Surface Metrology: Precision Measurement for Critical Surfaces

Surface Measurement, Step Height Measurement, surface defect & Roughness Measurement

At Omniscan, we specialise in surface metrology, providing equipment for high-precision measurement and analysis of surface texture, roughness, flatness, and form. Whether you’re developing advanced materials or ensuring the quality of critical components, accurate surface characterisation is key to performance, reliability, and compliance.

What is Surface Metrology?

Surface metrology is the measurement of a material’s surface topography. It quantifies features such as peaks, valleys, texture, and waviness—elements that influence product behaviour in real-world applications. From aerospace and automotive to optics, medical devices, and semiconductors, surface properties can determine how components wear, reflect light, bond, or function under stress.

Omniscan’s Expertise in Surface Measurement

Using advanced non-contact optical systems, Omniscan solutions can deliver detailed 2D and 3D surface data with sub-micron resolution. Our technology enables rapid, repeatable measurements across a wide range of materials and surface finishes, including metals, glass, polymers, and coatings.

We work with a variety of surface metrology methods and instruments, including:

  • White Light Interferometry
  • Low Coherence Interferometry
  • Coherence Scanning Microscopy
  • Fringe Projection Systems
  • Laser line profilometry

These methods allow us to assess surface roughness (Ra, Rz), step height, flatness, curvature, and texture—essential for both functional and aesthetic requirements.

Applications of Surface Metrology

Our measurement services support industries such as:

  • Aerospace: Assessing wear and fatigue-critical surfaces
  • Automotive: Ensuring proper sealing, adhesion, and lubrication
  • Medical Devices: Verifying implant surface roughness for biocompatibility
  • Optics: Measuring flatness and form for high-performance components
  • Electronics and Semiconductors: Surface uniformity and coating validation

Whether you’re troubleshooting a process, validating part quality, or conducting in-depth R&D, Omniscan provides the surface data you need to make informed decisions – get in touch today.
