103Operating the Beam Profiler
For aligning a beam the entire camera sensor should be used. The Region of
Interest (ROI) can be changed to Full Size in the Device Settings. For more
information see chapter Device Settings .
Lens alignment
For a M2 measurement a focussing element like a lens is necessary. If the laser
beam is set up parallel to the translation stage axes adding a lens into the beam
pathway is quite easy.
When inserting a lens the Beam Profiler should rather be at the end of the stage than
at the front. If the beam was centered before the lens was added the lens has to be
positioned in X and Y direction so that the beam in centered again. In doing so it is
crucial to avoid any tilt of the lens.
During the lens alignment please make sure, that the camera never enters
saturation. Therefore observe during movement the status bar. The closer the
BC106 moves to the focus (beam waist), the higher beam intensity and the shorter
exposure time becomes. When the BC106 is located close to the beam waist,
select the correct ND filter from the filter wheel in order to avoid saturation.
When the beam is still centered at all stage position the lens is well-aligned into the
optical path.
