Double-Beam Interferometer:


Double-Beam Interferometer:

Two parallel measuring beams are used to acquire two length values independently of each other. So it is possible to determine the position, angle and difference values simultaneously.


  • Simultaneous length and angle measurement or differential measurement
  • Beam distance selectable
  • Combinable with plane mirror, cat-eye or hollow reflector

Technical Data:


  • Measurement range: up to 2 m with plane mirror
  • Angle resolution: 0.001 to 0.005 arcsec (depending on selected beam separation)
  • Angle measurement with cat-eye reflector: up to ±5°
  • Data Sheet
