MicroSpotMonitor

Measuring focal geometries of finely focused laser beams

The MicroSpotMonitor is the ideal tool for checking, monitoring and approving very finely focused laser beams, such as are used for example in micro-material processing. The MSM automatically measures and analyses the spatial beam distribution all around the focus in various z positions.

Basics

The focused laser beam is a significant determinant of the quality of the manufacturing result. In most laser material processing, it constitutes the actual tool. The task of the MSM is to certify and monitor this tool for laser systems that are used in micro-material processing. Through regular measurements, any changes in beam profile, focal position or beam dimensions, among other things, can be identified and logged. The results not only assist failure analysis but also the optimization of a process in microprocessing. The various possibilities for using the MSM provide operators with a wide variety of problem-solving approaches for their applications.

In the field

The laser parameters can be simply and reproducibly documented in process development. The commissioning and acceptance inspection of laser systems can be carried out quickly and with uniform quality. Aging processes in optical components, which lead to a change in beam parameters can be recognized in a timely manner. Hence it is possible to plan maintenance work in a targeted way. The parts to be processed are guaranteed to be of uniform quality. Where the equipment breaks down, the source of the failure can be localized easily, reducing outage times dramatically.
