Measurement and Inspection of Membranes

The station employs a combination of different probes based on Marposs-STIL proprietary chromatic confocal technology, which are mounted on machine-controlled axes to automatically perform measurement or retooling strokes.

The MC2 linear confocal camera guarantees the acquisition of very high resolution images with perfect focus on a depth of field up to 2.6 mm, normally unimaginable for high resolution cameras with conventional optics. A very high sampling frequency allows the surface to be scanned in a short time, detecting different types of defects.

The use of MPLS line confocal sensor in combination with the machine axes allows an evaluation of x-y-z dimensions of the component as a whole, as well as of the potential defects that have been identified. Finally, the complete dimensional characterization of these defects makes it possible to evaluate which ones may actually be dangerous for the functioning of the component, enabling the adoption of appropriate corrective actions.

Depending on the type of component and the required controls, it is also possible to integrate different configurations of probes based on different technologies, such as laser profilometers, confocal or interferometric point sensors, linear or matrix cameras.

For example, the use of a point confocal sensor can be used for the control of flow plates and BPPs in order to perform an accurate scanning measurement of the depth and width of the feed channels.
