Programmable focusing optics

TRUMPF optics for remote processing

The programmable focusing optics from the PFO line are scanner optics for remote welding and cutting. Using state-of-the-art, digitally controlled drives and mirrors, the laser beam can be positioned in any specified position within the processing field or space, or be guided along with any seam geometries. They can thus be welded without moving the workpiece or the focusing optics. Additionally, no shielding/assist gas is required. Increased process reliability and quality are possible with optional intelligent sensor solutions. With the welding on the fly option, robot, laser, and programmable focusing optics are synchronized and positioned precisely in real-time. In the PFO portfolio, you will find a solution for every application, from the low-power to the high-power range.

PFO Product variants

PFO SF

The PFO SF small-field scanner is the compact and versatile scanner with a small work area for quick beam oscillation.
By selecting the right options (objective, collimator and sensor system), the small-field scanner can be flexibly adapted to your application. The PFO SF is suitable for a power range of up to 12 kW. It is not only powerful but also smart with functions such as the protective glass monitoring unit. The optics can also be integrated across the entire TRUMPF range of solutions.

Lasers: TruDisk, TruFiber, TruMicro
Max. laser power: 12 kW (cw)

PFO 20

Thanks to the reworked base body and optimized cooling system of the third generation PFO 20, a laser power of up to 6 kW can be achieved. The digital drive architecture, lightweight construction of the mirror, and new software features such as the Realtime Contour Check and Scanner Precision Control, make the PFO 20 particularly suitable for highly dynamic welding and cleaning applications that require a high level of process stability. The sturdy design of PFO increase resistance to contaminations and back reflections.

Max. laser power: 6 kW (cw)

PFO 33

The third generation of the PFO 33 stands for maximum productivity and can be used for applications with a laser power of up to 12 kW. The lightweight mirrors and the new drive architecture enable maximum dynamics. In addition, optimized mechanical and optical assemblies improve the robustness of the optics against back-reflections. Options such as protective glass monitoring and Condition Monitoring help to maximize the availability of your production.

PFO 3D-2

The PFO 3D-2 programmable focusing optics constitute a 3D scanner which is also based on the pre-objective scanning principle. This allows all points in the scanner’s processing space to be reached with high dynamics and consistent beam quality, at a variable working distance. All NC programs are saved locally in the PFO, which also allows for operation without a PC. Optionally, the 3D scanner is also available with seam tracking with SeamLine Remote triangulation, and the CalibrationLine calibration tool.

Laser: TruDisk
Max. laser power: 8 kW (cw)

I-PFO

The intelligent PFO (I-PFO) recognizes its own position in the work area of the robot and the position and orientation of the processing points. Based on information on the current robot movement, the I-PFO independently starts processing as soon as it is possible in terms of geometry and process technology. Remote processing “on-the-fly” is thereby possible, which greatly reduces both the positioning time of the robot and the cycle times in your production operations.
