away from the surface.

Since targets that are less reflective have higher Emissivity, the rough surface and the cavity, illustrated
in

, represent increasingly higher emissivity values—even though they are made from the

same material as the polished surface.

It is best to measure targets with high emissivity values. High reflectance off or transmittance through
the target introduces the possibility of measurement error due to background interference. Avoid
reflections when measuring targets with Emissivity less than about 0.8.

Figure 81: Surface Finish affects Emissivity
