Dear Kees,
in addition to the references suggested by J. Pawley, the article
1. Entwistle, A. and M. Noble, Optimizing the performance of
confocal point scanning laser microscopes over the full field of view.
Journal of Microscopy, 1994. 175(3): p. 238-51.
might also be of help to your friend.
Cheers,
