Patent ID: 7589884

Claim:
A Micromirror Array Lens having a plurality of micromirrors, wherein each micromirror in optically effective area comprising: a) a substrate with at least one electrode to provide actuation force for micromirror motion; b) at least one actuation element to make micromirror motion controlled by electrostatic force induced by the electrodes in the substrate; c) a micromirror structure having rotational and/or translational motions controlled by the actuation elements; d) a sub coating layer; e) an over coating layer; and f) an totally encapsulated metal layer by the sub coating layer and the over coating layer to make the micromirror structure have high reflectivity; wherein the effective area is where focusing of the Micromirror Array Lens occurs and wherein the metal layer is encapsulated by the sub coating layer and the over coating layer to prevent the metal layer from oxidation and to prevent the micromirror structure and the actuation elements from galvanic corrosion.
