Photothermal measurement method for opaque coatings and all common substrates
For many industrial products, the quality of coatings plays an important role. For example, the material thickness, color, gloss, or adhesion of one or more layers on a substrate
Inline measurement system for powder coatings
Powder coating quality depends on thickness and uniformity, especially at critical points. Photothermal measurement systems offer practical solutions for quality control.
Precise layer thickness measurement without referencing
For many products, coating quality is crucial—such as material thickness, color, gloss, or adhesion of one or more layers to a substrate. Regardless of their purpose, measuring the thickness or uniformity …
