Surface profile is a key parameter of a product's quality, which affects the product's overall performance. The height values (oftenly refers to the valleys and peaks) of the surface determines many functional features, eg. abrasion resistance, adhesion, etc.
Furthermore, the analysis of wear or abrasion rate after the mechanical tests is also needed to evaluate the quality of surface coatings. Therefore, an accurate measurement and documentation of the surface profile helps to make the right decision for the quality control.
Optotop® is a testing instrument which measures the surface profile in a non-contact fashion. The highly accurate measurement of the 3D topography makes it widely used in R&D for new materials development as well as in the quality control of manufacturing processes.
Parameters which can be measured with Optotop® include:
Macro & micro geometries
Effective contact area ratio
Easy and comfortable handling
Rapid data acquisition
Robust measuring method for various materials, coatings and samples
Micro roughness index number for linear profile
Direction-derived roughness index number of areas (texture-orientation analysis)
Topography as 2-D-line profile, 3-D-display and height profile
