EOS 1000 LQS

The Eos 1000 LQS adopts the particular Long Q-Switch pulse length (100ns), specially designed and tested for the cleaning of the gilded bronze frieze of the Gates of Paradise, by Lorenzo Ghiberti, from the Baptistery in Florence. Since its initial application on this masterpiece its use has spread to a wide range of applications that make the EOS 1000 LQS an extremely versatile system for 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 optical fiber and a handpiece with variable focus.
