摘要

Twelve participants, all from different countries, participated in a comparison on pitch measurements of 1D gratings which ended in summer 2000. Two holographic gratings with pitches of nominally 290 nm and 700 nm served as standards. The main methods used by the participants were optical diffraction and scanning probe techniques. For the two gratings the resulting comparison reference value, which was calculated as the weighted mean of all measurements, has a combined standard uncertainty of only 1.1 pm and 2.3 pm, respectively. All but two of 29 results were in good agreement with the reference value.
