Rubert 564 | Precision Reference Specimen | Pyramidal Frustum, RSm = 250 µm, Pt = 20.25 µm
The Rubert 564 is an electroformed nickel precision reference specimen with a pyramidal frustum structure, used for checking and calibrating surface measuring instruments. Its parameters are RSm = 250 µm, Pt = 20.25 µm. Note that in-house UKAS calibration is not available for the 3D areal specimens 561–564. It is offered in two versions: 564E, with a hard nickel-boron top layer, and 564X, without a top layer.
