Alignment adjusting device

An alignment adjusting device for an optical focal plane assembly, which is adapted to be integrated in the optical focal plane assembly having a detector with a detector plane and is adapted to be mounted to an optics assembly having an optical focal plane, the alignment adjusting device being adapted to allow an alignment of the detector plane representing an image area and the optical focal plane, the alignment adjusting device comprising:

• a detector support configured to receive the detector;
• a plurality of members, a first member of the plurality of the members being connected to the detector support and a second member of the plurality of the members being connected to a flange that is adapted to be connected to the optics assembly;
• wherein
• the first member, the second member and a remaining number of the members being pairwise moveably connected to each other by a number of springs and/or a number of supporting elements, the number of springs and/or the number of supporting elements being adapted to enable a relative translational movement along axes of a given coordinate system and/or a relative rotational movement around the axes of the given coordinate system between the detector plane and the optical focal plane, wherein
• the plurality of members comprise:
• an intermediate ring representing the second member being connected to the flange by way of detachable lock bolts;
• an outer frame being firmly connected to the intermediate ring and having a substantially cylindrical shape;
• an inner frame being coaxially arranged within the outer frame and having a substantially cylindrical shape extending parallel to the outer frame, the inner frame being connected to the outer frame by at least one adjusting device, which is oriented coaxially with the inner frame and outer frame;
• a first flexible joint connected to the inner frame;
• and
• a second flexible joint representing the first member.
