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.
Both sensor types are available with three different types of microlens arrays.
As a special feature the WFS Wavefront Sensor series is equipped with an
interchangeable microlens array mounted into a precision patent pending magnetic
holder. The exchange of the microlens arrays allows economic switching to different
