Device description
4.1
Device types
There are two types of MSM+ HighBrilliance:
•
MSM+ HB10
•
MSM+ HB20
Fig. 4.1:
MSM+ HB10
Fig. 4.2:
MSM+ HB20
The main distinguishing feature between the two devices is the absorber, which is dimensioned for different
beam powers. The MSM+ HB10 is designed for a maximum beam power of 10 kW. The MSM+ HB20 is
designed for a maximum power of 20 kW and is therefore equipped with a larger absorber.
Due to the special absorber design of the MSM + HB20, the possible maximum travel in z-direction is limi-
ted: it is 120 mm for the 10 kW type and 40 mm for the 20 kW type (not with the fiber bridge installed!).
The x- and y-axes of the 20 kW type are fixed. The device cannot be moved in x- or y-direction.

Functional description
The MSM+ HB is used to analyze the focused laser beam in the range from 20 μm to 1000 μm. For this
purpose, the device records the power density distribution in the area around the focus in form of a caustic.
A caustic comprises several measurement planes (according to ISO 11146-1 at least 10). A measurement
plane maps the true power density distribution at an associated z coordinate along the optical axis of the
laser beam.
