  Application note: Mirror selection for optical periscopes

  Renishaw differential interferometer detector head (RLD10-X3-DI) is sometimes required to work with larger beam separation between the measurement and reference beams. For these applications, Renishaw recommends the use of a periscope style assembly; however the specification of the mirrors within this assembly are critical and this application note highlights the reasons behind this.

• Application note: High resolution compensated positioning
  

  Application note: High resolution compensated positioning

  The RCU10 provides real-time compensation for the effects of air refractive index changes and material temperature changes on the position reading given by a laser encoder system. It can also compensate for the effects of material expansion on a linear (tape or glass) encoder.
