A hard gold-plated parabolic mirror reflects the measuring spot onto itself. The radiation emitted from the object is “captured” in this way. Multiple reflections result in a significantly higher radiance in this area than the object surface emits. With the LT15 EB it is therefore possible to measure the temperature on shiny, highly reflective surfaces without contact.

The measurement is based on the ratio of energy received in two neighboring narrowband spectral ranges. This measuring principle eliminates radiation differences due to dust, smoke or dirty windows that affect both wavelengths equally. The target emissivity does not have to be known and parameterized for when the ratio involves ‘graybody emissions’ ie, when emissivity is the same in both wavelengths.
