Dimensional Measurements

Examples at traceable standards

   

Example: Outer size measurement at a block:

Sample: Precise metal block previously measured with metrology instruments in a calibration laboratory:

Result:

Reference 3D Nanofinger® Difference
40,000.080 um 40,000.129 um 0.049 um = 49 nm

By measuring a set of such parameters it is possible to determine e.g. the central axis of a cylinder, the center of a hole or the zero-point of the 3-dimensional coordinate system from a sample.

 

Many other examples of dimensional measurements are described in the area of 2D and 3D Profile Measurements, see for example:


 

Summary:
Dimensional features and 3D-Profiles and Roughness parameters are measured with the same machine:
the 3D-Nanofinger®.
