µCMMOptical coordinate measuring machine to measure tight tolerances

Measurement of small surface details on large components with highest precision

µCMM, the first purely optical coordinate measuring machine, is used to measure extremely tight tolerances in high accuracy. Users combine advantages from tactile coordinate measuring technology and optical surface measuring technology: 

  • measurement of dimension, position, shape and roughness with only one sensor
  • high accuracy over the entire measurement volume
  • non-contact, optical measurement with Focus-Variation
  • suitable for matte to highly polished components
  • easy handling
  • wear-free, robust and suitable for production
