Table of Emissivities in Three Popular Spectral Regions

May 9, 2009

The Table of Emissivity on the INFRAPOINT Messtechnik GmbH website (Click here to visit) has summary data for a wide variety of materials broken down into three distinct spectral regions for the wavelength regions where the majority of infrared radiation thermometers and Infrared Thermal Imaging cameras operate.
First and second are tables that deal with the [...]

ET10 Reflectometer Measures Emissivity

March 21, 2008

San Diego CA, USA –Surface Optics’ ET10 measures emissivity values in two most commonly used spectral regions, 3 to 5 and 8 to 12 microns.
Its main application is to produce emissivity values for the infrared cameras.
Advanced IR cameras require the input of an emissivity value for accurate temperature calculations. The emissivity values obtained from tables [...]

IR Emission Spectroscopy of Molten Salts and Other Liquids Using Thick Samples as Reference
J. Hvistendahl, E. Rytter, and H. A. Øye
Applied Spectroscopy, Vol. 37, Issue 2, pp. 182-187 (1983)
Abstract
“The IR emittance of liquids relative to a blackbody is dependent on the reflectivity at the surface of the sample. This dependency leads to distortions in the [...]
