Optical Characterization of High Refractive Index Glass Wafers for Augmented Reality Wearables

Abstract

Refractive index and optical thickness homogeneities of 99.979% and 99.984% were determined by using wafer-size metrologies. SiO2 & Nb2O5 based low loss anti-reflective coatings in the visible were realized for augmented reality wearables.
