In the race to make augmented reality feel natural rather than novel, the bottleneck has rarely been software. It has been optics, and this is where Vitrealab is placing its bet.
In a recent development, Vitrealab has closed an oversubscribed $11 million Series A round, led by LIFTT Italian Venture Capital and LIFTT EuroInvest, with backing from Constructor Capital, aws Gründungsfonds, Gateway Ventures, PhotonVentures, xista Science Ventures, Moveon Technologies and Hermann Hauser Investment.
The funding will be used to accelerate the development and industrialisation of Vitrealab’s Quantum Light Chip (QLC). Vitrealab plans to strengthen collaborations with customers and partners, demonstrate next-generation light-engine architectures, and continue building the technical foundation required to bring AR displays into everyday use.
When AR’s biggest problem is light, not code
Augmented reality has reached an inflexion point. Displays are expected to be brighter, lighter, more power-efficient and discreet enough to disappear into everyday eyewear. Traditional optical architectures struggle to meet all those demands at once. Vitrealab’s answer lies in photonics, specifically, photonic integrated circuits designed to tame and shape laser light with extreme precision.
Its technology targets laser–LCoS light engines, reducing optical losses and system complexity while preserving beam quality and polarisation. The result is a rare combination: higher brightness and a wider field of view, delivered in lightweight smart-glasses form factors. It is a structural rethink of how AR light engines are built.
From quantum roots to industrial scale
Vitrealab was founded in 2018 by Dr. Chiara Greganti and Dr. Jonas Zeuner, both former researchers at the University of Vienna, with early support from Anton Zeilinger’s Quantum Group.
At the core is its Quantum Light Chip, developed using proprietary direct laser writing and in-house fabrication tools. By controlling design and manufacturing under one roof, Vitrealab can move rapidly from prototype to volume production while maintaining precision and reproducibility. This vertical integration allows for customisation without sacrificing consistency, an advantage when working with Tier-1 OEMs planning mass-market AR devices.
The new funding will accelerate industrialisation, deepen customer collaborations, and showcase next-generation light-engine architectures. If AR is to shift from niche gadget to everyday companion, Vitrealab is positioning itself as one of the quiet enablers making that transition possible, by solving the hardest problem first.
“The successful closing of our Series A is a strong validation of our technology and our vision for scalable AR display systems,” said Dr. Jonas Zeuner, CTO of Vitrealab. “This funding allows us to move from advanced prototypes to industrial-grade solutions, while continuing to push the boundaries of what is possible with photonic integrated circuits in display applications.”
“Augmented Reality has reached a point where the market is ready but the hardware is not, and in particular the display,” said Marco Cravetto, Business Analyst at LIFTT. “Vitrealab addresses this challenge at its core with a proprietary laser-based technology that combines performance, industrial scalability and a strong European IP foundation.”
