I haven't looked at the specs for a while (since the first hotcat test), but the Optris calculation of the temperature isn't a simple function of the temperature. The way they describe their calculation, it seems to be the sum of a number of calculations with different powers of ... something. The only way to find out which direction it goes with emissivity would be to point the optris at a known temperature source, enter a range of emissivities and see how the predicted temperature varies. The MFMP folks should be able to do that during their callibration.
