Rubert 604 | 3D Areal Calibration Specimen | ACG Cross Grating, 0.03 µm Height, 5 Pitches
The Rubert 604 is a type ACG areal cross grating with a 0.03 µm height, made by Rubert for the UK National Physical Laboratory's set of eight physical material measures for calibrating areal surface topography instruments. The grating carries five pitches of 400, 160, 100, 40 and 16 µm on a single artefact. In-house UKAS calibration is not offered; calibration by other laboratories can be arranged on request.
