Optinvent Optinvent designs and produces geometric/reflective optical waveguides, which are unique due to their construction from monolithic injection molded plastic elements. Their chief use is in augmented reality glasses, but they are also used in avionics applications. The upcoming generation can expand images in 2D. The company also used to produce smart glasses with their waveguides but has pivoted towards being a pure waveguide design house. Optinvent
