The European Optical Society Annual Meeting, EOSAM, is a major international scientific conference and exhibition covering all aspects of optics and photonics.

The next EOSAM is organized in Tampere, Finland, 24-28 August 2026.

In 2026, we will celebrate 35 years since the creation of the EOS, and 20 years since establishing EOSAM as a platform for experts in the field of optics and photonics, bringing forth new research results, state of the art, and bridging the gap between research, education, and industry. EOSAM is attended annually by around 500 top researchers, key leaders, students, and industry experts.
