Theta Topography is an innovative system capable of separating the effect of surface roughness to the contact angle result. As a result, roughness-corrected contact angles can be better compared with each other for research and quality control purposes.

Features & Benefits

  • Integrated methodenabling to define contact angle and surface roughness accurately from the same location and to combine both surface chemical and topographical data with automated software calculations.
  • Offers fast surface characterizationmethod, which does not demand specialist to run the samples.
  • Versatile roughness measurement: both 2D and 3D characterization..


Many surface modification and coating technologies that are used for optimizing wetting and adhesion properties influence both surface chemistry and roughness. Understanding the mechanisms that impact wetting by separating these two factors can be a useful tool in product development processes and in quality control. Roughness correction on contact angles also enables the calculation of fundamental surface free energy on rough surfaces. Theta Topography can be used for studying microscale roughness, which is relevant in many applications and processes. Examples include:

  • Coatings and surface modifications
  • Paper and board wettability
  • Biocompatibility of implants
  • Construction and building material
