Abstract: An analogue probe for a machine tool apparatus, including a probe body and a stylus member movably secured to the probe body in a suspended rest position via a suspension mechanism. A sensor is provided for measuring the extent of displacement of the stylus member relative to the probe body from a rest position. The analogue probe further includes a first compliant sealing member extending between the probe body and stylus member such that the sensor is contained within a chamber sealed from external contaminants. The analogue probe also has for a suppressor for suppressing movement of the stylus member away from its suspended rest position induced by changes in the chamber's internal pressure and/or changes in the analogue probe's operating environment.

Abstract: An analogue probe for a machine tool apparatus, which includes a probe body, a stylus member movably secured to the probe body and a sensor that measures the extent of displacement of the stylus member relative to the probe body, in which the sensor is contained within a chamber in the probe body. The analogue probe further includes a vent between the chamber and the outside of the probe body, configured such that, when the vent is open, the pressure within the chamber can equalise with the analogue probe's operating environment's pressure, and is further configured such that the vent's opening to the outside of the probe body can be closed so as to seal the chamber and the sensor from external contaminants during operation of the analogue probe.

Abstract: A method and apparatus is disclosed for producing precision marks for a metrological scale in the form of a stainless steel ribbon. A laser is used to produce ultra-short pulses which have a fluence at the ribbon such that ablation takes place. The laser light can be scanned via scanner and the pitch of the marks can be controlled. The ablative technique causes little thermal input and improves the accuracy of the scale.

Abstract: A tool setting or tool analysis device for a machine tool comprises a light source for producing a light beam. A light receiver receives the light beam and produces a signal indicative of the amount of light received. This is analyzed by a main analysis circuit to generate a trigger signal to a machine controller when the beam is at least partially occluded. To provide fail-safe operation should the main circuit not recognize the tool, a back-up trigger signal is produced after a delay by a delay circuit. In one preferred form, the back-up trigger signal may oscillate, providing repeated edges which can ensure fail-safe operation even if the machine controller suffers from a blind window and therefore misses the initial trigger signal.

Abstract: A Raman spectroscopy system has a filter arrangement comprising two filters (16, 26A) in series, to reject light of the illuminating wavenumber from the scattered light of interest. The filters are tilted and have different characteristics for light of first and second different polarisation states. To counter this, the filters are arranged so that their respective effects on the respective polarisation states at least partially cancel each other out. This may for example be done by arranging their tilt axes (32, 34) orthogonally to each other.

Abstract: Measurement apparatus is described that comprises a measurement portion for acquiring object measurements and an output portion for outputting measurement data relating to the acquired object measurements. A deactivation portion is provided for inhibiting normal operation of the measurement apparatus such that output of the measurement data is prevented. The deactivation portion, in use, reads apparatus usage information from an apparatus usage module and inhibits normal operation of the measurement apparatus if said apparatus usage information fails to meet one or more predetermined criteria. The apparatus usage module may be provided as an integral part of the measurement apparatus or as a separate activation button. The measurement apparatus may comprise a measurement probe such as a touch trigger measurement probe.
