aperture(s) of the infrared light source(s). The optical structure includes one or more facets that diverge the infrared beams.

Abstract: A near-eye optical element includes one or more light sources and an optical structure. The one or more light sources emit beams. The optical structure includes an optically transparent material disposed over emission aperture(s) of the light source(s). The optical structure includes one or more facets that diverge or provide a tilt angle to the beams.
