    摘要: A projection exposure apparatus is equipped with an illumination system, a reticle, a projection objective and an image plane. Interstitial spaces between the individual elements of the apparatus are open to the ambient space. A gas purge device which carries a stream of noble gas or nitrogen is arranged in at least one of the interstitial spaces. The gas purge device is of a shape and size so that one or more interstitial spaces are at least to a large extent sealed off from the ambient space surrounding the projection apparatus.

    摘要: 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).
