LASER CLEANING SYSTEMS
Art. 19811
The activity of El.En SpA in the cultural heritage sector in contact with the research institutions of the scienti c center of Florence, provides technological solutions, constantly validated by the world of conservation.
The small size, convenience and ease-of-use handling make these unique instruments in the  eld of lasers dedicated to the cultural heritage sector. The EOS QS system consists of a ND: YAG long-range laser emitter that emits near infrared energy that is transported by a bundle of  ber optics to the variable focal handpiece. Eos QS System has several advantages:
- little invasive technique, no chemical or abrasive products;
- High degree of control, degradation removal is highly progressive (few microns per pulse);
- High precision, optical  bers used for light transmission allow complex, molded surfaces to be treated.
- Usable on metals, stone walls, wall paintings, wood, ceramics.
- selectivity; the different optical absorption makes the crust ablation more effective than the lighter substrate.
LASE EOS COMBO Art. 19811
The EOS COMBO is a latest generation laser system designed speci cally for the needs of restoration yards. It is possible to go from an operation Short Free Running (pulse duration 30/110μs) to an operation Q-switch (pulse duration 100μs).
LASER EOS QS Art. 19774/QS
The EOS QS is a latest generation laser system designed speci cally for the needs of restoration yards. With operation Short Free Running (pulse duration 30/110μs) is associated operation Q-switch (pulse duration 15μs) with energy to 140mJ.
LASER EOS 1000 LQS Art. 19774/LQS
The EOS QS is a latest generation laser system designed speci cally for the needs of restoration yards. It adopts the particular pulse duration Long Q-switch (pulse duration 100μs) .
