Patent ID: 7843620

Claim:
A micromirror system comprising: a substrate wafer; at least one torsion spring; and at least two micromirrors, each being suspended on the substrate wafer via the at least one torsion spring, axes of rotation of the micromirrors being situated substantially perpendicular to each other to permit deflection of an optical beam in two directions substantially perpendicular to each other, wherein the micromirrors and the at least one torsion spring are patterned out of the substrate wafer, and lie substantially in one plane, wherein a hermetically sealed volume of a wafer in which the micromirrors and the reflecting mirror are situated is filled with a gas medium, under a predetermined pressure, in order to damp the mirrors, the gas medium being a protective gas, and wherein for a predetermined damping of the micromirrors, a structure of the micromirrors is offset with respect to an opposite structure of the substrate wafer, the two structures partially overlapping.
