Fast and accurate measurements with long styli and heavy styli configurations – that’s why the Leitz LSP-S2 probe head was developed. It is used in all Leitz PMM-G and PMM-F coordinate measuring machines. The Leitz LSP-S2 features a maintenance free measuring touch system which recognizes the normal direction of the surface, independent of its moving direction. The axes of the probe head are not clamped during the measurement; this means that the deflection of the measurement system always takes place perpendicular to the workpiece surface. The actual direction of the normal to the surface is determined in every probing point. Bending of the styli are always compensated correctly. The Leitz LSP-S2 combines outstanding accuracy with an
