In-Situ Measurement

In the coating industry, not only the technical properties of the coated product are relevant for quality assurance (QA). Short ramp-up times and fast failure detection are also essential to keep coating costs at bay. Hence, inline measurement systems are commonly used and nothing new. There are in-situ measurement systems inside the coaters and ex-situ systems for measurements outside them.

In-situ measuring systems combine the results from different coating steps within the coater and help monitor the coating process. They are essential for quality control and for minimizing the time for adjustments. Therefore, the layers are characterized and monitored by measuring their transmittance, reflectance, resistivity and other optical properties.
