Apparatus with an optical bench and at least one optical element, which is attached on the optical bench, whereby the optical bench comprises a layer structure with an extruded honeycomb plate from light alloy, paper or char-fiber-reinforced plastic. A first cover layer is glued to the honeycomb plate and comprises a first glass-like plate, which is surface-treated on that side which faces away from the honeycomb plate. A second cover layer glued to the lower surface of the light alloy honeycomb plate and comprises a second glass-like plate. The optical bench has suspensions, which glued to one or more parts of the layer structure for force introduction into the layer structure. The optical element is fixed by cold welding or glueing on the surface-treated side of the first glass-like plate.

The invention claimed is: 1. Apparatus with an optical bench and at least one optical element which is attached to the optical bench, whereby the optical bench comprises a layered structure, with an extruded honeycomb plate formed from light metal, paper or carbon reinforced plastic with an upper and a lower side, the honeycomb plate defining a cutout for receiving a suspension therein, a first cover layer being glued to the upper side of the honeycomb plate and comprising a first glass-type plate including a treated surface on the one side that faces away from the honeycomb plate, a second cover layer being glued to the lower side of the honeycomb plate and comprising a second glass-type plate, a suspension disposed in said cutout and glued to one or more parts of the layered structure for guiding forces, and the optical element being attached to the surface-treated side of the first glass-type plate by means of optical contacting or glueing. 2. Apparatus according to claim 1, characterized in that the first glass-type plate and/or the second glass-type plate comprises glass or a glass-ceramic, preferably Zerodur, UVM, or a guartz glass. 3. Apparatus according to claim 1, characterized in that the honeycomb plate comprises aluminum, paper or CFK, whereby the walls of the honeycomb plate have holes, preferably in the form of perforations. 4. Apparatus according to claim 1, characterized in that the first cover layer comprises an intermediate layer in addition to the first glass-type plate, which is situated between the honeycomb plate and the first glass-type plate and which preferably comprises a fiber enforced material. 5. Apparatus according to claim 1, characterized in that the treated surface of the first glass-type plate includes a polished surface providing an optically functional surface for attaching the optical element. 6. Apparatus according to claim 1, characterized in that the suspensions are realized and arranged so that the guiding of forces into the layered structure takes place at least at three locations at the circumferential area of the layered structure. 7. Apparatus according to claim 1, characterized in that the suspensions are glued by a glue film into the layered structure so that the glueing connections between the suspensions and the layered structure are mainly subjected to tension and/or shear. 8. Apparatus according to claim 1, characterized in that the first glass-type plate consists of the same material as the optical element. 9. Apparatus according to claim 1, characterized in that a glue film is applied for the glueing of the cover layers which preferably hardens with temperature. 10. Apparatus according to claim 9 characterized in that the glue film is an epoxy glue film. 11. An apparatus according to claim 1 for use in a satellite, further including a 3-point suspension. 12. Apparatus according to claim 11, characterized in that the 3-point suspension comprises bipods. 13. Apparatus according to claim 1 characterized in that the second glass type plate is also surface treated on the side facing away from the honeycomb plate.
