WebSpherical surfaces are defined by the radius of curvature with a dimensional tolerance . This tolerance indicates the range within which the actual surface is contained. The radius of curvature tolerance can also be defined by interferometry, but more on that later. For cylindrical surfaces, use Rcyl instead. ISO 10110‐1 Dimensioning
