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.

EOS 1000 LQS

Since its initial application on this masterpiece its use spread to a wide range of applications that make the EOS 1000 LQS an extremely versatile system for the restorers thanks, in part, to its small size and light weight. The EOS 1000 LQS is suitable for highly accurate cleaning of metal and gilded surfaces, frescoes and painted surfaces, wood, valuable stone artifacts. The laser beam is delivered through a 3 m (optional 10 m) optical fiber and a handpiece with variable focus.


  • Light, handy and versatile system
  • Ideal for the use on accurate interventions
  • Efficient on different kind of materials (stones, wall paintings, metals, wood)
