Table of Emissivities in Three Popular Spectral Regions

May 9, 2009

The Table of Emissivity on the INFRAPOINT Messtechnik GmbH website, posted in 2009 (No longer available online) had 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 [...]

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 [...]
