Abstract
In a vacuum system comprising an evacuatable housing, an object holder and an object carrier which is detachably coupled thereto, the object carrier in one form is constructed to rotate about one axis relative to the housing or in a second form rotates about an orthogonal axis and which forms are interchangeable. A supporting element of the object carrier is driven by a push member or by a piezo-electric element in different embodiments. The object carrier is introduced through a lock in a side wall of the vacuum system and can be coupled to and uncoupled from the object holder by means of a special tool.
