General
Thorlabs wavefront (Shack-Hartmann) sensors consists of a camera with a mounted
in front of the camera sensor microlens array (MLA).
There are 2 types of sensors differing in the type and performance of the camera.
WFS150/300 series, based on a CCD camera (higher resolution, but slower
performance)
WFS10 series, based on a lower resolution CMOS camera enabling
remarkably higher measurement speed at a somewhat reduced measurement
accuracy.
