Thin Film Measurements

Accurate measurement of thin films and coatings on metal substrates is crucial for various industrial applications, including quality control and material characterisation. Sonemat leverages electromagnetic acoustic transducer (EMAT) technology to offer precise, non-contact measurements of coating thicknesses down to the micron level. Our advanced range of bulk wave probes and electronics ensures reliable and efficient detection of thin films.

Introduction: The Importance of Thin Film Measurements

Thin film measurements are essential for ensuring the performance and longevity of coated materials. Traditional contact methods can influence the resonant frequency of the substrate due to mass loading from the transducer or couplant. Sonemat’s EMAT technology overcomes these limitations by providing non-contact measurements that maintain the integrity of the resonant frequency.

How EMATs Measure Thin Films

EMATs detect coating thicknesses by measuring the shift in the resonant frequency of a coated metal plate. Since EMATs do not physically touch the plate, they eliminate the interference caused by mass loading, ensuring accurate and repeatable measurements. This technique is particularly effective for coatings on metals where precision is paramount.
