RLD10 no internal interferometer

Combining the ease and performance of Renishaw's unique fibre optic delivery system with application specific optical configurations.

Containing a unique multi-channel fringe detection system, laser shutter and integrated beam steerer allows the RLD to be easily introduced into specialist applications.

The RLD10-XX head is only available as a 0° variant.

Features and benefits

  • Custom optical solutions - containing no internal optics allows for the RLD to be configured for external optics to cover a range of applications.
  • Calibration measurements - suitable for use with the Renishaw calibration optics range allowing for straightness, angular and linear measurements.
  • Vacuum compatible - also compatible with the RVI20 for relative measurements between two features.
