High-precision Surface Inspection

waveCHECK is a handheld-portable 3D-inspection tool for inspecting wind turbine blades in manufacturing and operation. Its efficient detection of surface defects and instant visual feedback revolutionize surface inspection.

  • Waves and Wrinkles
  • Steps between core material panels and/or pre-fabricated components
  • Gaps between core material panels during lay-up
  • Flaws in paint/top coat
  • Chamfers, e.g. of bond line edges
  • Rain Erosion
  • Any other surface damage that is reflected in the surface topology/topography


ISO 17025

  • Gold standard for calibration
  • Consistent precision of measurement results
  • Traceable to national reference standards

Surface analysis with zero post-processing

waveCHECK’s powerful detection and instant analysis revolutionize blade inspection. The user-centric design allows for quick deployment in existing workflows: 1-Button Operation, zero Post-Processing.
