Optical encoders

Optical encoders

Renishaw, a world leading metrology company, has a 50% share holding in associate company RLS. Over more than 15 years, both companies have  successfully worked together on research projects, joint market strategies and other initiatives aimed at providing our customers with exceptional products and services.

 

Renishaw optical encoders offer robust and high-performance linear and rotary position measurement using a finely graduated scale and a compact optoelectronic readhead that converts motion relative to the scale into position data.

 

  • Incremental and absolute position measurement available
  • Non-contact design - zero hysteresis and no mechanical wear
  • Robust optical design - high immunity to dirt, dust and scratches without compromising signal integrity
  • Linear scales are used where straight-line position information is needed - usually X, Y or Z axes.
  • Incremental encoders are used in applications where instant and accurate relative position is needed, in either analogue or digital format.
  • Ultra-High Vacuum (UHV) encoders are optimised for use in vacuum environments.
