Renishaw's range of scanning probes are all passive
sensors, featuring lightweight mechanisms and
optical metrology systems for fast and accurate
Scanning probes are miniature measuring machines that
can acquire several hundred surface points each second.
Your CMM software can use this data to provide you with
information about the form of the features that you
measure, as well as their size and position. Scanning
probes can also be used to acquire discrete points in a
similar way to touch-trigger probes.
Renishaw scanning probes feature innovative, lightweight
passive mechanisms (no motors or locking mechanisms)
that exhibit a high natural frequency, making them
suitable for high speed scanning. Isolated optical
metrology systems measure the deflection of the stylus
directly (not via stacked axes within the probe
mechanism) for better accuracy and faster dynamic
response. A range of solutions are available, suitable
for all sizes and configurations of CMM.
SP25M scanning probe system
At just 25 mm diameter, and with a range of
scanning and touch-trigger modules, the SP25M is the
world's most compact and versatile scanning probe
system.The SP25M's compact size and Autojoint
mounting makes it compatible with the PH10M/MQ, PH6M
and PHS1 probe heads. It can also be mounted on a
multiwired extension bar. Together, these
combinations permit excellent reach and access to
The SP25M is actually two sensors in one! Users can
switch between a choice of three scanning modules
(which can carry M3 styli with lengths from 20 - 200
mm) and an adaptor module that is compatible with
Renishaw's TP20 range of probe modules. This
capability enables scanning and touch-trigger
probing in a single probe system.
SP80 ultra-high accuracy scanning probe
The SP80 quill-mounted scanning probe
provides class-leading scanning performance, as well
as the most flexible use of styli for maximum
The SP80 is a passive scanning probe that uses
digital scale and readheads with 20 nm resolution.
These provide exceptional scanning performance, even
with long styli.
The SP80 can carry styli up to 500 mm long and 500 g
mass, including star configurations. Unbalanced star
configurations do not require counterbalancing.
Kinematic stylus changing allows for repeatable
re-location of the stylus, optimises stylus
arrangements for each feature, and overcomes the
need for re-qualification.
The SP80 has a kinematic mount that offers a
repeatable connection to the mating plate mounted on
the quill (KM80), allowing the probe to be easily
SP600 scanning probes
Renishaw's SP600 family of analogue
scanning probes offers high-performance inspection,
digitising and profile scanning capability for a
wide range of CMMs.
Renishaw have three, highly versatile, SP600
scanning probe systems to choose from (SP600, SP600M
& SP600Q) to suit a wide range of CMMs. A system
includes the probe itself, a PC interface card and a
stylus module changing rack. Together, these offer
great user flexibility and the capability to meet
most of the demands of today's CMMs.
SP600 probes enable rapid collection of large
amounts of measurement data during inspection,
digitising or profile scanning and are suitable for
a wide range of applications such as gear
inspection, sheet metal profile measurement, form
measurement, and fine detail scanning.
