I got it now. That is a nice step forward. I wonder why they didn't do this before for individual colorimeters. Actually, why can't they do it now for existing colorimeters? Say you send your colorimter in & they measure the transmission spectrum of each filter? I guess you'd need to then put that in the firmware, etc. which might get complicated? -Rishi On Thu, Jun 23, 2011 at 4:43 PM, Graeme Gill <graeme@xxxxxxxxxxxxx> wrote: > Rishi Sanyal wrote: >> >> cool.
