Complete solution for
car-body quality

The contactless solution for car-body multilayer thickness measurement

Irys is a contactless system that using Terahertz waves and proprietary algorithms developed by das-Nano provides the thickness measurement of every painting layer in a car body in a non-destructive way.

No damage

Pioneers in the automotive industry

We have installed the first THz-based system in the world for the in-line control of the layer thickness of the car body coatings.

Our THz technology was chosen after an international tender by the leading car manufacturer, Volkswagen (VW), for the world’s first installation of the paint thickness inspection system at Volkswagen Navarra’s facilities in July 2020. IRYS system has been successfully in full operation since then, generating real-time data 24/7, and has allowed VW to have a better, cost-saving and sustainable painting process.

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.
