Abstract
An optical combiner lens for a wearable heads-up display includes a first lens, a second lens, and a lightguide disposed between the first lens and the second lens to form a stack. A first medium gap is defined within the stack and between the first lens and the lightguide, and a second medium gap is defined within the stack and between the lightguide and the second lens. An in-coupler is positioned to receive light into the lightguide. An out-coupler is positioned to output light from the lightguide.
