FISCHER│Lars Anklamm, Terahertz – the revolution in coating thickness measurement

▶Measuring with Terahertz – how does it work?

• Terahertz radiation consists of electromagnetic waves with frequencies ranging between 100 GHz and 4 THz

• The THz pulse can penetrate many paints and coatings but is partially reflected at the transitions between the layers

• Based on the differences in time between the reflections, the Fischer software can determine the thicknesses of up to four layers

🚩Characteristics

• Measurement of multiple layers on metal and plastic

• The measurement is non-destructive and contactless

• Samples do not require preparation for the measurement

• Very low calibration effort

• No ionizing radiation

🚩Your advantages

• Whether metal, plastic or ceramics – the substrate does not influence the measurement

• A 4-layer system can easily be analyzed in one second

• Wet coatings can be analyzed in running production

• The devices do not require any radiation protection
