Optical Profilometry: Precisely Analyze Surfaces | GBS
In industrial environments and research, reliable surface measurement plays a central role. Precise 3D measurement data form the basis for manufacturing processes, quality control, and product development.
Profilometry allows complex surface structures to be captured and analyzed. Our modern systems are capable of performing these tasks with high speed, resolution, and flexibility. This enables companies to secure their manufacturing processes and develop innovative products.
Why Precise Profilometry Is Crucial
Profilometry refers to the quantitative measurement and analysis of surface structures. This method records height profiles and topographical data to accurately determine roughness, waviness, and microstructures. In practice, a distinction is made between tactile and optical methods.
Tactile devices measure the surface mechanically, while optical systems work contactlessly and capture the entire surface in three dimensions. Companies should therefore rely exclusively on optical profilometry. It enables standardized measurements according to ISO 21920 and ISO 25178 and is used for applications ranging from process monitoring to the development of new materials.
Applications of Optical Profilometry
Surfaces of milled and turned parts are inspected for roughness and microstructure to maintain manufacturing tolerances in the automotive and mechanical engineering industries.
Wafers and microchips are checked for flatness, roughness, and microstructures to ensure process reliability and functionality in semiconductor production.
Implants and medical components are analyzed for surface quality and biocompatibility to comply with regulatory requirements and ensure proper function in the body.
3D-printed components are extensively examined for roughness, defects, and dimensional accuracy to verify process quality and end-product properties.
Tool and Cutting Edge Analysis
Cutting tools and indexable inserts are evaluated for edge radius, microgeometry, and wear to document service life and ensure manufacturing quality.
Lenses, mirrors, and prisms are measured for shape deviations, surface roughness, and coating quality to guarantee optical performance.
Electronics
Manufacturing
Solder joints, contact surfaces, and microstructured components are precisely measured to ensure stable electrical connections and production reliability.
Tribological Testing
Wear surfaces and protective coatings are analyzed for material loss, surface changes, and layer thickness to document the lifespan and functionality of components.
Material samples, test surfaces, and new materials are examined in laboratories for surface structure, roughness, and topography to support development processes and secure innovations.
