The reflective focusing optics RFO is a high-powered optic for welding applications at very high laser powers of up to 16 kW and even higher. Because of the mirror principle, the RFO is distinctive for minimal thermal focus shift – with high laser powers, this is the key for reliable welding results. It also guarantees that you get reproducible, high-quality welding results even with high laser outputs. The reflective focusing optic RFO is also optionally available with the proven monitoring functions of the CFO. This makes the RFO even more robust.
