Stylus and Optical Profilometry Webinars

Qualifying Surface and Device Performance Through Roughness Quantification

Learn how to measure micro-roughness in accordance with the ISO 25178 norm to assess device performance and efficiency and, ultimately, improve product and process design


Accurately quantifying surface roughness allows users to determine where  defects and other sources of device inefficiency originate in the process and work to eliminate them.

This webinar focuses on the use of non-contact optical profilometers and related analyses to accurately measure micro-roughness of surfaces, rank materials, and assess (and improve) product design efficiency and performance.

Understand the Full Functional Importance of Surface Texture Parameters

The 3D areal surface texture analyses made possible by advanced optical profilometry techniques are ideally suited for more than just quantitative defect detection and correction; mean roughness and other areal roughness parameters can be used to differentiate surfaces and quantify their efficiency for intended applications.


Geared toward scientists and engineers working in R&D, Process and Quality Control, and/or interested in characterizing the metrology, tribology and surface related performance of materials and devices, this webinar explains:

  • How and when to use areal (instead of profile) measurement methods given the intended application;
  • The benefits of data analysis using the 3D international standard ISO 25178 norm;
  • How these analyses can be exploited to rank surface properties and explain wear processes; and
  • 3D optical profilometry as a method of correlating micro-roughness to surface and device efficiency.


The presentation includes case studies from the automotive, sensors, optics, and medical industries.
