摘要： A method of optimising the focus of a fibre laser is described, which comprises positioning the output of a fibre laser relative to a workpiece; measuring at least a portion of back reflected radiation from the workpiece (step 52); determining an integral of this; changing the relative position of the output and the workpiece one or more times (step 54,56), each time determining an integral of values for the back-reflection, and using the integrals to determine optimum focus.

摘要： A termination for an optical fibre is disclosed, including an end cap optically connected to a delivery end of the fibre and tapering its towards its proximal end so as to expand the signal beam output by the fibre, a capillary having a bore mounted so that the end cap and an end portion of the delivery fibre are mounted within the bore, the capillary having an end which is angled so as to reflect undesired radiation within the capillary away from the fibre, and a cladding mode stripper arranged upstream of the delivery end.

摘要： Spindle speed probes (6) and spindles including such speed probes. The speed probe (6) is arranged to sense the speed of rotation of a shaft (5) making use of a magneto resistive sensor (3). The magneto resistive sensor (3) is arranged in a stack with a circuit board substrate (62), an electronics module (61) and a permanent magnet (2). An additional magnet (8) may be provided to provide additional drag to help prevent undesirable windmilling.

摘要： A gas bearing assembly for a gas bearing spindle. The assembly comprises a housing portion (11) and an inner radial bearing portion (10) disposed within and resiliently mounted relative to the housing portion. The inner radial bearing portion comprises an inner shell bearing portion (12) having a bearing face, and an intermediate sleeve portion (14) which is disposed between the inner shell bearing portion and the housing portion. A liquid coolant channel (7) is provided between the inner bearing shell portion (12) and the intermediate sleeve portion (14). The assembly further comprises an anti-rotation plug (601, 901) which is received in both the housing portion (11) and the inner bearing portion (10) to couple the housing portion and the inner bearing portion against relative rotation.
