Confocal Sensor Systems for Displacement, Distance, Position and Thickness


Confocal chromatic sensors provide the latest modern technology for displacement, distance, position and thickness measurements combined with maximum precision and high speed. A large range of sensors and different controller interfaces open versatile fields of application, e.g. in the semiconductor industry, glass industry, medical engineering and plastics production.

Especially when measuring on reflecting and shiny targets, confocal chromatic sensors provide high accuracy whereas laser sensors are overdriven due to the high light intensity. This is a major advantage in a ‘live’ production process, where tactile measurement technology is operating at its limits, especially if the target is located in a difficult-to-access area.

  • Benefit from the advantages confocal sensors offer:
  • High measuring rate
  • Nanometre resolution
  • Almost surface-independent measurement, also valid for mirrored and glass surfaces
  • Extremely small and constant spot size
  • Ready for vacuum
  • Fastest controller worldwide with integrated light source
