ABSTRACT:
A device for holding measurement instruments (2), in particular interferometers, is formed from a plurality of structure elements (4, 5, 6, 7) connected to one another and made from at least one material. The at least one material has a very low coefficient of thermal expansion α. The structure elements (4) on which the measurement instruments (2) are arranged are secured between at least two structure side parts (5) in such a way that the thermal expansions of the structure side parts (5) and of the connections (3) have no effect in the measurement direction of the measurement instruments (2).
