Basics 4 Basics 4.1 Measurement of Infrared Temperature Everything emits an amount of infrared radiation according to its surface temperature. The intensity of the infrared radiation changes according to the temperature of the object. Depending on the material and surface properties, the emitted radiation lies in a wavelength spectrum of approximately 1 to 20 μm. -

Page 36: Appendix
Appendix 10 Appendix 10.1 Determination of Emissivity Emissivity is a measure of an object’s ability to absorb and emit infrared energy. It can have a value between 0 and 1.0. For example, a mirror has an emissivity of 0.1, while the so-called “Blackbody“ reaches an emissivity value of 1.0. - Page 37 Appendix Emissivity values shown in the table are only approximate, since several parameters may affect the emissivity of a material. These include the following: Temperature Angle of measurement Geometry (plane, concave, convex) Thickness Surface quality (polished, rough, oxidized, sandblasted) Spectral range of measurement Transmissivity (e.g.
