Attention
G
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 WFS 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 if you want to use one of the mounting threads M4 or
UNC8-32. Otherwise, this adapter can be omitted.
