* - the average meaning, written on the grating's box, is based on the measurements of 5 gratings with the same height (from the batch of 300 gratings) by AFM calibrated by PTB certified grating set TGS1. This value is more exact than Basic step height. Basic step height can vary depending on different batches and is specified above.
