black body
As applied to heat radiation, this term signifies that the surface in question emits radiant energy at each wavelength at the maximum rate possible for the temperature of the surface and, at the same time, absorbs all incident radiation. Only when a surface is a black body can its temperature be measured accurately by means of an optical pyrometer.
