SP600 scanning probe range

• High 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

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

• Motion 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
