The European Optical Society Annual Meeting, or EOSAM for short, is an international conference that covers a wide range of topics in optics and photonic technologies in numerous topical meetings and sessions. This year it took place from September 11 to 15 in Dijon (France) and was attended by over 500 participants from research and industry.

The consideration of so-called subsurface damage (SSD) in the processing of hard-brittle materials is becoming increasingly important in optical manufacturing. Samson Frank from the EAH Jena demonstrated a non-destructive way of measuring SSD in a USP laser process based on optical coherence tomography.
