Walt just seeing this on holiday- i just continued your AI query:
Do you actually have data a waveguide is not needed: links/ anything?
Anything that says we don't need a waveguide, also addressing Meta saying they are working with it, chief scientist saying LBS is the ultimate but needs the waveguide? Would appreciate what you are thinking?
Yes, for a modern wearable form factor, MicroVision’s laser-scanning technology **requires a waveguide** (or a similar optical combiner) to bridge the gap between the micro-projector and the wearer’s eye. 
While MicroVision’s core [MEMS technology](https://microvision.com/about/our-story) creates the image by scanning lasers, that light must still be "guided" into the user's field of view to allow for a "see-through" experience. 
Why a Waveguide is Necessary for AR Glasses
* **Transparent Overlay:** A waveguide acts as a clear lens that allows you to see the real world while simultaneously reflecting the scanned laser beams from the temple-mounted projector into your eye.
* **Form Factor:** Without a waveguide, the projector would have to be placed directly in front of the eye (blocking vision) or use bulky [prism-based optics](https://www.shanghai-optics.com/about-us/resources/technical-articles/optical-waveguides-in-ar-glasses-an-overview/) like those in early Google Glass.
* **Pupil Expansion:** Laser-scanning engines produce a very narrow beam. Waveguides use "exit pupil expansion" (EPE) to enlarge the "eyebox," ensuring you can still see the image even if the glasses shift slightly on your face. 
Recent Developments (2025–2026)
* **Industry Collaboration:** In late 2025, a new industry working group was formed to optimize [waveguides specifically for laser displays](https://www.reddit.com/r/augmentedreality/comments/1pamhwn/laser_display_for_ar_has_a_new_working_group/), as most existing waveguides were originally tuned for MicroLEDs.
* **Next-Gen Materials:** As of 2026, companies like [Lumus](https://www.prnewswire.com/news-releases/lumus-unveils-next-gen-waveguides-for-ar-glasses-at-ces-2026-including-its-first-geometric-waveguide-to-exceed-70-field-of-view-302653598.html) and [Vuzix](https://www.vuzix.com/blogs/vuzix-blog/waveguide-technology-a-critical-component-for-ar) are releasing ultra-thin waveguides that can be integrated into standard prescription frames, which are designed to pair with compact LBS (Laser Beam Scanning) engines like those developed by MicroVision.
