Adjustable mounting arrangement for an object to be positioned precisely relative to a base

Abstract

An adjustable mounting arrangement to position an object of an optical reflecting telescope relative to a base includes at least two support structures connected to the base and to the object. Each of the at least two support structures has two four-link beams arranged nonparallel to each other and a cradle having two connecting links. Each of the two four-link beams has a first strut and a second strut running nonparallel to each other, where each of the first and second struts have a first end and a second end, respectively, and where each of the first and second struts is mounted with articulation via their respective first end in a corresponding inner joint on the object. The first strut and the second struts are equipped on each of their second ends with a corresponding outer joint, where the outer joints of the two four-link beams are connected to each other via the connecting links such that a distance between the outer joints is less than a distance between the inner joints, and a first and a second joint axis of each four-link beam lie in or at an angle to a plane defined by a corresponding one of the two four-link beams. A third and a fourth joint axis of each four-link beam lie in the plane is defined by a corresponding one of the two four-link beams. Each of the at least two support structures forms a three-dimensional multi-articulated structure comprising the two four-link beams coupled to each other, and each of the two four-link beams is offset to an inner side in relation to a straight line connecting the outer joints, where each of the connecting links is configured with a bearing surface of a support bearing. Finally, each of the at least two support structures is mounted with articulation relative to the base by the support bearing.
