Abstract: Systems, devices, and methods for light guide based wearable heads-up displays (“WHUD”) are described. Display uniformity may be improved via incoupler double bounce uniformity or eyebox mapping. Grating cosmetic effects may be reduced. FOV may be enhanced by multiple EPEs. Bandwidth may be increased by laser wavelength offsets. The couplers may be a single contiguous photopolymer.

Abstract: An optical combiner lens includes a lens and a lightguide with a gap defined between the lens and the lightguide. Spacers are disposed in the gap to maintain the gap at a set height. A method of making the optical combiner lens and a wearable heads-up display including the optical combiner lens are disclosed.
