On September 26, according to the "West Lake Science and Technology" official micro message, by West Lake University and its incubation enterprise Mu De Wei Na led the research of the "extreme thin and thin silicon carbide AR diffraction optical waveguide" scientific and technological achievements in September 24, the world's first silicon carbide AR glasses lens scene debut. It looks the same as everyday sunglasses, but compared with traditional AR glasses, it is thinner and lighter, with a single weight of only 2.7 grams and a thickness of only 0.55 mm.
According to reports, in the traditional AR diffraction optical waveguide glasses, the heat accumulation generated by the projection optical machine and the sensing and computing unit will make the device enter the overheating protection, so it can only display a small area of the screen. Different from the traditional mirror leg heat dissipation method, this silicon carbide AR glasses use the nature of the material itself, through special design, innovatively use the lens for heat dissipation, greatly improving the heat dissipation efficiency.
In addition, in order to achieve a full-color display, traditional AR glasses usually need to use multiple layers of high-refractive index glass to conduct light, which leads to thick and uncomfortable lenses. The silicon carbide AR glasses only need a waveguide to present a full-color picture with a large field of view.
It's worth mentioning that Meta launched its first true AR glasses, Orion, on September 25. Orion AR glasses feature a stylish black frame design, weigh just 98 grams, and feature silicon carbide lenses and a Micro LED micro-display.
TrendForce Consulting analysis, Orion AR glasses optical design using silicon carbide material diffraction optical waveguide, combined with JBD's three-slice full-color LEDoS technology, can achieve up to 70 degrees of field of view (FOV).
