Held every three years, Optica OIC — Optical Interference Coatings Conference, has served for the past four decades as the premier conference on the topic of optical interference coatings. OIC covers all aspects of optical coatings, including fundamental research on coating design theory, materials, deposition methods, characterization technologies and applications in electronic displays, optical communication, high power and ultra-fast lasers, sensing, solar cells, low-emissivity coatings, optical instruments and space. The conference consists of five days of oral and poster presentations. None of the sessions are held in parallel, so attendees can listen to a short presentation on every paper and then choose to visit the posters of greatest interest. Each session starts with invited talks by world-leading experts. The conference also includes: three problem contests that demonstrate the state-of-art capability in the design, manufacturing and measurement of optical coatings short courses that cater to the needs of beginner through advanced levels a four-day technical exhibition by companies to display their latest products a special evening technical presentation
