Geometrical product specifications (GPS). Surface texture: Areal. Design and characteristics of non-contact (confocal chromatic probe) instruments | Status: Current

1 Scope This document specifies the design and metrological characteristics of a particular non-contact instrument for measuring surface texture using a confocal chromatic probe based on axial chromatic aberration of white light. Additional metrological characteristics can be found in ISO 25178‑600. Because surface profiles can be extracted from areal surface topography data, the methods described in this document are also applicable to profiling measurements.
