Fischer: Multilayer coating thickness measurement with terahertz waves

The Terascope from Helmut Fischer enables the non-destructive and non-contact measurement of organic single and multiple layers on any base material. Up to seven layers can be analyzed in detail within a few seconds and with just one measurement. Harmless terahertz waves penetrate organic materials such as plastics, wood, ceramics, paints and many more, regardless of the base material, thus opening up a wide range of applications in industrial metrology. "We use the Terascope to measure single and multi-layer systems made of organic materials, such as paints and varnishes, in a non-contact, non-destructive manner and within seconds. THz technology also makes it possible to check specific material properties," explains Dr. Martin Leibfritz, CEO of the Helmut Fischer Group. With an outstanding bandwidth of up to 6 THz and in combination with the patented clean-trace technology, the measuring system guarantees high-precision measurement results and high repeatability. Thanks to the high sampling rate of 1.6 kHz, measured values are recorded quickly and reliably, even in harsh environments. Optimized for automation, the compact measuring head positions itself optimally to the measurement object using an optional highly sensitive 3D scanner. This means that even curved and complex-shaped surfaces as well as wet and soft coatings can be measured easily and with market-leading measurement performance.

The robust measuring system enables measurably more effective and economical processes in quality control. Used to measure coating thickness, determine radar transmission and reflection or even to detect invisible defects and hidden corrosion - the Terascope provides targeted support in saving resources and costs by delivering high-precision and detailed measurement data for quality assurance quickly, fully automatically and non-destructively. The measuring system can be flexibly and easily integrated into new or existing plants and process control systems by plant manufacturers and integrators. The Terascope is designed for uninterrupted 24/7 use. The state-of-the-art measuring head measures electro-optically, making it particularly low-maintenance. The measuring system guarantees maximum reliability thanks to automatic regular referencing. The Terascope also makes no compromises when it comes to software. The powerful and smart Tera Suite controls the measuring system and enables full data control and resource-saving energy management.
