SP80 / SP80H scanning probe system

SP80 and SP80H quill-mounted scanning probes

  • SP80 scanning probeUltra-high accuracy measurement, provided by digital scale and readheads - system resolution of 0.02 µm (79 µin)
  • Long stylus carrying capability for access to deep features - up to 1000 mm (39.4 in) and 500 g (17.64 oz) mass on SP80
  • Unbalanced stylus configurations do not require counterbalancing
  • SP80H variant mounts to horizontal quill - styli up to 500 mm (7.87 in) long and 500 g (17.64 oz) mass
  • Isolated optical metrology for direct accurate measurement of stylus deflection
  • Low inertia mechanism for excellent dynamic response
  • Passive scanning probe with no motors, giving improved thermal stability and reliability
  • Bump-stop crash protection in the Z-axis, together with a detachable stylus holder for XY crash protection
  • Adaptor plates enable rapid interchange between SP80 and PH10MQ PLUS motorised head
  • Kinematic stylus changing for repeatable relocation of the optimum stylus configuration - removes the need for requalification

Isolated optical metrology system

SP80 - cut away
  • Readheads for each axis are fitted to the body of the probe
  • Light is reflected from the moving cube onto the readhead
  • System measures deflection of the whole mechanism
  • Detects sources of variable error such as thermal and dynamic effects
  • Any inter-axis error caused by arc motion of parallel acting springs is directly measured by the sensor system
  • System has no moving wire connections

† Probes with displacement sensors mounted to stacked axes suffer from latency under changing inertial loads and cannot detect thermal growth in their mechanisms.

SP80H specification

Stylus carrying capability

Due to the different orientation of the kinematics problems can occur when trying to support heavy styli on SP80H. Failure to reseat properly after the kinematics have been reseated may be observed with styli that have a moment at the stylus root greater than 200 g at 200 mm.

A graph representing a safe working moment range is shown below; this is based upon stylus weight and centre of gravity (COG) distance from the stylus root. It is advised that where possible customers should try and use styli configurations for SP80H that fall within these guidelines.
