When closing the application, all settings and data will be saved automatically. These most re-

4.7 Closed Loop Control
To flatten a beam wavefront, Thorlabs deformable mirrors can be run with a feedback control
via a signal from a wavefront sensor. Such a setup, involving light being directed to both the
wavefront sensor and the deformable mirror with feedback from the wavefront sensor through
the Thorlabs Deformable Mirror software is described in the
operation manual for the DMP40 .
Please be aware that the pupil diameter of the DMH40 is larger than the diamter of the DMH40:
14 mm versus 10 mm respectively. Therefore, we recommend to use either the Thorlabs
Wavefront Sensors WFS30 or WFS40, as they have a larger aperture as well, or to apply ap-
propriate corrective optics. Please contact Thorlabs in case of questions.
