Laser triangulation is used as a non-destructive method in coating thickness measurement.
Coating thickness measurement is used to determine the thickness of coatings on components and substrate materials. Depending on the type of coating, the material of the substrate and the coating thickness, different methods are used. Single layers as well as multi-layer systems are measured. Coating thickness measurement is a variant of thickness measurement in which the thickness of a body is determined.
Thickness measurement of entire surfaces
Coating thickness measurement deals with determining the thickness of coatings and metallic overlays on surfaces. Coating thickness refers to the thickness of an applied coating such as plastic on a base material. There are single coatings and multiple coatings. Thickness measurement always records the total thickness of a material or component.

Thickness measurement of entire surfaces in throughput
In coating thickness measurement using QuellTech laser line sensors, a laser profile is projected onto the material and simultaneously onto an uncoated part of the substrate. By difference formation, the coating thickness can be calculated. In the course of a coating process, the total thickness of a substrate can be recorded simultaneously by measuring from two sides. The difference before and after coating gives the coating thickness.
Coating thickness measurement and thickness measurement with QuellTech laser line sensors has the advantage that these offer the possibility of recording the coating thickness or thickness over the entire surface of a substrate. In contrast to many other methods, which only perform point measurements, this method enables an area-wide detection.
In the production of battery foils, it is of great importance to monitor the variations in layer thickness across the entire surface. The QuellTech laser line sensors are characterized by their high speed, making them ideal for “in-line use” in production processes. This allows real-time monitoring of thickness and film thickness over 100% of the battery film area without time delay.
Coating thickness measurement makes a valuable contribution to improving product quality and efficiency in the following areas and applications:
Thickness measurement by differential measurement
In the past, we have used Quelltech solutions for Coating Thickness Measurement in a wide variety of projects. Here you can find a small excerpt of these projects:
The QuellTech Q6 laser scanner product series is particularly suitable for precise coating thickness measurements and thickness measurements at low coating thicknesses that require high Z-resolution and tolerance. The high travel speed of the Q6 laser scanners also enables successful use in inline production processes.

Both product families, the Q5 and Q4 laser scanners, are also suitable for layer thickness measurement and thickness measurement, if the requirements for the measurement are not so high, e.g. for cladding of pipelines.
