Emissivity
Description
Emissivity of a material is the ability of its surface to emit
thermal radiation. More accurately, it is the ratio of the
energy radiated from a material's surface to that radiated
from a perfect emitter (black body) at the same temperature
and under the same conditions. The emissivity of a surface
depends on the material and on the nature of its surface. For
instance, a polished metal surface has a lower emissivity
than an oxidized metal surface.
Since this thermal imaging camera calculates the surface
temperature of objects by sensing their emitted thermal
radiation it is important to take emissivity into account. A
