Claim:
1. A Micro Electro Mechanical Systems (“MEMS”) micromirror including, a frame, a mirror body arranged therein, said mirror body having a mirror support and at least one attachment portion, wherein a mirror is formed on the mirror support or attached to the mirror support, wherein a face of the mirror defines a mirror plane of the mirror support, said mirror body being rotatable around a rotation axis extending in a plane (X-Y) defined by the frame, at least one cantilever beam assembly having a torsional stiffness and a longitudinal direction and extending within said plane, and vertical support beams having a torsional stiffness connected between the mirror body and the frame along the rotation axis, the at least one cantilever beam assembly having a cantilever beam with a first and a second end and a relief means at the first end configured to enable a translation of the cantilever beam at its first end in said longitudinal direction, with the first end being coupled via the relief means to the frame and the second end being fixed to said at least one attachment portion of the mirror body, each attachment portion forming a rigid connection between said second end of the at least one cantilever beam and the mirror support, and wherein the cantilever beam has a thickness, perpendicular to a plane of the frame, that is smaller than its width, in the plane of the frame, wherein the torsional stiffness of the vertical support beams about the rotation axis is smaller than the torsional stiffness about the rotation axis provided by the at least one cantilever beam assembly.
