The high accuracy of the Leitz PMM-C Infinity makes it possible, in the production, to make the correct decisions and to keep the cost of producing parts at a minimum. A high parts throughput is achieved from the dynamic single-point probing and the serial High-Speed-Scanning (HSS) of known and unknown contours.

The Leitz PMM-C Infinity carries out any measurement task with the highest precision regardless of whether on prismatic workpieces or parts with highly complex geometries – such as cylindrical or globoid stepping gears. In particular, part measurements with very close tolerances require a coordinate measuring machine like the Leitz PMM-C Infinity for the highest precision.

With horizontal probe extensions of up to 800 mm length the continuous High-Speed-Scanning probe head LSP-S4 allows the measurement of features deep inside a work piece. Its integrated automatic weight balance system can carry styli configurations of up to 1000 g.

In addition to its ability to accept long styli, the LSP-S4 excels with its low trigger forces – ideal for measuring delicate surfaces. Its long travel means that the LSP-S4 is not susceptible to damage caused by collisions.

Probing deflections are measured via high resolution Linear Variable Differential Transducers (LVDT). The LSP-S4 supports all the standard probing modes like Single Point Probing, Self-Centering as well as Continuous High-Speed-Scanning for fast and accurate form and profile measurements.

Like all other Leitz probe heads, the LSP-S4 provides simultaneous and unclamped probing in all axes, always orthogonal to the surface. This allows the correct compensation of any styli deflection.
