Datasheet OpticsQualityMonitor

OpticsQualityMonitor
The Principle
The OpticsQualityMonitor enables the control of absorption
characteristics of optics in the supplier‘s, processor‘s anduser‘s quality assurance. This does not only ensure that theoptics were manufactured within the specification but also
they meet the requirements when in use. The early detectionof missproduction or incorrect handling in the manufacturing
chain ensures that optics provide the highest performance.
The OpticsQualityMonitor compares the absorption of atranslucent optical element, e.g. from a processing head (lensor flat optics), with the absorption of a reference optic (sametype: material or refraction index, diameter, radii of curvature
and anti-­reflective coating). The temperature increase of theoptics‘ surface is measured, which results from the laser
power absorbed in the optics.

For productivity reasons, the beam powers used in lasermaterial processing are getting higher and higher. This
leads to an increasing thermal impact on the optics
used in the processing heads, resulting for example
in a power-dependent focus shift. The influence of theabsorption properties and the degree of contamination of
the individual elements is becoming increasingly important. This makes quality assurance even more importantfor manufacturers of optics and processing heads.
