A micro-electro-mechanical (MEM] optical device having a reduced footprint for increasing yield on a substrate. The MEM device includes an optical element having an outer edge and supported by a support structure disposed on a substrate. The support structure is mechanically connected to the substrate through first and second pairs of beams which move the structure to an active position for elevating the optic device above the substrate. When in an elevated position, the optical device can be selectively tilted for deflecting optic signals. The beams are connected at one end to the support structure, at the other end to the substrate and are disposed so that the first and second beam ends are located proximate the optical device outer edge. In a preferred embodiment, a stiction force reducing element is included on the outer edge of the optical device for reducing the contact area between the optic device edge and the substrate.
