There is a lens inside the giant A1 scan head which is on a motorized
translation mount.  My system is heavily hacked (it's what I do) so I have
manual control over it.  Normally the A1 software is configured to jog the
lens around somewhat.  You can use it to adjust the spot size at the back
aperture of the lens.  You'll have to ask Nikon what the software normally
does with that lens control in the unhacked version.
