The Programmable Focusing Optics PFO is a scanner optics for welding and drilling.

Using two mirrors, the laser beam can be placed at any predefined position within the process field or space, or it can be guided over any contour. Spot welds and seams can thus be welded without moving the workpiece or the focusing optics.

The PFO is available for both pulsed and cw solid-state lasers. Different focal lengths ranging from 90 to 900* mm² enable different processing field sizes.

Using a special control unit, processing can be done "on the fly" in order to minimize positioning times due to overlap of robot and scanner movement.

Depending on the focal length, working areas from
56 x 56 to 406 x 630 mm² can be achieved. The Z-stroke of the PFO 3D of up to ± 220 mm results in a threedimensional working space.
