Teratonics Stripp Control can be directly deployed on a production line to perform 3D measurements and to detect defects in 100 per cent of the production, in a fully automated and Industry 4.0 way. It reveals the invisible inside many electrically non-conductive materials, for example plastics, ceramics, paper, semiconductors. Components can be controlled in their pure form, but also in a heterogeneous state, such as a foamed plastic or a composite. 

Assemblies between two dielectric units or between a dielectric and a conductive unit can be analysed in the dielectric volume and in particular in the bonding transition between the two units. Moreover, the powerful depth resolution gives access to thickness, with a micrometer precision that is adapted to many coatings and that can resolve also individual thickness in multilayer coatings. 

With the very immediate feedback to the production, bad parts can be sorted out to be scrapped or reworked. Often the production process itself can be optimised to avoid the fabrication of bad parts and to reduce the waste of raw materials, energy, and time. All this helps to reduce the global costs.

This transformation of quality assurance and quality control is enabled by Teratonics’s internationally patented technology: it uses the Terahertz (THz) frequency range - the last part of the electromagnetic spectrum to be exploited in the industry - and allows therefore flexible non-contact analysis, without danger to the health, without the need for radioprotection. Its unique ultra-fast single-shot detection decreases the point measurement time by a factor of about 10,000,000 compared to the state of the art of pulsed THz. 3D imaging of internal structures permitting also precise wall thickness measurement and high probability of defect detection becomes possible in the production cycle time of many industries. This breakthrough THz hardware is complemented by a proprietary software for an automated scan motion and data processing.
