Three Wavefront Sensor Models
There are three different versions available which differ in the type of implemented
microlens array (MLA, see data here Microlens Data ) and its distance to the
CCD camera sensor.
WFS150-5C / WFS10-5C uses a MLA with a chrome mask on it that prevents
light going in between the microlenses directly to the CCD detector. This
increases the image contrast of the detected spotfield and improves the
instrument accuracy, especially in case of strong wavefront deformations. The
wavelength range is not restricted by an AR coating and covers the full
sensitivity range of the Silicon CCD detector 300 - 1100 nm (with largely
reduced sensitivity at the edges). Take into account that such a chrome mask
