The Principle The FM+ is an opto-mechanically scanning measuring system that scans the laser beam with a special measuring tip. This is equipped with a small hole (typically with a diameter of approximately 20 µm) that lets through a small section of the laser beam. Two reflecting mirrors guide this portion of the laser light to a detector selected and configured depending on the laser power and wavelength. This makes it possible to measure the different laser beam sources and systems solely by selecting the optimal measuring tip and corresponding detector. The high orbital velocity of the rotating...

Enhanced Functionality thanks to the new LaserDiagnosticsSoftware With the new LaserDiagnosticsSoftware (LDS), the FM+ offers considerably more functionality than ever before. It allows for fully automatic, semi-automatic, or manual measurement of the power density distribution, beam position, and beam dimensions. The measurements can be recorded with a high resolution and freely selectable ROI (region of interest). Higher dynamics enable you to determine the beam diameter even when there is a bad signal-to-noise ratio. Other parameters Presentation of typical measuring results of the FM+ within...
