Display the Results at a Certain Z Position
After measurement is finished, the calculated beam diameter, the beam centroid positions (X'
and Y'), and the beam ellipticity can be retrieved for a certain Z position from the diagram. To
do this, move the mouse pointer over the measured curves. For better visualization, the curves
can be zoomed by dragging a rectangle:
As soon as the mouse pointer hits a measurement point, its shape changes to . Click this
point. The position and calculated values corresponding to the clicked point will appear in the
Calculations Results of the Selected Point panel:
Note
In contrast to the Results pane, the results shown here are calculated from the measured data
point without a hyperbolic fit. Therefore, the diameter value displayed at the actual waist may
differ from the X' (Y') waist diameters.
