Manufacturing Wafer-Level Optics Using UV Adhesives and Polymers

Micro-optics and nanostructures are key technologies for the latest optoelectronic components in smartphones, smart glasses and vehicles. Some examples used in consumer electronics include microlenses in time-of-flight or ambient light sensors, diffractive optical elements (DOE) for structured light generation, as well as surface relief gratings with nanometer precision in diffractive waveguides that enable new applications like 3D sensing and augmented reality glasses.
