Optical Coherence Tomography Profilometer System

Across industries

The list below presents our typical metrology solutions by industry.  Due to limited space and since new applications of low-coherence interferometry are discovered daily, this list is not exhaustive and requires periodic updates. If you do not see your industry or application listed, we encourage you to contact us and we’ll be happy to discuss your particular metrology needs.



  • Engine blocks – 3D inner surface inspection and imaging
    RS2, a micron-precision non-contact optical scanner probe, acquires the ID of several valve bores in a valve body as part of a fully-automated digital inspection. Benefits: 3D interactive modelling of valve bores, measurements of distance, position, cylindricity, surface/dimensional defects, roughness, geometric tolerances of internal features, dimensional deviations, and more.
  • 3D surface inspection and imaging of components – see 3D metrology in hard-to-reach spaces (tubes, bores, cylinder interiors) and high-aspect-ratio features (steps, grooves, channels, blades)
  • 3D valve  inspection – inside diameter and surface
  • Diesel injector and nozzle interior inspection
  • Inspection of component mold interiors
  • Detection of casting defects
  • Thread and thread height measurement

Bio-medical (see also Medical devices)

  • Coatings which protect devices from corrosion or patients from complications – see thickness measurement


  • 3D inspection of dental implants

Electronics and microelectronics

  • Chemical mechanical polishing (CMP) pad surface quality inspection – see how we measure roughness and high-aspect-ratio features (such as CMP surface channels)
  • Thick film photoresist coating on electronic wafers – see thickness measurement
  • BGA inspection
  • Flatness, coplanarity,  and warpage measurement



Hostile (harsh) environment measurements across industries

Machining (precision machining and mechanics, tool machining)

  • Edge inspection (precision tools, etc.)
    EdgeInspect: MicroCam-3D profilometer with a non-contact fiber-based optical scanner provides micron-precision 3D characterization of edges. In this configuration, a drill bit is rotated on a chuck base while the scanner inspects the item top to bottom following a user-defined scanning sequence. Benefits: capability of 3D interactive modelling of the entire inspected tool, option to automate pass-or-fail reports, 100% user-defined measurement parameters, measurements of edge sharpness, edge radius, and more.

Military and defence

  • 3D tube ID/OD inspection of gun barrels, scopes
    MicroCam-3D Tube ID Scanner, a non-contact optical measurement system, provides micron-precision 3D characterization of tube and bore interiors. Benefits: complete geometry of structures up to 30” long, capability to survey every detail (chamfers, rifling, grooves, lands, edge breaks, etc.), fully configurable automated digital inspection, detection of micron-size dimensional or surface defects  (porosities, cracks, scratches), surface roughness acquisition, and more.
