From profile control to optical finish: Ion beam processing for augmented reality blazed gratings

As AR and VR devices move towards wider adoption, the demand for high-performance waveguide optics has never been greater. At the heart of these systems are diffractive couplers, where even minor variations in grating profile or surface quality can impact optical efficiency. In this whitepaper, discover how Broad Ion Beam processing enables the precise fabrication and polishing of Blazed Surface Relief Gratings (SRGs), delivering the uniformity, accuracy, and ultra-smooth surfaces needed for next-generation waveguide displays.
