Infralot IMF

Light-specific wavelengths can excite the atomic bonds of certainmolecules to oscillate. These amount to a multiple of the basic resonance of the molecules. A large part of the incident light energy is absorbed by the material being measured.

If the light energy reflected or transmitted by the material to be measured is examined separately for each wavelength, a relationship is established between the degree of absorption of this resonance wavelength and the number of absorbing  molecules. Dependent on the moisture content in the product, the light energy absorbed alters significantly at the resonance wavelength of the water molecule.

For stable measurements in practice, the measured light energy of the resonance wavelength is compared with other reference wavelengths at which no absorption occurs.
