I think he would need some kind of absolutely radiometrically source.
Spectroradiometers are calibrated using mercury and other lines sources so
that the wavelength scale of the instrument could be tuned or corrected. In
Germany, Jeti uses Optronix lamps to calibrated their specbos
spectroradiometers. A fine instrument indeed ;-)


I was just thinking of something simple as a first step,
which would be to setup some typical spiky source (like a CRT
monitor sample), and measure it with the reference instrument,
then the i1pro in 10nm and then 3.3nm mode. See if there is
and improvement (measured by the delta E to the reference
measurement) in going from 10nm to 3.3nm.
This could be done for a few different display colors.

Something like a Photo Research PR-6XX, PR-7XX,
or Konica-Minolta CS-1000 would be typical reference
instruments for this sort of thing.
