The white light interferometer is a high-resolution texture measuring device. The measurements are based on the principle of interference of the broadband white light. This enables high-resolution non-contact texture measurements.


  • Surface analysis
  • Determination of roughness parameters
  • Influence of roughness characteristics on skid resistance
