VIENNA, Austria and TØNSBERG, Norway -- April 23, 2026 -- Vitrealab GmbH and
poLight ASA (OSE: PLT) today announced a collaboration to advance laser
illumination architectures for LCoS-based augmented reality (AR) displays,
with a focus on mitigating coherence-related image artifacts while preserving
system efficiency and compactness.
Laser-based illumination offers clear system-level advantages for LCoS based
AR light engines, including high optical efficiency due to intrinsic
polarization, improved etendue utilization, and scalability to high brightness
levels. However, coherence artifacts, manifesting as speckles and fringes,
have remained a primary barrier to adoption in LCoS-based near-eye displays.
In past years, Vitrealab has developed a proprietary technology called Quantum
Light Chip (QLC) to reduce coherence artifacts below visibility in AR light
engines. This novel laser matrix illumination increases efficiency and
brightness at a small form factor.
poLight contributes its TWedge® wobulation technology, a piezo-actuated
transmissive tunable device that dynamically modulates the optical wavefront
and reduces perceived coherence artifacts.
"The TWedge® wobulator from poLight helps us to improve light engine
architectures with its transparent design." said Chiara Greganti, CEO and
Co-Founder of Vitrealab. "poLight's solution simplifies the light path and
increases the efficiency of our Quantum Light Chip compared to our previous
MEMS approach."
"Laser and LCoS represent a powerful combination for AR displays," said Øyvind
Isaksen, CEO of poLight ASA. "By providing low power, ultra compact tunable
optics to Vitrealab's Quantum Light Chip, we are excited to help create a
higher performing, more compact, and more manufacturable AR system. This
collaboration signals progress both for laser-based LCoS engines and TWedge®
technology."
The cooperation will include joint development, prototype demonstrations, and
coordinated commercialization efforts.
