The Eos Combo, the result of a collaboration between El.En. and the Consiglio Nazionale delle Ricerche (CNR), combines two temporal regimes in one system.

By pressing a key you can move from the Short Free Running (SFR) mode, with a pulse duration ranging from 30 to 110 microseconds, to the Long Q-Switch (LQS) regime, with 100ns pulses. This versatility allows the treatment of a wide variety of materials, such as stones, metals, wall paintings, wood, ceramics.

The system was tested under the most difficult field conditions and, thanks to its sealed laser head, demonstrates high reliability.

The Eos Combo, employing new optical fibers, combines manageability and performance, guaranteeing the conservator the optimization of costs and results.
