11. Emissivity table
The emissivity are values determined by the material of object, profile of its surface, surface
roughness, oxidization, measuring temperature, measuring wavelength and other factors.
They are represented by the thermal radiation ratio " ε" when a black body furnace at the same
temperature is measured in the same wavelength band.
The emissivity " ε" is generally known by a value at the wavelength of 0.65µm when an opticalpyrometer is used. The emissivity changes according to the above factors even if the same material isused. Please use the following table as a reference.
