Abstract: In a temperature compensation apparatus for thermally loaded bodies made from materials of low specific thermal conductivity, a heat-distributing device having one or more heat-distributing bodies is adapted to surfaces of the thermally loaded body such that there remains between the thermally loaded body and the heat-distributing bodies a gap which is filled with a fluid for the purpose of the thermal coupling of thermally loaded bodies and heat-distributing bodies in conjunction with mechanical decoupling.

Abstract: A mounting device for an optical element in an assembly has a support member 3 with two or more gear elements 1. The support member 3 is connected, on the one hand, to an external mounting structure 30 and, via base points 2, to the gear elements 1. Via top points, the gear elements 1 are connected to the optical element 5 directly, or are connected to the optical element 5 indirectly via a mount 5′ arranged therebetween. The top points 4 of the gear elements 1 are located in planes of symmetry of the optical element 5 which are defined by the axial axis and a radial axis of the optical element 5. The gear elements 1 are arranged and dimensioned such that in the event of disturbing influences a compensation effect is produced with regard to the deformation of the optical surface of the optical element 5.
