Abstract
There is disclosed an adjustment structure for use in initially aligning the two arms of an interferometer, by varying slightly the angular position of mirror surfaces. Two 'wedge' elements are used behind the mirror, each of which is independently rotatable about an axis perpendicular to the face of the mirror. In order to provide ideal lubrication between the relatively movable flat engaging surfaces, a solid layer of a low friction polymer is used, preferably polytetrafluoroethylene.
