Lagerung für einen astronomischen Spiegel

摘要

A mounting for an astronomic mirror (41) has several mounting elements (48, 49; 50, 51) arranged underneath the bottom side of the mirror. The lines of application of the mounting elements run through the general centre of gravity of the mirror and the mirror (41) is secured against rotation and axial lateral displacements. At least three dimensionally stable auxiliary structures (44, 45) without thermal deformation in the plane (52) of the centre of gravity are arranged between the mirror and the mirror mounting elements. The auxiliary structures are directly secured to the mirror (41) to be supported and three actuators (48, 49; 50, 51) are arranged between the mirror mounting elements and each auxiliary structure.
