Laser Interferometer:

Single-beam, high precision interferometer with plane-mirror, ball or hollow reflector. Single laser beam with the same optical path for the reflected measuring beam.

 

 

Benefits
  • Best linearity

  • Measurement also through small windows
  • In case of using plane mirrors a lateral movement of the mirror or of the interferometer orthogonal to the measuring axis is possible
  • In case of using ball or hollow reflectors with high tilting invariance, the adjustment of the interferometer is very easy. The measuring distance is increased compared to the mirror reflector

 

Applications
  • Calibration of length measuring instruments, multiple coordinate, measurements, e.g. on planar tables, eccentricity and concentricity measurements

Benefits
  • Flexible, ultra-precise length measuring system
  • Modern industrial design, protection against splash water
  • Single-beam measuring principle minimizes Abbe errors
  • Plane mirrors and tilt-invariant reflectors are possible
  • Compact system for on-site use possible

 

Applications
  • Precision laser interferometric length measuring system as a measuring or calibration instrument for measuring and positioning stages, microscope stages, measuring machines, machine tools, hardness and materials testing instruments

  • Multiple coordinate measurements, e.g. on planar tables
  • Calibration of length measuring instruments
  • Eccentricity and concentricity measurements
  • Non-contact surface measurements

 

Model SP 15000 NG

Benefits
  • High precision length measurements over long distances
  • Large tilt invariance
