Microcam-3D/4D profilometer

for high-precision non-contact 3D metrology

Microcam-3D/4D fiber-based optical profilometer provides:

  • Non-contact surface and cross-sectional inspection for a wide range of industrial metrology applications
  • 3D measurements and imaging – geometry, GD&T parameters, roughness, thickness, vibration, defects
  • High speed, sub-micron resolution, excellent repeatability
  • Ease of use for manual or automated applications
  • Modularity and versatility with fiber-based probes that reach into hard-to-reach spaces

Notably, the same profilometer is capable of measuring roughness, GD&T parameters, and defects. This versatility allows many of our clients to use the system for a variety of related inspection tasks.

Overview of features and benefits


  • Optical, non-contact, non-destructive
  • High speed: 2 to 100 kHz and higher
  • Sub-micron resolution, excellent S/N ratio
  • 2D and 3D surface and subsurface characterization
  • Thickness, roughness, vibration
  • Long stroke profilometry


  • Surface profiles
  • Cross-sections (B-scans, C-scans)
  • Volumetric images

Fiber-based probes

  • Inspect inside bores, tubes, and crevices
  • Provide versatility for high-speed online inspection

  •  Wide range of materials: metal, plastics, polymers, glass, metal coatings, silicone, adhesives; reflective, transparent, semi-transparent, specular, nonspecular
  • Wide range of objects and surfaces: objects can be small (several microns wide) to large (no upper limit), stationary or moving, solid or liquid, and include interiors of bores and tubes, exteriors of cylinders, concave or convex spherical shapes, extremely hot or cold, radioactive
  • Versatility of setup: Non-contact probes work up to 1 m away from surface and more than 1 km from interferometer
  • Small-diameter probes reach in to measure insides of bores and small-diameter tubes
  • High-aspect-ratio surface features can be acquired: channels, grooves, steps, sharp edges, and more
  • Continuous, long profile scanning: no area stitching required
  • Option of multiplexing probes with single interferometer for additional ROI
  • Easy integration of fiber probes in labs and in process: on XY tables, on multi-axes scanning mechanisms, inside machining centers, above moving webs, etc.
  • Rugged probes: inspection possible in hostile environments where humans cannot work
  • USB connection for data transfer from interferometer to PC or laptop
