Optimize your lasers with additional functions

TRUMPF offers you sophisticated solutions that make your production safer, more efficient, and more transparent. Whether monitoring, data storage or interfaces - discover the smart functions to configure our fiber lasers according to your requirements.

BrightLine Weld - Precise weld seams, less spatter

With the patented BrightLine Weld 2-in-1 beam shaping system, the laser power can be flexibly distributed between the core and the ring. The ring jet enlarges and stabilizes the opening of the keyhole so that process gases can escape more easily. This enables low-spatter welding even at high speeds.
The advantage: Less rework, clean weld seams and stable process control - with full control over the power distribution.

Focusing optics

The focusing optics (BEOs) focus the laser beam on the workpiece. The focal point of the lens is the processing point on the workpiece. Depending on the aspect ratio, they apply the full beam quality of the laser for precise applications or work with an increased working distance for processes with a wider diameter or expected spatter formation. As the processing point is fixed, the BEOs must be moved along an axis or the workpiece is passed under the optics. Thanks to the modular design, the optics can be optimally configured for the machining process. Various functions such as Crossjet, protective glass monitoring and process sensors such as VisionLine are available. Bi- and multifocal beam output is also possible in order to process a workpiece at several points.
