Reflective Geometric Waveguides

Reflective geometric waveguides use total internal reflection to guide light from microdisplays into the user's eye for augmented reality glasses, achieving up to 10× better luminance efficiency than competing waveguide technologies. The reflective design uses geometric optical elements to redirect light through the waveguide with minimal loss, resulting in the highest brightness available in AR waveguide displays. This high efficiency enables bright, visible AR content even in well-lit environments, addressing a major limitation of many AR displays.

The waveguides support field of view up to 50 degrees with 2D pupil expansion, which expands the exit pupil in both horizontal and vertical dimensions, allowing users to see the full display even when their eyes move. The technology can directly bond prescription lenses, enabling users with vision correction needs to use AR glasses without additional prescription inserts or adapters. This integration simplifies the user experience and maintains the sleek form factor of AR glasses. The combination of high brightness, wide field of view, and prescription lens integration makes these waveguides well-suited for consumer AR applications requiring excellent visual quality and user comfort.
