How it works?
Discover das-Nano in action
das-Nano has met Volkswagenās challenge with its patented terahertz-based technology for contactless, layer-by-layer coating thickness measurement. Selected through an international tender, das-Nano’s terahertz technology became the worldās first fully operational paint thickness inspection system at Volkswagen Navarra in July 2020.
Running 24/7 since its installation, it provides real-time data on the painting process, enabling process costs reductions through reduction of material, energy, and defect minimizationādelivering both economic and environmental benefits.
And in 2026 we reached another milestone: the first terahertz thickness measurement solution for trim parts was installed at BMW Group Plant Leipzig by das-Nano.
Any color and any plastic trim part shape and size can be inspected in-line with the same das-Nano terahertz technology used for metallic car bodies. This has been a hugh step for BMW Group since it substitutes a destructive and time-consuming inspection testing by a contactless and non-destructive testing (NDT) by das-Nano.
