An Optical 3D Nano Profilometer is an advanced, fully non-contact measurement system that combines optical technologies with imaging interferometry to enable nanoscale characterization of surface morphology, roughness, and step height. By completely eliminating physical contact with the sample, the system minimizes the risk of mechanical damage to sensitive specimens, including biological materials, polymers, adhesives, and transparent or semi-transparent surfaces, enabling measurements without introducing any physical disturbance. Key advantages of the system include broad compatibility with a wide range of materials, the ability to characterize complex geometries such as spherical surfaces, high measurement accuracy, and complete elimination of contact-related sample damage. The Nano-Profilometer offers a wide range of applications across both industry and research. It can be used in aerospace, automotive, biomedical engineering, optics and photonics, and metallurgy, particularly for coating-thickness measurements. Additional applications include 3D printing, microfluidic devices, materials research, geological studies, and the conservation and restoration of historical artifacts
