NIR spectroscopy for surface inspection

With near infrared spectroscopy systems it is possible to quantify the thickness and determine the consistency of the surface layers. The detectable layers are in a range of some hundred nanometres. The fields of applications range from detection of contamination films after technical cleaning processes to measurement of coatings. A wide variety of testing applications can be covered with this non-visible imaging technology. The presentation will show the possibilities from research intensive applications in laboratories up to process integrated systems in manufacturing environments
