Metalens Enters AR Glasses Mass Production: Optics Shift from Refraction to Nanostructures

Shenzhen Metalenz China announced its Metalens optical lens has entered AR glasses mass production, with initial supply to Rokid and Nreal. At just 0.5mm thick, the lens can replace traditional multi-layer refractive optical systems, significantly reducing AR device weight and size.

Shenzhen Metalenz China announced on May 16 that its metasurface-based Metalens optical lens has entered AR glasses mass production. The initial batch supplies AR device makers Rokid and Nreal, with monthly production capacity reaching 100,000 units.

Metalens technology arranges nano-scale optical antenna arrays to focus and image by controlling light wave phase, completely eliminating the need for traditional curved refractive lens structures. Metalenz China CEO Liu Ruopeng said the Metalens is only 0.5mm thick—one-tenth of traditional AR optical modules—weighing less than 1 gram.

Rokid founder and CEO Zhu Mingming said adopting Metalens reduced the new Rokid Max AR glasses to 49 grams, approaching regular sunglasses in wearability. "Optical modules have always been the biggest bottleneck in AR glasses miniaturization. Metasurface technology lets us leap past that hurdle."

However, Metalens currently lags behind traditional solutions in field of view (FOV) and light efficiency. Metalenz China's current Metalens supports a maximum FOV of 52 degrees, compared to Rokid's existing 50-degree products. Achieving the 100+ degree FOV needed for AR/VR fusion still requires further breakthroughs.
