M310-HT Manual Appendix A: Calibration & Emissivity 20
Emissivity (for M310, M315, M316 series blackbodies)
Accuracy at all wavelengths
When measurements are required at wavelengths other than the one used for factory
radiometric calibration 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
8-14 µm was normalized to 1.0. The target emissivity vs. wavelength can be read directly from
the graph. Again, you would have to normalize the mean emissivity between 8 and 14 µm to
1.0, then correct for other wavelength regions. The next two pages have examples that do this
normalization for you.
When calibrating infrared sensors at wavelengths other than 8-14 µm region, the graph below
displays the target effective emissivity vs. wavelength after factory radiance calibration is
performed.
