BeamMap2 Collimate Multiplane Slit-Scanning Beam Profiler
BeamMap2 represents a completely different approach to real-time beam profiling. It extends the measurement capabilities of Beam'R2 to multiple locations along the beam path. This real-time scanning-slit system uses pairs of XY slits in multiple Z planes on a rotating disk to simultaneously measure four beam profiles at four different Z positions. BeamMap2's unique design is particularly advantageous for real-time measurement of focal position, M², beam divergence, and pointing. Compared with the standard BeamMap2, BeamMap2 Collimate is specially designed with plane spacing significantly increased by 5 mm for well-collimated beams.
