Katana

28⁰ – the industry’s thinnest and lightest waveguide

Ground-breaking, 7grams 1.15mm

Light as a feather, wafer thin

Solves an industry-wide problem

Answering the need for new form factor designs

Katana’s thin, light design unlocks the potential for true mass market commercialisation as it enables a new range of form factor designs for smart glasses and AR headsets. As 5G and connected devices become mainstream, we expect to see an exponential rise in investment in the AR wearables market, especially in the consumer electronics sector.

Prism award-winning
