Laboratory of Geometric Measurements

The Laboratory of Geometric Measurements has modern equipment for measuring and monitoring geometric quantities of surface roughness parameters, geometric shape characteristics and geometric dimensional characteristics. The measurement and monitoring of geometric dimensional and shape quantities can be performed by the contact method, the non-contact method by image capture or the non-contact method by emitting a laser beam.

For more detailed information on the measuring and monitoring equipment see the “Technical specifications” tab. The range of standards according to which the measurement and evaluation take place can be found under the “Range of standards” tab.
