Graeme, 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... -Rishi On Mon, Jun 20, 2011 at 5:25 PM, Graeme Gill <graeme@xxxxxxxxxxxxx> wrote: > Rishi Sanyal wrote: >> >> Knut, the Spyder 3 is a colorimeter, yes?
