After my last article, Meta Orion AR Glasses (Pt. 1 Waveguides), I got to thinking that the only other diffractive grating waveguide I have seen with a 2-D (X-Y) expansion and exit gratings, used in Meta’s Orion, was from Wave Optics (purchased by Snap in May 2021)

The unique look of Wave Optics waveguides is how I easily identified that Snap was using them before it was announced that Snap had bought Wave Optics in 2021 (see Exclusive: Snap Spectacles Appears to Be Using WaveOptics and [an LCOS] a DLP Display).

I then wondered what Magic Leap Two (ML2) did to achieve its 70-degree FOV and uncovered some more interesting information about Meta’s Orion. The more I researched ML2, the more similarities I found with Meta’s Orion. What started as a short observation that Meta Orion’s waveguide appears to share commonality with Snap (Wave Optics) waveguides ballooned up when I discovered/rediscovered the ML2 information.

Included in this article is some “background” information from prior articles to help compare and contrast what has been done before with what Meta’s Orion, Snap/Wave Optics, and Magie Leap Two are doing.
