Photothermal technology enables the non-contact and non-destructive measurement of the coating thickness of a variety of different coatings on almost all substrates. In our White Paper, we present the physical principles of this flexible technology. We also explain the advantages of continuous excitation using a modulated light source, as used in the CoatPro and CoatPro XD measuring system, with which we achieve high precision in determining the coating thickness for almost any material.
Further articles will follow at irregular intervals.
