Webinar Summary

Explore Fast, Accurate Techniques for Advanced Materials Characterization

Tackling global challenges often requires the development of new, increasingly advanced materials; these support efforts to build a neutral carbon dioxide economy, improve energy efficiency, develop high bandwidth communication, and identify better methods for preventing and fighting pandemics, among others.

Yet new materials development evolves quickly, driven by innovation in the capabilities and capacity of R&D equipment and processes. As a result, dedicated, high-performance characterization tools are increasingly important in a wide range of fields ranging from geology to optoelectronics.

Geared toward materials scientists, bio-mechanical researchers, geology & nuclear waste researchers, materials development researchers & engineers, and waveguide optical developers, this webinar includes:

  • A comprehensive explanation of roughness considerations like waviness, roughness and spatial filtering;
  • Steps for the ISO-compliant set up and post-processing analyses of mean roughness measurements;
  • An exploration of both profile and areal based measurements, with emphasis on their differences; and
  • Practical examples from experts in the field.

Understand the advanced materials characterization techniques driving innovation in materials research and development

Watch this webinar to gain new insight into:

  • When and why to use profile- and areal-based profilometry techniques for advanced materials R&D
  • How to set up ISO-compliant measurements and post-processing analyses
  • Best practices and key considerations for advanced material research
