Laser Calibration Interferometer SP 15000 C5 with compact straightness measurement

Laser Calibration Interferometer SP 15000 C5 with compact straightness measurement

  • Due to the compact arrangement, the straightness measurement is considerably simplified.
  • Only two components (sensor head with straightness mirror and reflector unit) have to be aligned with each other.

Technical Data:

Length measurement

  • Measuring range: 15 m (up to  50 m)
  • Length resolution: 20 pm
  • Beam distance: 50 mm

Angle measurement

  • Measuring range: up to ±5°
  • Angular resolution: < 0.01 arcsec (up to 0.0004 arcsec)

Straightness measurement

  • Measuring range: ±4 mm
  • Resolution: 10 nm
  • Axial range (in measuring range freely selectable): < 6.5 m

Applications:

  • Calibration of high-precision axes in measuring and machine tools, as well as coordinate measuring instruments
  • Laserinterferometric measurements on guides and translation stages
  • Ultraprecise simultaneous length and angle measurements
  • Differential measurements
