What is it that defines a "Lab Grade" instrument, like a colorimeter, as far
as acuracy is concerned? I read on one site that the UDT SLS9400
Tri-stimulus colorimeter is (or was) the first handheld colorimeter to
provide "lab-grade" accuracy and precision.
Is it a function of how well the instrument replicates the 1931 2 degree
Standard Observer sensitivity? And does that translate into a plus or minus
chromaticity accuracy like +- 0.00015, for instance? And do companies go
about characterizing the degree to how well a particular set of filters
makes an instrument adhere well to the 1931 2 degree Standard Observer
curves: with shining the light off a monochromator directly at the
instrument and observing its response at every wavelengths in the visible?
