SIOS GmbH Differential interferometer

There are two differential interferometer configurations available from SIOS GmbH, ie with external reference arms. (the SP-D has two measuring arms and internal reference arms)

SP-DI

SIOS Differential interferometer SP_DI

Symmetrical construction for high precision measurements using a differential interferometer
  • High stability
  • Identical optical paths - ie reference and measuring arms pass through the same optical path.
  • Beam separation  ~20mm
  • Resolution  <0.1 nm
  • The result of measurements is a difference between displacements measured by each beam
  • A number of mounting options

For more information please download the SP-DI brochure

 

 

SP-DIS

SIOS Differential interferometer SP_DIS

Measurements with external reference object using a differential interferometer

Measurement result is not affected by the position of interferometer, (for dissimilar reference and measurement paths)

Application
• Calibration of the mirrors
