BeamMonitor BM+ with LDS 2.98

Revision 01/2018 EN
Resolution
Possible settings:
•
32 x 32 up to 1024 x 1024
Generally, 128 pixels per line and a total of 128 lines is sufficient. The resolution in y-direction stipulates the
number of lines and the resolution in x-direction the number of scanning points per line. The measuring time
gets longer if the number of measuring tracks increase. In case of 128 x 128 pixels the minimum distance
between two measurements with regard to the time is 8 to 9 seconds.
The time for the data transfer depends on the amount of data and on the interface. The amount of data
increases with a higher resolution. The performance of the computer also has an influence on the data
transfer time.
Detector
When the device is connected with the PC, the software will set the correct detector automatically. A manual
selection is not possible.
Manual z-axis
Please activate this option if the z-position of the measuring plane is not run by the internal z-axis.
In this case, please enter the z-values for each plane manually in the menu

single measurement
. The software then carries out a caustic analysis on the basis of the determined
beam radii and the z-values.
The beam propagation ratio can also be determined this way, using the measured data of the unfocused
beam in different distances from the beam source.

Twisted tip
Not relevant for the BeamMonitor BM+, this function must not be activated.
Radius correction
Activate the radius correction when measuring rectangular or linear laser beams. This option compensates
the curvature of the scanning tracks.
