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 [...]
