Parameter
What does it show?
Position Z [mm]
Shows the actual Z position of the translation stage in mm.
Beam Diameter
X' [µm]Beam
Diameter Y' [µm]
In case of 4-sigma beam widths this panel shows the
ISO11146 compliant 4-sigma beam diameter in the
transformed coordinate system (not lab system) for the actual
Z position.
In case of ellipse clip level beam widths the shown value
equals the min. or max. value of the ellipse.
Azimuthal Angle
[deg]
In case of 4-sigma beam widths the azimuthal angle is the
absolute azimuthal angle obtained by the 4-sigma beam
widhts. The calculation follows the ISO11146-1 standard.
Note that the rotation range is not identical with the
Orientation used for the ellipse. Rotation angle range:
In case of ellipse clip level beam width the azimuthal angle
shows a difference angle to a reference angle. Latter is
calculated out of ten frames at the beginning of each beam
quality measurement.
