If all criteria are fulfilled, the measuring results have a high reliability. The absolute accuracy can not be stated
from the standard deviation from the fits as all the systematic measuring errors as well as the accuracy of the
calibration are additionally taken into account when it comes to the absolute error.
24.4.7 Raw beam (menu
Presentation > Raw-beam)
Not relevant for HP-MSM-HB.
24.4.8 Symmetry check (menu Presentation > SymmetryCheck )
This display menu checks the rotational symmetry of the power density distribution of a laser beam. It can,
for instance in connection with the monitoring operation (
Measurement > Single > Monitor ), be used for
the alignment of laser resonators.
In the following, the figures Fig. 24.20 on page 132 and Fig. 24.21 on page 133 show two examples for
the possible results of a symmetry check at an elliptic beam and a circular beam.
Fig. 24.20: Dialogue window (menu Presentation > Isometry ) power density distribution of an elliptic beam
The power density distribution of an elliptical beam as shown in Fig. 24.21 on page 133 together with the
Symmetry check
comes to the following results.
