The Wafer configuration of the DSA100 Drop Shape Analyzer is geared towards the automatic, standardized quality control of wafer surfaces and other round samples. The instrument precisely determines the homogeneity of the cleaning of a surface based on the contact angle. It also enables coatings to be characterized, for example by differences in wetting of exposed and unexposed photo varnish.
