Abstract

An illumination optical component for a head mounted device includes an input aperture, an optical substrate, a hot mirror layer, and exit feature voids. The input aperture is configured to accept near-infrared light from a light source. The optical substrate has a refractive index. The hot mirror layer is disposed on the optical substrate. The hot mirror layer is configured to confine the near-infrared light to be recycled within the optical substrate and configured to pass visible light. The exit feature voids are patterned into an eye-side of the hot mirror layer. The exit feature voids are configured to illuminate an eyebox region with near-infrared illumination light.
