SH25 stylus holder range metrology performance
SH25-2A, SH25-3A and SH25-4A have distinct metrology advantages over SH25-2, SH25-3 and SH25-4 for any stylus arrangements
where the stylus holder is subjected to torsional load when using components like cranked styli or knuckle joints.
The standard range of SH25 stylus holders still have an advantage over the -A range of stylus holders when straight styli arrangements are
required.
The following tables compare typical metrology performance with the standard and -A range of SH25 stylus holders for both straight and
cranked stylus configurations.
