Pioneers in the automotive industry

We have installed the first terahertz-based system in the world, in Volkswagen, for the in-line production control of the film build thickness of the car body coatings.

The Irys system works successfully from July 2020 and enables you to have a better, more economical and sustainable painting process. The system generates data in real time 24/7. 

Do you want to reduce error costs? This is your opportunity.

A complete portfolio to meet all your manufacturing process needs


Irys is a Terahertz Film Build Measurement technology that allows you to measure the thickness of each coating layer in a contactless way, causing no damage to the surface, it allows your company to increase control in the manufacturing process, reducing costs and environmental impact.


Onyx is the first system in the market designed to provide a full-area non-destructive electrical characterization of Graphene, thin-films, and other 2D materials.


Notus enables the contactless inspection of the full layer coating on top of composite materials used in the wind and aerospace industry. Notus provides information about the thickness of each layer and adherence between layers, reducing costs and environmental impact of the coating processes.


You can only make the right decisions if you have the right information. Our Big Data Analytics tool examines and graphically represents all the information of your process under a user-friendly interface with a customized degree of interactivity.

Our clients are our best reference

Through extensive testing in a production equivalent area, das-Nano has demonstrated a high degree of accuracy for measuring the coating layers of our vehicles. This is a great example of Toyota’s quest for continuous improvement.

With previous methods, it was still necessary to make scratch bodies, mask them off and manually measure the layer thickness. So now we have significant time and material savings with this novel system. You get much more information compared to previous systems.

Claudio Sole
Paint Expert at Volkswagen Headquarters in Wolfsburg

Due to the obsolescence of our previous measurement systems, the Wolfsburg planning department and our technology partner das-Nano, decided to introduced an installation based on Terahertz technology. This system allows us the simultaneous measurement of all paint layers in a fully automated way eliminating manual processes.
