WebA target’s emissivity, reflectance and thermal conductivity values will be highly dependent on material properties. Most non-metals have emissivity values near 0.9, which means that 90% of the measured radiation comes from radiation emitted by the target. Most polished metals have emissivity values near 0.05 to 0.1.
