The scan systems of the power SCAN series enable positioning multiple kilowatts of laser power onto a workpiece in just a few milliseconds. In combination with a vario SCAN, the laser beam can be dynamically focused within working volumes, thus allowing non-flat workpieces to be processed.

Apertures from 33 mm up to 70 mm allow small spot sizes and therefore high power densities even with large working distances. The XY mirrors and the vario SCAN´s optics are air cooled, while the scanners, electronics and vario SCAN are water cooled. This ensures reliable operation with excellent long-term stability – even under challenging environmental conditions and with high laser powers. Each axis of the power SCAN 50, 50i, 70 and 70i is individually implemented as a sealed submodule – a calibrated and tuned unit containing a galvanometer scanner with a mirror and the scanner’s drive electronics. Thus, rapid replacement of individual axes is en-sured. Located in a separate sealed base module, the modularly-designed main electronics provide functions such as a digital interface and a power management system with comprehensive monitoring functions.

The power SCAN i-series of scan systems employs the same i DRIVE ® electronic concept used in the success-proven intelli SCAN ®. This brings improved dynamics and advanced querying possibilities. The series includes both the power SCAN 50i and power SCAN 70i.

Typical Applications:

• Laser processing of materials

• Rapid manufacturing

• 3D applications

• Processing-on-the-fly
