Doesn't your adaptive mode help with the spectrophotometer (or
'spectroradiometer')? Or can the adaptive mode only help to a certain
extend? I understand that colorimeters  with matched filters can be
better because their S:N ratio is quite high compared to what each
pixel (covering a given wavelength band) on the CCD of a
spectrophotometer receives...
