In a groundbreaking development for augmented reality (AR) technology, researchers at Westlake University have unveiled the world’s first silicon carbide (SiC) AR glasses. This innovative product was launched by Moldnano, a spin-off company from the university, on September 24, 2024, in Hangzhou, China. The introduction of these glasses comes at a pivotal moment, just days before Meta’s much-anticipated unveiling of their Orion AR glasses.
The SiC AR glasses are notable for their incredibly lightweight and slim design. Each waveguide weighs a mere 2.7 grams and has a thickness of only 0.55 millimeters. This remarkable feat is made possible by the use of silicon carbide, a material known for its ultra-high refractive index, excellent thermal conductivity, and low density. These features collectively contribute to a more streamlined and comfortable user experience, setting a new standard in the AR industry.
Min Qiu, the chief scientist at Moldnano and a chair professor at Westlake University, showcased the glasses, emphasizing their capability to deliver a full-color display using just a single waveguide layer. In contrast, traditional AR glasses typically require multiple layers of high-refractive-index glass, resulting in a bulkier and less user-friendly design.
One of the standout features of the SiC AR glasses is their impressive theoretical field of view (FOV), which reaches up to 80 degrees for a single-layer full-color display. This significantly exceeds the 40-degree limit commonly found in traditional high-refractive-index glass solutions, promising a vastly more immersive experience for users across various applications, from entertainment to professional environments.
Addressing a common issue faced by AR glasses, Moldnano’s researchers have effectively eliminated the “rainbow artifacts” that often distract users. This has been achieved through meticulous design of the waveguide structure, resulting in a clearer and more enjoyable viewing experience.
Heat management has long been a challenge in the realm of AR technology, but Moldnano has introduced an innovative solution that utilizes the lens itself for heat dissipation. This approach allows for prolonged use of the glasses without overheating, marking a significant advancement over traditional cooling methods.
This development is a significant milestone in the field of micro-nano optics and plays a crucial role in enhancing China’s AR industry chain. As competition heats up with Meta’s impending release of the Orion AR glasses, Moldnano’s announcement is poised to further invigorate the rapidly evolving AR hardware market.
Industry experts predict that such technological advancements will expedite the integration of AR into everyday life. Potential applications for these glasses are vast, extending into sectors such as education, healthcare, entertainment, and industrial use. The introduction of SiC AR glasses not only showcases the innovative spirit of Westlake University but also highlights the potential for AR technology to transform various aspects of our daily routines.
