97Operating Instruction
Setup the Wavefront Sensor to work using the internal reference. Do the appropriate
setting within the Wavefront Sensor Setup Panel .
Adjust the point source straight in front of the Wavefront Sensor at a distance in the
range 10 cm to 5 m. The Wavefront Sensor will measure the distance and displays it
as Radius of Curvature RoC.
Larger distances are better suited for calibration because the wavefront curvature is
lower and closer to a plane wavefront
Start the calibration procedure using Menu Calibration Spherical
Wavefront or simply click on the appropriate symbol in the toolbar. The following
panel illustrates the required calibration setup.
Click 'Do Calibration' to perform the user calibration.
In case you are currently working with an user reference you will reminded to switch
to the internal reference.
