R-Parameter (2D) S-Parameter (3D) R-Parameter on an area Stilus tip simulation 2D-Roughness (R-Parameter): With our profilometers you can determine roughness in seconds in 2D, whether you’re interested in average roughness (Ra), roughness depth (Rz), or total profile height. 3D-Roughness (S-Parameter): 3D roughness measurement captures the entire surface structure, offering a more comprehensive view than 2D profile measurements. Our software makes analyzing S-parameters, such as mean arithmetic height (Sa) or maximum height (Sz), fast and easy. Simply select the area and analysis type, and results are calculated instantly. Options like S- or L-filters can be adjusted with just a few clicks. R-Parameter on an area: In addition to the acquisition of R-parameters via individual profiles, you also have the option of determining the maximum, minimum, mean or median values of all profiles over a 3D surface. This enables a comprehensive analysis of the R-parameters over the entire examined area and offers a holistic perspective on the surface structure. Stilus tip simulation: The results of the optical roughness measurement can be compared directly with the results of traditional tactile measurement methods using the stylus tip simulation. This enables a consistent evaluation and interpretation of the surface structure regardless of the measurement method used.
