About BenarioXR
BenarioXR is a development and manufacturing company from Neu-Isenburg that makes the production of advanced AR/XR optics industrially scalable. At its core is Curved Convex Lithography: a maskless direct-write lithography process that patterns 3D microstructures directly onto curved optical surfaces and transfers them into precision master moulds. From these moulds, PMMA lenses with integrated optical functions are produced by injection moulding, including semi-finished lenses for rimless glasses. Further components include micro-lithographically fabricated micro-optics, optical waveguides and lightguides, embedded photonic structures, a piezoelectric laser beam scanning module (2 × 2 × 4 mm) and SoC computing modules. The team of physicists, optical engineers and manufacturing specialists collaborates with research institutes and manufacturers in Europe and Israel, serving customers in Germany, the EU, Israel and the USA.

Materials & Processes
PMMA (polymethyl methacrylate)
Material for injection-moulded optical lenses and micro-optical components with optical functionality integrated into the part.
Curved Convex Lithography
Maskless direct-write lithography for 3D microstructures on convex and concave optical surfaces.
Maskless nano/micro fabrication
Digital high-resolution patterning without a mask set, enabling geometry changes without tooling costs.
Injection moulding of optical components
Volume production of PMMA lenses on standard machines with integrated optical functionality.
Metallisation
Finishing step of the semi-finished lens from the master mould through to the optically functional component.
Piezoelectric laser beam scanning
Ultra-low-power projection module with a mirror under 0.01 mm in a 2 × 2 × 4 mm form factor.
