The TranSpec gauges permit the film thickness
measurement of dry or even wet lacquer coatings, with the possibility of a simultaneous
two-layer control. Our technology is used by the world's leading manufacturers of Automobile
Headlights and Compact-Discs.
The picture shows a 3D film thickness profile of the protective lacquer of a standard
commercial Compact-Disc in the range of 9-13 µm. Note the spot where the liquid lacquer
has been dropped during spin coating !
