sahi Glass Co., Ltd. has developed a high-transparency, high-refractive-index glass substrate for use in augmented reality (AR)/mixed reality (MR) glasses.

AR and MR glasses, particularly those that are eyeglass-shaped wearables, are expected to become popular as they virtually augment images or scenes on display. The market for these AR/MR glasses is expected to expand as the next-generation device following smartphones.

For these glasses, Asahi Glass has been developing and proposing glass substrates for semiconductor packages and optical electronic components with a wide range of characteristics. This has led to the development of a high-transparency, high-refractive-index glass substrate ideal for use in AR/MR glasses, which the company has started researching and developing few years ago.

A glass substrate for AR/MR glasses requires high refractive index to extend the viewing angle as well as high transparency to vividly show images. It also requires highly advanced glass processing technology to transmit images with extreme accuracy, for instance by achieving high flatness and smooth surfaces. With its high refractive index and high transparency, this newly developed glass substrate is a product that combines all of these characteristics. Asahi Glass aims to continue expanding this product across a wide range of markets that include not only the AR/MR glasses market, but also the in-vehicle technology market.
