Optical metrology accessories

Our range of measurement optics enables you to measure linear displacement across a range of axes.

Linear optics

Linear optics kit

There are two types of linear optics kits available.  The standard Linear optics kit is suitable for axes up to 30 m (HS20 only).  The interferometer and retroreflector assemblies have been designed to be easily mounted to the HS20 alignment plate to the laser head end of the axis.

Kit contents

  • 1 linear interferometer
  • 2 linear retroreflectors and clamp screws
  • 2 alignment targets

Features and benefits

  • Easy alignment - using Renishaw's alignment targets simplifies the alignment process.
  • Anti-reflective coating - Renishaw's optics contain a high quality anti-reflective coating to achieve high levels of measurement performance.
  • Simple mounting - directly compatible mounting with the HS20 alignment plate results in a simple installation process.

Long range linear optics

Long range linear optics

The second linear optics kit available from Renishaw is a Long range linear optics kit suitable for axes up to 60 m (HS20 only).

The Long range linear optics kit includes an additional periscope and large retroreflector assembly.  These allow for an increase in the offset between the two beams as they travel along the machine axis.

Kit contents

  • 1 linear retroreflector and alignment target
  • 1 long range linear retroreflector and target
  • 1 linear interferometer
  • 1 long range periscope

Features and benefits

  • Easy alignment - using Renishaw's alignment targets simplifies the alignment process.
  • Anti-reflective coating - Renishaw's optics contain a high quality anti-reflective coating to achieve high levels of measurement performance.
  • Simple mounting - directly compatible mounting with the HS20 alignment plate results in a simple installation process.

LS06 laser beam steerer

LS06 beam steerer

The laser steering mechanism of the LS06 laser beam steerer is an alignment aid for the HS20 laser scale.  This device allows easy adjustment of both the pitch and yaw of the laser beam.

The LS06 laser beam steerer mounts onto the front of the interferometer optic and is compatible with both standard and long range linear optics kits.

Features and benefits

  • Beam adjustment - the LS06 laser beam steerer provides an independent 0.6 mrads pitch and yaw angular adjustment.
  • Fast alignment - using the two levels to adjust the pitch and yaw allows for a quick alignment process.
  • Standard mounting - directly compatible with Renishaw's interferometer assemblies allowing the beam steerer to be easily mounted.
