35Operating the Beam Profiler
If the window height is smaller than the full toolbar, the lower symbols are packed into
a context menu which is accessible via a arrow button on the bottom of the toolbar.
Attention
The calculation area must not cut off also lower intensity parts of the beam
profile. This may cause improper calculation results!
The following graph shows an example of chosen ROI and Calculation Area:
Example:
A beam is entering the Beam Profiler once directly and in addition multiple
reflections of it. The ROI is selected to 768 x 768 pixels so that all 3 beams are
visible within the 2D Projection window. But, in order to limit the image interrogation
to the main beam the calculation area was chosen much smaller.
Within this 2D Projection panel, coordinates X and Y are defined as follows:
