German specialty glassmaker SCHOTT AG introduced on Tuesday SCHOTT RealView, a high-index glass wafer that allows more immersive augmented reality (AR) applications, to the Chinese market.

The new SCHOTT RealView wafers are made from optical glass with a high refractive index of 1.6-2.0, compared to an index of 1.5 typical for the former generation of glass wafers. Following the rules of optics, the total internal reflection angle responsible for the guiding of the image is doubled in SCHOTT RealView™ wafers, correlating to larger field of view, according to the company.

Limited field of view (FOV) in AR devices has always a pain for improving the user experience. SCHOTT claims RealView is greatly expanding the FOV, allowing information to appear nearly everywhere within the limits of human peripheral vision. In addition, the wafer is extra thin at 0.025mm, making it capable of creating a crisp and high contrast image.
