摘要： The invention provides a method and apparatus for adjusting the direction of a beam of radiation 13 in which a mirror 19 is mounted on a shaft 1 so that the normal to the mirror is inclined relative to the longitudinal axis 11 of the shaft, the shaft being mounted in a bearing 2,3 for rotational adjustment relative to a supporting structure 20, 21. The invention may, for example be applied to monochromators or interferometers in which radiation beams must be adjusted in direction to very close tolerances, typically seconds of arc, and maintained in direction with a corresponding stability. In accordance with the invention the shaft is rigidly secured in the bearing after adjustment by means of an adhesive. A stress-free structure is realised in which hysteresis effects due to temperature cycling are minimised.

摘要： Rigid supporting structures for the components of high precision optical instruments, such as interferometers or monochromators, have hitherto been based on massive castings. Such castings suffer from residual non-recoverable changes of shape during temperature cycling, due to the differential temperatures set up in the castings. The invention provides a rigid structure assembled from a number of flat sheet structural elements 51,52,57,64. Each sheet element is substantially rigid in its own plane and is attached to one or more other sheets at points of contact which are such that the edge of one sheet bears against the surface of another sheet, the planes of the two sheets being perpendicular in the region of the points of contact. An open ended rectangular box structure 50 may be assembled from two sheets 51,52, each with a single right angled fold. Each point of contact and attachment may be formed as a foot 53,54,55,56,58,59,77,62,63,80 standing proud from the remainder of the sheet edge.

摘要： In beam splitting interferometers for use in Fourier transform spectrometers working in the infra-red region from 2.5 microns to 50 microns wavelength, it is impossible to provide a single beam splitting assembly which is efficient over the whole wavelength range, due to the limitations of available materials. In a set of interchangeable beam splitters it Is difficult to ensure sufficiently accurate registration of each beam splitter after a change. The invention provides a set of beam splitters 4,5 held stationary in separated locations and radiation directing means 2, 3, 26, 28 which passes an input beam 12,13 through a beam splitter, which selects the recombined beam 23 or 24 emerging from a desired beam splitter, and which passes it to a detector 25 in a fixed location.
