Hum...well, my scanner can simply stop down, or open up the lense aperture
if I want.  It\ufffds a cold cathode tube, not fluorescent...but same difference.
So, I have a many stop range I can use...but have found absolutely no need
to.  The other thing that most any scanner can do is MTF over the flat
field, and simply stopped down enough so you don\ufffdt have any depth of field
problems...

Why can not the exact same results be achieved by adjusting the exposure
time?  All you are doing is moving the data on the curve up or down, by
adjusting either exposure/aperture/light source.
