Water and other materials absorb light in the infrared range. Water and other materials can be differentiated through different spectral ranges. The moisture content and basis weight of different materials can be determined by measuring the weakened radiation.
IR measurement is especially suitable for the area of residual moisture and all materials that exhibit an absorption spectrum in the infrared range. The complete product thickness can be measured with a transmission measurement. This is necessary when the total composition of the material is of interest.
