SCHOTT: High-Index Glass Wafers for Augmented Reality Applications
According to SCHOTT, RealView wafers give AR device manufacturers the first opportunity to expand the FOV almost to the limit of human peripheral vision.
SCHOTT RealView™ optical glass wafers for augmented reality (AR) applications reportedly double the total internal reflection angle compared to conventional glass wafers, enabling a larger field of view (FOV) in AR devices. According to SCHOTT, RealView wafers give AR device manufacturers the first opportunity to expand the FOV almost to the limit of human peripheral vision. SCHOTT produces raw glass in its melting facilities in Germany, and the wafer manufacturing and optical coating takes place in China, where SCHOTT recently announced a joint venture investment with Zhejiang Crystal-Optech.
“Augmented reality should still look like reality,” said Rüdiger Sprengard, Ph.D., vice president and head of Augmented Reality, Advanced Optics at SCHOTT. “To raise the bar and meet the requirements of this rapidly expanding market, manufacturers need superior optical wafers with qualities a full order of magnitude greater than what has previously appeared on the market—a challenge SCHOTT scientists and engineers have accepted in the spirit of pushing the limits of process technology and metrology.”
According to SCHOTT, RealView glass wafers are available with tailored refractive index and excellent light guiding properties. The wafers are reportedly 10 times flatter, measured as total thickness variation (TTV), than industry-standard glass wafers.
