    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 method of determining any offset between: a scale axis of a disc scale member having a planar surface on which is provided a series of scale features defining a scale that extends and is centred around the scale axis, the scale axis extending normal to the planar surface; and the axis of rotation of a machine part on which the disc scale member is mounted, wherein the axis of rotation and the scale axis of the disc scale member are substantially parallel. The method includes: determining any offset between the scale axis and the axis of rotation via inspection of an axially-extending surface provided with the disc scale member.

    Abstract: A method of forming an encoder scale for a measurement device is disclosed. The method comprises taking a laser and a substrate carrying an etch-resistant film. Parts of the etch-resistant film are removed by use of the laser, thereby forming a pattern on the substrate that defines an encoder scale, and the substrate is etched through the parts of the etch-resistant film that have been removed by the laser.

    Abstract: A method of mounting a rotary scale member on a part, the rotary scale member including a body on which a series of position features defining a scale is provided, and at least one mounting flexure configured to engage the part, the method including: force-fitting the rotary scale member and the part together, whereby the at least one flexure is displaced by the part and thereby urged via a radial reaction force into engagement with the part so as to form a friction fit with the part such that the body of the rotary scale member self-locates at an initial default radial location with respect to the part; and tweaking the radial location of the body relative to the part away from its initial default radial location to a new radial location.

    Abstract: A sealed encoder module for mounting onto a machine so as to measure relative displacement of first and second parts of the machine. The sealed encoder module can comprise, a scale, a readhead comprising a scale signal receiver, and an integral protective housing which encapsulates at least the scale and said scale signal receiver. The sealed encoder module can be configured to determine and output diagnostic information regarding a scale signal detected by the readhead.

    Abstract: An encoder apparatus comprising a scale and a readhead assembly comprising a scale signal receiver. The scale and the scale signal receiver are located within a protective housing which is configured to protect them from contamination located outside the protective housing and comprises a seal through which the scale signal receiver can be connected to a part outside the protective housing. The arrangement of the scale signal receiver inside the protective housing is independent of the scale and protective housing.
