Welcome to the FOC-2023 conference !

The Frontiers of Optical Coatings (FOC) conference is a top-level conference about optical coatings held in Asia and one of the world's largest and highest-level academic conferences. The FOC conference series aims to promote research in scientific and industrial developments of optical coating and foster scientific exchange between researchers, practitioners, scientists, students, and engineers across the entirety of optical coating and its affiliated disciplines. FOC-2023 is the fifth FOC conference on optical coatings. Like previous FOC conferences, FOC-2023 will feature paper presentations, special tracks, invited speakers, workshops, tutorials (short courses), poster sessions, senior member presentations, and exhibit programs. The conference scope includes the following topics:
