Hi,

totally unsuited for measuring a large number of patches.
Well, now you've got me wondering whether a flatbed scanner could be
repurposed with a few modifications.
Just thinking out loud, suppose the lamp were masked such that only a
small aperture were illuminated, and prismatic element of some kind were
arranged such that the reflected image were split, with the resulting
spectrum being cast across the CCD. With the right software and
calibration, this would provide instant strip-reading capability.
Optics is *definitely* not my strong point, though - does this sound
even remotely feasible?
All the best,
