A torsional hinged mirror design with reduced flexing. In addition to a central spine to prevent or reduce flexing of the tips, the mirror layer also includes perimeter ridges to reduce or prevent flexing or warping of the mirror edges. To provide an even stiffer mirror with minimum weight, either or both of the hinge plate and balancing plate may also include perimeter ridges that align with the perimeter ridges of the mirror layer.
