Do you want to characterize the surface of your samples by profilometry? Calnesis provides this type of service.

What is profilometry?

Profilometry is the measurement of relief. This analysis makes it possible to evaluate the roughness of a sample and can be carried out along an axis (2D) or along a surface (3D).

What techniques can be used?

The objective of the measurement is to establish an altitude profile of a sample. For this, there are two groups of techniques: so-called “contact” techniques and so-called “contactless” (optical) techniques. The technique chosen depends on the materials to be analyzed and the desired resolution.

What are generally the deliverables of a profilometry study?

The deliverables of a study are generally representative images of the analyzed surfaces, relief curves along chosen axes, and finally roughness parameters calculated from the reliefs.
