RSP3 REVO scanning probe
The RSP3 range of 3D scanning probes gives REVO-2 the ability to carry cranked stylus arrangements and enhanced capability for carrying long styli
RSP3
- The RSP3-1 / 2 / 3 / 4 probes can be used for both 3D-scanning (X, Y, Z) and touch-trigger applications
- They enable accurate scanning measurement with effective stylus lengths ranging from 20 mm - 394 mm
- The RSP3 range uses 3-axis scanning with fixed REVO-2 head angles during measurement
- RSH3 stylus holders are intended to fit only with their respective RSP3 probe
RSP3-6
- The RSP3-6 probe provides REVO-2 with enhanced capability for carrying long cranked and straight styli, and can be used for 2D scanning and 3D touch-trigger applications
- It carries straight extensions up to 800 mm from REVO-2's A-axis centre of rotation, and cranked extensions up to 600 mm from REVO-2's A-axis centre of rotation

Dimensions
NOTE: Dimensions in mm (in).
INFO: When RSH3-3 is used with a 25 mm long cranked stylus, the use of a 20 mm extension is recommended as it balances the spring rates (X, Y and Z) of the probe and results in better metrology.
Design principles of the RSP3 scanning probes
RSP3 uses an optical transducer sensor and a pivoting motion system similar to that found in SP25M system.
The probe's pivoting motion system has two diaphragm springs. One of the RSP3 springs allows movement in all directions whilst the other (pivot) spring is stiff in (probe) X and Y, but allows movement in Z. Its optical transducer sensor system has two infrared light emitting diodes that project invisible infrared beams on mirrors mounted on the pivoting moving structure within the probe. The mirrors focus the beams back onto two position sensitive devices (PSDs) which provide signal outputs in the three probe axes: p,q,r (converted into X, Y, Z signals by the calibration routine).
Unlike the SP25M, the RSP3's probe and module elements are built as one.

RSP3-# changing system
The RCP TC-2 (thermally controlled REVO-2 change port) is used for changing RSP3-1 / 2 / 3 / 4. RCP TC-3 is used for changing RSP3-6. The FCR25 (flexible change rack) is configured to change SH25-# or the newer RSH3-# stylus holders. RSH3-6# stylus holders should be changed using RCP2.
RSP3-1 / 2 / 3 / 4
NOTE: Please observe the orientation of the probe in the RCP TC-2.
The stylus tool is used to keep the port lid open during calibration. It must be removed for normal operation.
