The Optica Design and Fabrication Congress is the premier event for learning about advances in these important areas and highlights the use of modern design tools to reduce cost, augment manufacturability and enhance system performance. Hot topics for this congress include additive manufacturing of optical components; advanced freeform design and fabrication tools for both imaging and non-imaging systems; micro-optics, the use of metasurfaces and other flat optical component techniques in advanced optical systems and how AI and machine learning tools can help in all areas of design, fabrication and testing. The design, fabrication and testing of optical components and optical systems plays an ever-increasing role in our modern society as more applications for optics are developed, especially in the areas of imaging, sensing and illumination systems. PHABULOuS will be presenting the capabilities of the European Value Chain during this meeting.
