With the newly developed MPLS180 style, a unique opportunity for online quality control is available. The proven chromatic-confocal measurement principle is implemented in a line sensor consisting of 180 individual measuring points. With a throughput of 180 line taps, a measurement of 324,000 points is possible. Since the points are measured in separate channels, an overspeak is excluded. Even highly reflective points do not hinder the measurement of points with low reflectivity. The usual high accuracy and resolution of the point sensors is also preserved for line sensors.
