3.6 Emissivity
When measurements are required at wavelengths other than the one used for factory radiometric
calibration, or if the calibration was done thermometrically (see above), the graph below provides
emissivity vs. wavelength for this model. Integrating over the wavelength region of interest will
provide the average emissivity for your measurement. If the blackbody was calibrated
radiometrically, the apparent emissivity at 8-14um was normalized to 1.0. If the blackbody was
calibrated thermometrically, the target emissivity vs. wavelength can be read directly from the
graph.
