  The Lynx sees to be an improvement over the other
microscopes shown on their web site based on the
amount of exit pupil magnification.

  The millions of pixels mentioned make it
sound like a disk with lenticles on it (small
individual lenses rather than a squished single
lens that a fresnel lens is).

  I can't quite picture the benefit of rotating
this lenticular disk though. Unless it beams
the exit pupil in one direction at a time and the
rotation makes it scan over a larger volume to
achieve this 64x enlarged exit pupil.
