Laser cleaning systems and set-ups
A series of laser cleaning systems are available at IESL-FORTH laboratories.
Laser Cleaning
Surface cleaning, based on laser ablation, is particularly effective for the controlled and selective removal of altered over-layers and unwanted accumulations in a variety of CH substrates (i.e. stonework, easel paintings, icons as well as glass and metal objects).
