Chinese Scientists Achieve Breakthrough in AR Glasses Technology with Ultra-Thin Silicon Carbide Lens
Hangzhou, China – Chinese scientists have achieved a significant breakthrough in augmented reality (AR) glasses technology, developing a novel silicon carbide lens that is incredibly thin and lightweight, paving the way for more comfortable and immersive AR experiences.
The groundbreakingtechnology was unveiled by Professor Qiu Min, a renowned optics expert and vice president of Westlake University, along with his team at Mude Micro-Nano (Hangzhou) TechnologyCo., Ltd., a company incubated by Westlake University’s Future Industry Research Center. The new AR glasses, featuring the innovative silicon carbide lens, were showcased to the public for the first time, marking a global first in ultra-thin, rainbow-free silicon carbide AR diffractive waveguide technology.
The silicon carbide AR lens, weighing a mere 2.7 grams per piece, boasts an astonishingly thin profile of just 0.55 millimeters, making iteven thinner than a pair of sunglasses. This remarkable feat is attributed to the utilization of silicon carbide’s exceptionally high refractive index, enabling the creation of a single-layer waveguide that delivers full-color display, unlike traditional multi-layered high-refractive index glass lenses.
This innovation not only significantly reduces the weight ofthe lens but also allows for a compact design through the implementation of ultra-thin encapsulation technology. The result is an AR glasses experience that feels virtually weightless, ensuring maximum comfort for the wearer.
When users wear these glasses, it’s as if they are stepping into a whole new world, remarked Professor Qiu. The glasses seamlessly blend virtual imagery with the real environment, creating a clear and expansive virtual display.
The single-layer silicon carbide waveguide theoretically supports a wide 80-degree field of view for full-color imaging, surpassing the maximum 40-degree field of view achievable with traditional high-refractive indexglass lenses. This wider field of view enhances the immersive experience, allowing users to interact with virtual content in a more natural and expansive manner.
The elimination of the rainbow effect, a common issue in conventional AR glasses, is another significant achievement. This effect, caused by light scattering through multiple layers of lenses, can bedistracting and detract from the overall visual experience. The single-layer design of the silicon carbide lens effectively eliminates this problem, resulting in a clearer and more visually pleasing experience.
The development of this revolutionary AR glasses technology holds immense potential for various applications, including entertainment, education, healthcare, and industrial manufacturing. Its lightweight andcomfortable design, coupled with its advanced optical capabilities, promises to unlock new possibilities in the world of augmented reality.
As the technology continues to evolve, we can expect to see even more innovative applications emerge, further blurring the lines between the physical and digital worlds. The future of AR glasses is bright, and the breakthroughs achievedby Chinese scientists are poised to play a pivotal role in shaping this exciting new era.
