Yes, the imaging electronics is the same as a scanning electron
microscope, the beam scan electronics probably a bit different but
mostly the same ideas (using electrical or magnetic fields to scan the

Yep, I'm guessing this has imaging... it would be pretty hard to focus
to <5nm without some feedback to check edges for!
