A torsional hinged mirror design with reduced flexing. In addition to a central spine 46 to prevent or reduce flexing of the tips 62a, 62b, the mirror layer also includes perimeter ridges 70a, 70b, 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 44 and balancing plate may also include perimeter ridges that align with the perimeter ridges of the mirror layer. |
