Operating Instruction
This section gives a more detailed description for operating the WFS series
Wavefront Sensors.
4.1
Measurement with the Wavefront Sensor
Attention
Do not stick something into the aperture at the Wavefront Sensor front!
You may damage the microlens array because there is no covering glass in
front of it.
Be very careful in handling high power optical beams, especially if they are
focussed!
Avoid skin irradiation and use laser protection glasses the protect your eyes!
Measurement results of the Wavefront Sensor are influenced by the user's setting
such as the pupil size and other setup parameters of the instrument. It is
recommended to study the Shack-Hartmann Functional Principle as well as the
setup options (see Wavefront Sensor Setup Panel ) in order to perform reliable
wavefront measurements.
Mounting options
A mounting adapter (see Mounting Adapter ) is added to the camera housing of
the Wavefront Sensor in order to supply standard threads M4 and UNC8-32 which
are compatible to the palette of Thorlabs' mounts and posts holders. Mount this
adapter plate on the bottom side of the Wavefront Sensor using the 4 screws M3x6
(WFS) and 2x M3x6 + 1x M2x6 (WFS10) if you want to use one of the mounting
threads M4 or UNC8-32. Otherwise, this adapter can be omitted.
The C-Mount threading on the face of the CCD or CMOS camera allows with the
help of an adapter (Thorlabs SM1A9) for the convenient mounting of ND filters, to
help prevent the saturation of CCD pixel, and lens tubes to reduce scattered light
