Wide Area 3D Measurement

Wide Area 3D / PATTERNED LIGHT Measurement Services

Covalent uses an optical instrument to measure larger samples: the Wide Area 3D instrument projects patterned light on the surface of an object to measure and identify the surface topography.

  • Full 3D: A 3D model of the surface is created and can be analyzed for dimensions, angles, curvature along specific lines, as well as for flatness. 

  • Speed: Measurements are made with high resolution (height resolution <1µm, width repeatability 1µm) on large (inch-scale) areas within minutes, while traditional CMM is a longer process.

  • Non-destructive: This technique is non-destructive and minimizes the risk of damaging the object since no probe is used in the process.

Below, you’ll find more information about our patterned light/wide-area 3D measurement services and common measurements using our Keyence wide-area 3D instruments.

APPLICATIONS WITH WIDE AREA 3D MEASUREMENT:

Medical devices, electronic components and assemblies, quality control, mechanical parts, machined parts, injected parts and multi-material parts.

Measurements:

  • Dimensions (distances, heights, widths) on parts up to 200mm x 100mm (height resolution <1µm, width repeatability 1µm)
  • Flatness
  • Angles
  • Curvatures
  • Profile slices
