Length Laboratory
Tasks:
Maintenance of the national measurement standards for length, plane angle, refractive index and optical rotation.
Ensuring traceabilty in the field of length, plane angle, refractometry and polarymetry.
Performing the research in the field of light frequency of stabilised lasers, measurements of length, plane angle, surface texture parameters, refractive index and optical rotation.
Performing tests and checks for the needs of legal metrological control, conformity assessment and type approval.
Organizing and taking part in national and international compa- risons.
