Has anyone posted a deep dive yet on pinning down which exact waveguide design is being used and which exact projector (based on past papers, M&A activity, key hires, etc.)? I'm surprised Karl Guttag hasn't published anything yet about either Orion or Spectacles 24. https://kguttag.com/ His blog is normally the definitive source for reverse-engineering AR optics systems from public information. Maybe someone posted a deep dive on Reddit or something ?

I'll post links here that could serve as a starting point:

- The microLED display panel vendor is likely to be Plessey: https://www.uploadvr.com/facebook-plessey-microled-deal/

- The waveguides are likely being produced "directly" by a contract manufacturer working under the direction of Meta's in-house team, and reporting appears to confirm that Meta is procuring the raw materials directly: "The silicon carbide waveguides are also proving challenging to procure. The material can deliver a wider field of view than the glass waveguides used in current transparent AR headsets, but it is also incredibly expensive. Further, Ma's report explained that because the material is used in military radars and sensors, the US government imposes strict export controls on it. That means glasses using it will have to be assembled inside the US, significantly raising the production cost, despite most of the manufacturing and components coming from China and Taiwan." https://www.uploadvr.com/meta-ar-glasses-lead-claims-as-mind...

One thing I don't understand is whether the current Orion announcement is actually a new announcement or is re-announcing an already publicized project. This article from 2023 talks about Orion and its 70 deg FOV in the past tense as a line of development which Meta considered but then decided to abandon after Orion in its plans for the 2027 consumer version to be called Artemis: https://www.theverge.com/2023/7/19/23800228/meta-ar-glasses-... "Meta’s Artemis glasses will reportedly use a glass waveguide, a component that allows light to travel through the glasses and into your eyes, potentially limiting its field of view to 50 degrees. According to The Information, Meta had originally planned to use silicon carbide, which allowed for a 70-degree field of view. The downgrade could make it harder for Meta’s consumer-focused glasses to stand out among the competition, as both Microsoft’s second-gen HoloLens and the Magic Leap One sport a 50-degree field of view."

Maybe the hope is that with the Orion test devices, Meta can see whether people care about 70 deg vs 50 deg FOV enough to justify the costs of US-based waveguide manufacturing for the generation after Artemis?

Disclaimer: I worked extensively on Snap Spectacles for a number of years so I'm highly biased, but credit where credit is due: I believe both Meta and Snap have done incredible work in their AR glasses and I am excited to see the competition heating up. I also hope that both company's efforts here can motivate Apple and Google to get in the game instead of sitting around doing more or less nothing really interesting or adventurous while cautiously sitting on piles of cash, while life passes us by and we get closer every day to old age. For heck's sake, either one of those tech giants could privately fund a LITERAL moon base, and they choose not to. Why should we have to live in a boring world? Life is short and I'd rather we get to see some very magical tech soon, in our lifetimes, instead of the tech companies conservatively waiting around for more of Moore's Law to happen first or something. Even Magic Leap, though a colossal failure, pursued a wonderful vision - to create innocent, whimsical literal magic in people's lives - like the world of Harry Potter - in our real world.
