Thin polyester coating is used to protect steel sheets, used for hi-tech manufacturing, from corrosion. Testing of coating thickness and uniformity is important to ensure the specified performance of the coating. This testing is, typically, done offline for adjustment of manufacturing process.
MProbeVis-MSP offers a quick, accurate and non-destructive method to measure the thickness of polyester films.
Polyester films thickness is notoriously difficult to measure using optical non-destructive methods. The main reason is the texture and micro-nonuniformity of the coating.
In case of non-transparent high-scattering coating, NIR range (MProbeNIR-MSP wavelength 900-1700nm) need to used with the small spot. MProbe MSP system allows to localize the measurement in a small spot. Advance data analysis of the measured data reduces the effects of measurement artifacts due to texture and allows extraction of the thickness data.
