Abstract: An optical combiner includes a lightguide having an input region, an output region, a relay region intermediate between the input region and the output region, and one or more stress raisers positioned to define a line of weakness in the lightguide. The line of weakness is intermediate between the input region and the output region and extends across the relay region. An in-coupler is disposed at the input region to receive an incident light with a field of view and couple the incident light into the lightguide. An out-coupler is disposed at the output region to couple light out of the lightguide. The optical combiner may be integrated with one or more lenses for use as a combiner lens in a wearable heads-up display.

Abstract: An optical combiner lens includes a lightguide having an input zone at which light enters the lightguide, an output zone from which light exits the lightguide, and a propagation zone between the input zone and the output zone that provides a propagation path for light from the input zone to the output zone. A lens is stacked over the lightguide. A seal engages the lightguide and the lens. The seal is positioned relative to the lightguide such that a portion of the seal is stacked over a portion of the propagation zone. A reflective optical coating is interposed between the portion of the propagation zone and the portion of the seal.

Abstract: A combiner lens includes a first lens, a lightguide, and a second lens. The first lens includes a first lens body and a flange integrally formed with the first lens body. The first lens body and flange define a main cavity. The flange has a first joint surface. The lightguide is disposed at least partially in the main cavity. The second lens includes a second lens body positioned in stack with the lightguide and the first lens body. The second lens has a second joint surface in opposing relation to the first joint surface. The second lens is attached to the first lens by a joint formed between the first joint surface and the second joint surface.

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.
