Emissivity Coefficients of Some Common Materials

November 25, 2008

We’ve been trying to preach to the inexperienced about Spectral Emissivity vs (just plain) emissivity.
The former is the subject used in Thermal Infrared Radiation Thermometry (Pyrometry, to some) and users of Thermal Infrared Imagers (Thermographic or Thermography Cameras) while the latter is the domain of radiation heat transfer considerations (except of course when spectral [...]

Raytek’s Emissivity Table for Metals

August 20, 2007

The Raytek North America website contains a table of spectral emissivity for metals with values at 1.0 micrometers (micron). 1.6 microns and the 8-14 micron waveband. Many values are blank or labelled “nr” for “Not Recommended”. Many others cover relatively wide spans of values, varying as much as a factor of 4. The metals [...]
