Description
DataRay’s BeamMap2 represents a radically different approach to real-time beam profiling. It extends the Beam'R2’s measurement capabilities by allowing for measurements at multiple locations along the beam’s travel.
This real-time slit scanning system uses XY slit pairs in multiple z planes on a rotating puck to simultaneously measure four beam profiles at four different z locations. The BeamMap2’s unique, patented design is most advantageous for real-time measurement of focus position, M2, beam divergence and pointing.
