The growing need to preserve our cultural heritage is causing a rise in the demand for increasingly accurate cleaning techniques, featuring high selectivity and low impact.


The system is compact and lightweight and the beam delivery through a 1500μm optical fiber allows freedom of movement and ease of use. Thanks to this versatility EOS QS allows the cleaning of stones, metals, wood, gilt objects, frescoes and painted surfaces.


  • system with two temporal regimes: Q-switch and Short Free Running;
  • beam delivery through optical fiber;
  • compact and versatile laser;
