BeamMap2

The BeamMap2 is similar to the Beam’R2 scanning slit laser beam profiler, but also features scanning on multiple planes in beam direction.

Overview

The BeamMap2 allows you to measure the M² factor in real-time. With the unique design of the BeamMap2 profiler scan head, it is also possible to measure the position of the centroid in XY on each plane and the focal position in Z. The multi-plane based slit scanning also enables you to calculate the beam direction and divergence.

The ability to rotate the scan head along the laser beam axis means that measurements of astigmatism and M² in different axis of the beam are possible. An integrated encoder shows the effective angle in the software.
