Note: Changing the camera resolution will also change the number of detectable
spots. In case you are working with a 'User Calibrated Reference' a new
User Calibration may be required.
Depending on the selected camera resolution in pixel the resolution of the
Wavefront Sensor, that is the number of the calculated microlens spots is also
defined thereby. The number of microlens spots in x and y direction is as follows:
Camera resolution in pixel Wavefront resolution No. of wavefront
points
320 x 320 9 x 9 81
512 x 512 15 x 15 225
768 x 768 23 x 23 529
1024 x 1024 31 x 31 961
1280 x 1024 39 x 31 1209
The wavefront resolution is by the factor microlens pitch / pixel size lower than the
camera resolution. This means about 32x32 CCD pixels are mapped to one
single microlens.
Image Averages
Averages will reduce measurement noise which can be advantageous in case a
low-level light source has to be analyzed. An average setting higher than 1 will
