FTP Combined Top-Bottom
Functionality and quality of industrially manufactured components relies on well-controlled and well-monitored machining processes. Quality control, close to line or inline quality inspection often uses surface metrology for evaluating form, roughness and other surface parameters.

Now, Polytec enhances the perspective for valid measurement results, providing a combined top & bottom topography in a single, but areal and direct measurement.

Sometimes, the combined look on front and back sides of a workpiece is indispensable for a comprehensive quality analysis. This might require swapping or flipping the sample, or using an additional reference surface as indirect measurement, or applying two sensors each from one side. Each approach can lead to additional measurement uncertainty.

The FTP measuring module for back and front measurements can become a game-changer in quality control of precision mechanics such as in the watch-making industry, for sealing surfaces, shim rings or optical components and more.
