Laser Processing Head PDT-B
Efficient and Simple Precision

Today, lasers are not the cost determining factor in a laser application and a laser system installation. The efficiency of modern diode, fiber and disc lasers has shifted the cost contribution to the accessories and the system integration. The new laser processing head PDT-B follows the laser's exemplary trend by providing the essential seam tracking and auto focus functions using an unmatched cost-effective design.

One of the most important requirements of the laser application is to locate the focus of the laser beam precisely at the defined seam position. The patented technology of the laser processing head PDT-B handles this task in an amazingly simple manner. A tactile sensor which is directly located in front of the laser focus controls the lateral and vertical beam position and therefore guarantees the correct position on the workpiece.
