Our working group offers calibrations for roughness standards in the range from Rz ≥ 0.150 µm to Rz ≤ 50 µm.
In addition, groove standards and depth-setting standards from 0.005 µm to 100 µm can be calibrated.

For other standards, please contact us.

The properties of a surface are characterized by a multitude of parameters, the majority of which are defined in the standards for surface metrology. Our working group's task consists in calibrating these parameters for measurement standards used for the calibration of surface measuring devices.
The aim of this working group is to achieve a better comparability of the measurement results obtained when calculating surface parameters.
