Patents

The Ondax technology portfolio includes exclusive patents licensed from the California Institute of Technology, acquired and licensed patents, and patents generated at Ondax. It also extends to proprietary manufacturing and testing equipment and processes resulting from a multi-year, multi-million-dollar investment in a high-volume manufacturing infrastructure that enables us to deliver the highest volume, performance, quality, consistency, and traceability.

Multiple proprietary processes are used in the fabrication and testing of Ondax Volume Holographic Gratings (VHGs), in order to ensure superior quality, reproducible performance, and competitive pricing.

Many of these are covered by US Patents, including but not limited to:
