The laser-based layer thickness measurement system from Enovasense measures non-destructively, without any contact with the object. The opaque, semi-transparent or transparent coating is measured from a working distance of 5 to 20 cm using laser and infrared sensors. And this under industrial environmental conditions, i.e. also on conveyor belts, at high temperatures and in a wet or brittle condition. The system is based on the thermophysical measurement principle and is therefore suitable for almost all layers on all common substrates, such as paint, electroplating, metal coatings on plastic, metal, wood or glass.

The process suitability is unique, allowing 100% quality control in many places where this was previously not possible: Extremely short measuring times of less than one second, the non-contact measuring method and the scalability with up to 10 sensors that can be controlled in parallel all play their part. A robot arm assembly is also possible with this system without any problems. The small dimensions of the measuring head (75 x 32 x 41 mm with a weight of 150 g) enable measurements in places that were previously absolutely inaccessible.

The process is based on a physical model that allows the system to be pre-calibrated according to the application. The calibration is both faster and easier to implement than with conventional methods. For some applications, calibration can even be omitted entirely.
