LACONA “Lasers in the Conservation of Artworks”  – XIII Conference September 12-16 2022 , Florence

September 12-16 2022 , Florence

LACONA “Lasers in the Conservation of Artworks is the International Conference on advances in photonic techniques for diagnostics and conservation-restoration of cultural heritage.
Since 1995, LACONA has gathered together researchers, conservators, and restorers from public institutions and private enterprises for discussing about novel approaches in non-invasive material characterization, conservation treatments, and monitoring based on photon sources and sensors.

The topics of the Conference focus on innovation in dedicated spectroscopic, imaging, and laser treatment systems and on their optimized application over the whole range of the conservation themes of tangible heritage.
