One of the most important parameters of laser material processing is the beam power within the process zone.
Due to absorption processes in the beam guidance and the focussing optics, the beam power is reduced.
Practical experience has shown that dirt and deterioration of optical components cause a growing power dissipation within the beam path from time to time. Furthermore, the machining result can be affected negatively.
Due to the power measurement in the process zone the user gets information about the beam power at the workpiece. To avoid a reduction of the machining quality, the observation of power dissipation should be done over a longer period of time as well as a punctual accomplishment of maintenance. This can be done by a regular repetition of the power measurement.
The EC-PowerMonitor not only measures the beam power in the process zone, but also possesses an integrated selftest-function.
Thus, the functional capability and the accuracy of the measuring device can be checked any time.
