Optimize Your Laser with Additional Features

TRUMPF offers well-thought-out solutions that make your production more efficient, safer, and more transparent. From monitoring and data storage to interfaces – explore smart features to configure our fiber lasers to meet your needs.

BrightLine Weld – Precise Welds, Less Spatter

With patented 2-in-1 beam forming, BrightLine Weld allows flexible laser power distribution between the fiber core and fiber ring. The fiber ring beam enlarges and stabilizes the keyhole opening, allowing process gases to escape more easily. This enables low-spatter welding even at high speeds.
Your advantage: Less rework, clean weld seams, and stable process control – with full control over power distribution.

To the product group

Focusing Optics

Focusing optics (BEOs) focus the laser beam onto the workpiece. The focal point of the lens determines the exact processing location on the material. Depending on the imaging ratio, they either deliver the laser's full beam quality for high-precision applications or provide an extended working distance for processes requiring a broader beam diameter or where spatter formation is expected. Since the processing point remains fixed, BEOs must either be moved along an axis or the workpiece must be guided beneath the optics. Thanks to their modular design, the optics can be optimally configured for the specific processing task. Various features are available, such as Crossjet, protective glass monitoring, and process sensors like VisionLine. Additionally, bi- and multifocal beam outputs enable processing at multiple points on a workpiece.
