  • www.CMMXYZ.comwww.CMMXYZ.com SP25M designed for “isolated optical metrology” • IREDs in probe body reflect light off mirrors in scanning module back onto PSDs • high integrity performance – motion is faithfully translated to PSD’s • non-linear outputs are compensated by sophisticated 3rd order polynomial algorithms • no moving wires Design characteristics and performance 2 PSDs (in body) detect stylus deflection 2 Mirrors (in scan module) reflect beams back to PSD’s Kinematic joint line between probe body and scanning module 2 IRED sources (in body) IRED beams Body Module
  • www.CMMXYZ.comwww.CMMXYZ.com Why are there 5 scan modules to cover the stylus range? Traditionally, increasing stylus length leads to reducing accuracy SP25M addresses this characteristic … • scan modules designed for optimum output from PSD sensors when using shortest stylus at max operating deflection (resulting in largest pivot motion/swept area over PSD’s by IRED beams - so giving best gain, resolution and highest accuracy metrology) whilst restricting loss of performance as longer stylus is used (by ensuring sufficient coverage of sensor is maintained resulting in low degradation of accuracy performance) • if excessive stylus length is used, the pivot motion angle rapidly reduces (resulting in less swept area over PSD’s and non optimised transducer performance giving reduced accuracy) 1. Design optimised such that max operating deflection results in highest performance of optical transducer 2. Swept area across PSD is optimised over specified stylus range 3. Reduced performance of sensor if longer stylus is used Specified stylus range Module lengths increase as spring gap changes to achieve desired pivot motion Design characteristics and performance
  • www.CMMXYZ.comwww.CMMXYZ.com Design characteristics and performance • the dedicated range for each stylus module also means that contact forces at the tip can be closely maintained (if we were to use excessive stylus lengths the force would reduce, reducing stability and accuracy) • the fixed extension design of SH25-2/3 prevents use of illegally short stylus • high accuracy data maintained as stylus length increases (see next slide) • unique design of SP25M can result in 2-3 times better accuracy than SP600 Module lengths increase as spring gap changes to achieve desired pivot motion Specified stylus range 4. Design optimised to maintain a nominal deflection force of 60 g/mm across all three modules 5. Possible unsatisfactory contact force if longer stylus is used
