Holding device for use in coordinates-measuring device, has supporting points for two-dimensional substrate such that supporting points carry two-dimensional substrate, where substrate is force-freely held with objects

摘要

The device (20) has supporting points (121) for a two-dimensional substrate (2) such that the supporting points carry the substrate, which is force-freely held with objects (3). A medium (125) e.g. mercury, is provided in a container (130) for force-free holding of the substrate. The container has an opening to receive the substrate. An intermediate element is formed as one-part intermediate element and arranged between the substrate and medium such that direct contact between the substrate and the medium is absent. The element has a membrane made of flexible material e.g. rubber.
