SP600 range

SP600 family of analogue scanning probes

  • SP600MHigh speed scanning up to 300 mm/s (11.81 in/s), fast point measurement and high frequency response
  • Three variants; SP600, SP600M and SP600Q allows the ideal probe match to suit the CMM
  • Measurement range of +/-1 mm in X, Y and Z
  • Stylus lengths up to 300 mm (11.81 in)
  • Low probing forces give maximum application flexibility
  • Extremely robust design will withstand moderate collisions
  • Fast and repeatable stylus changing enables the best solution for the application to be chosen and increases productivity - automatic changing with either SCR600 or SCP600 mounted on MRS / MRS2
  • Compatible with Renishaw's autochange rack systems (ACR1 or ACR3) to enable changing between other Renishaw autojointed probes
  • Excellent product life with an MTBF in excess of 50,000 hours gives low cost of ownership


Shank or clutch adaptor mounted probe.


  • Autojoint mounted probe
  • PH10M PLUS / PH10MQ PLUS compatible
  • Automatically interchanged between other autojointed probes using ACR1 or ACR3
  • (When used on PH10MQ PLUS, a PEM25 extension bar is required to acheive all B-axis positions for A-axis greater than 90°)


  • Direct in-quill mounted probe
  • Suited to machines with small working volumes

SH600 STD / SH600 EXT stylus holders

  • Provide overtravel protection and enable rapid and repeatable interchange between
    stylus configurations
  • Stylus changing can be automated by using the SCR600 stylus change rack or SCP600 stylus change ports mounted on an MRS / MRS2
  • SH600 STD can carry styli up to 200 mm (7.87 in) long
  • SH600 EXT can carry styli up to 300 mm (11.81 in) long

Principles of operation

  • SP600 mechanismMotion based on a system of parallel operating springs that support an arrangement of three light emitting diodes (LEDs)
  • The triangular shaped light-box is mounted on, and moves with the motion system - it contains three LEDs one for each axis
  • Light from the LEDs is focused into slits and shine onto three individual position sensitive detectors (PSDs) that are fixed to the body of the probe
  • Linearity specification of the PSDs used in the probe is better than 0.25%
  • The design gives an excellent self centring figure of <5 µm; a measure of its ability to return to zero mechanically when not in contact with the part
  • This low figure, although irrelevant to the probe's accuracy, enables the use of small deflections and therefore low contact forces
  • Probe output always gives its precise position relative to the probe body
  • Low mass, high structural stiffness and friction-free viscous damping give excellent dynamic performance characteristics
