NOTE
Do not change the content of these reference files, they would become unusable!
In case only an old file name with unspecified SN and MLA name saved by older
program versions < 2.0 can be found you will be asked how to proceed.
Only click 'Yes' to rename this old file if you are sure that it was generated using the
same WFS instrument and MLA name.
Wavefront Unit and Wavelength
Define the desired wavefront unit using this control switch.
You can select either the absolute unit microns (µm) or relate the wavefront
deformations to the operating wavelength yielding the unit waves. In the latter case
you are required to input the operating wavelength in nm.
Switch to 'waves' unit and then input the operating wavelength of your light source.
The accepted wavelength range is 300 to 1100 nm and corresponds to the
wavelength range of models WFS150-5C and WFS10-5C.
Cancel Average Wavefront Tilt
In practice, the direction of the input beam is not perfectly perpendicular aligned to
the sensor area. The measured wavefront is thereby mainly determined by tip and tilt
and the interesting but small wavefront deformations are not seen in the wavefront
panel. Since wavefront tip and tilt is often less interesting, this option allows you to
cancel the average tip and tilt contribution to be canceled prior to wavefront and
Zernike calculation.
