HoloWedge™

Superefficient near-eye display,
ready for any consumer-grade eyewear.

The key components of HoloWedge architecture

Our proprietary VPH design and manufacturing capability is built to scale with 15+ years optics experience, an in-house pilot line, and tier-one manufacturer partnerships.

The volume phase hologram (VPH) film

HoloWedge uses a proprietary holographic display architecture in a thin polymer film embedded in the lens.

The combiner architecture

A microprojector couples light into a lightguide, where it is redirected to the VPH and the image is built in front of the user's eye.

HoloWedge makes mass-market AI eyewear possible

Today's waveguides lose most of the display light before it ever reaches the eye. Not for lack of engineering, but because their optical architecture caps what's physically possible. HoloWedge is a new, transformative paradigm.

01

High-performance optical architecture for AI and AR eyewear

The finished HoloWedge architecture is a curved, transparent polymer layer. It's easily embedded in any consumer lens, from lightweight AI eyewear to high-performance immersive AR.

02

Undetectable, superefficient always-on display

HoloWedge delivers 50-70% of the light to the eye, compared to 3-8% for typical diffractive waveguides. That efficiency translates directly into what users feel: all-day battery life, a wider field of view, no forward light leak revealing the display to others.

Because so little light needs to be generated to begin with, the projector produces far less heat, removing the need for bulky thermal management and letting the whole module shrink down to fit inside standard consumer-grade lenses.

Why AlphaLum VPH?

Traditional SRG-based waveguides

  • Low optical efficiency (a few %)
  • Visible forward light leakage ("eye glow")
  • FoV-constrained by material index, forcing reliance on exotic materials for high FoV
  • Compromised see-through quality due to diffraction artifacts
  • Flat waveguides require additional curved optics to meet visual performance standards
  • Reliance on exotic materials introduces complex, cost-intensive manufacturing limiting scalability

AlphaLum VPH

  • 10× higher optical efficiency
  • Extremely low forward light leakage
  • Up to 90° field of view
  • Highly transparent and unobstructed see-through quality
  • Sleek wearable design
  • Scalable polymer-based manufacturing
