ABSTRACT:
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.
