Know everything about your production parameters in less than 3 seconds with the PRIMES ScanFieldMonitor (SFM). The handheld ScanFieldMonitor features an innovative measuring principle tailored specifically for additive manufacturing processes, and its small glass structure and compact design make it perfect for laser beam diagnostics and process optimization.
A piece of glass with a specific measuring structure is what distinguishes the innovation of the PRIMES ScanFieldMonitor (SFM). A photo diode captures the scattered light while scanning the laser beam over this structure and uses this information for fast laser beam characterization. Not only will it tell you the width of the beam on the measuring plane, but it will also allow you to reconstruct the path, position, and length of the beam and determine its speed of movement.
Complex relations such as pincushion distortion, the merging of overlapping scanning fields, and delays in laser activation and deactivation can be analyzed using special measuring schemes. This can be used to synchronize the laser with its scan unit. Using the 3D machine construction platform to move along the z-axis makes it possible to measure the caustic and determine the evenness of the plane. And ScanFieldMonitor is small enough to be placed just about anywhere over the working area.
