User Manual
For materials with smooth, clean (unoxidised) surfaces, emissivities are usually in the
range 0.05 to 0.50 and are usually very wavelength dependent, being higher at
shorter wavelengths. The appropriate settings for the

Cameras are given in the following tables. It must be remembered that these are only
guideline figures. They can be substantially increased if the surface is rough or even
slightly oxidised.
The values quoted for oxidised metals assume that the metal is heavily oxidised. Thin
oxide layers will give an emissivity value between this and the value for an unoxidised
surface.
If a more precise emissivity value is needed or more information is required on how to
obtain the emissivity value of a specific material, please contact: us.
