Length Laboratory

Length Laboratory

Published by: Kamila Szulc


Maintenance of the national measurement standards for length, plane angle, refractive index and optical   rotation.
Ensuring traceabilty in the field of length, plane angle, refracto- metry  and polarymetry.
Performing the research in the field of light frequency of stabili- sed 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.


•Calibration of:
–stabilised lasers,
–gauge blocks,
–laser distance meters,
–optical flats,
–ring and plug gauges (internal and external  cylinders),
–1-D measuring machines,
–mechanical comparators for gauge blocks,
–optical polygons, angle gauges, rotary tables, goniometers,
–photoelectric autocollimators, electronic levels,
–visual  and  photoelectric refractometers,
–solid and liquid refractive index   standards,
–photoelectric  polarimeters,
–quartz control plates (polarimetric  standards),
–straightness and roundness standards,
