Augmented Reality Device Solutions – Oxford Instruments Plasma Technology
Augmented Reality, or AR, is a technology that allows users to visualise and interact with computer-generated objects layered on top of real-world environments.
AR, as well as mixed reality (MR), requires an optical combiner which allows the eye to see the real-world whilst projecting a virtual image. AR has a number of applications in B2B market with applications such as manufacturing, training, security and surgical procedures.
Applications for consumers are just as numerous with use cases such as gaming, shopping or navigation. AR is on-trend to be highly-popular in the near future. A number of products have already demonstrated the potential for AR, amongst which established product like Hololens from Microsoft and Magic Leap One by Magic Leap.
For optimum optical performance, waveguide-based combiners must be manufactured with tight tolerances. When manufacturing the master mould for surface-relief gratings in light couplers and excellent control of the CD, the angle and the depth of the gratings is required. This can be achieved through mask dry etching and angled grating etching processes.
Our advanced plasma processing solutions – achieved with ICP Etching, RIE and Ion Beam Etching – can handle wafers up to 200mm in size for high-volume production of AR devices.
Our Ionfab system for IBE has been configured for optimum uniformity on 200mm wafer size. Our proprietary ion beam technology and patent filed grid design allow us to produce standard 45° gratings with excellent precision. Our processing capability covers various materials such as Si and SiO2.
