Technology
Enabling mass manufacturable optical AI display eyewear
Curved convex lithography — advanced fabrication of 3D microstructures on curved optical surfaces, engineered from the start for industrial production.
Curved convex lithography
Advanced fabrication of 3D microstructures on curved optical surfaces
Conventional lithography assumes a flat wafer. Eyewear lenses are anything but flat — which is why AR optics have stayed in the laboratory. Our platform writes directly onto the curved surface, then carries that structure through to a production mould.
Maskless direct-write lithography
Digital patterning at high resolution, with no mask set to amortise — so geometry changes cost design time, not tooling budget.
Patterning on curved surfaces
The core difficulty in AR optics. We write 3D microstructures directly onto convex and concave optical surfaces, not just flat wafers.
Precision master moulds
Structures are transferred into master moulds that feed conventional injection moulding lines.
Volume injection moulding
PMMA lenses come off standard equipment at standard cost — with the optical function already inside them.
Why now
The market is ready. The assembly line is not.
AI display eyewear is forecast to grow at 24.8% CAGR through 2031. The constraint is not demand or design — it is the manufacturing bottleneck sitting between them.
Optical components
What we fabricate
Four component families, each produced on the same platform and designed to be combined.
Miniaturised precision
Micro-optics
Advanced micro-optics give exquisite control over light paths, making them essential for innovative optical designs.
