EUROMET #610: Comparison of reference laser interferometer systems

Popis výsledku v původním jazyce

Laser interferometers as most precise displacement measuring devices serve as a basic tool for providing traceability from primary wavelength standards [1] (which realize current SI definition of the metre) to broad area of dimension measuring instruments. In principle, the relative uncertainty of 10 10 (0.1ppb) is possible in vacuum, where only wavelength uncertainty, alignment and diffraction contribute to uncertainty. While measuring in air, the instability and uncertainty of refractive index correction are most significant. EUROMET project 610 was running in the years 2001-2006. It was an informal comparison with the goal to exchange experience in using and calibrating counting interferometers. Instruments HP/Agilent 5519 (A or B) of several national metrology institutes - OMH (Hungary, 2001), BEV (Austria, 2005), JV (Norway, 2005) and SMU (Slovakia, 2006) - were one by one compared with the laser-interferometric comparator IK-1 of CMI (Czech Republic), which provided sufficiently
