5. Which mask or microlens array can be used with FrontSurfer?
(FAQs/Wavefront sensors)

In the reference mode, any mask or microlens array with up to several hundred subapertures over the image sensor area can be used. For the absolute measurement mode, a precision array with complete hexagonal ...

6. What is the precision of FrontSurfer wavefront sensor?
(FAQs/Wavefront sensors)

... In the reference mode, the precision is mainly limited by the image sensornoise and can be improved by averaging over multiple frames and using a microlens array with larger focal distance. In the absolute ...
