  • Arrangement of micromechanical elements
    Patent number: 8254005
    Abstract: The invention relates to arrangements of micromechanical elements, preferably microoptical elements, which are each held by means of spring elements. In this respect, they can be pivoted or also deflected in translation around a rotational axis by the effect of electrostatic forces. It is the object of the invention to provide an arrangement having micromechanical elements which can be operated over a long time period without drift without any frequent recalibration being necessary. The arrangement in accordance with the invention having micromechanical elements is made in this connection such that electrodes are likewise arranged beneath micromechanical elements, that is, on the side onto which no electromagnetic radiation can be directly incident. In this respect, a respective electrode is arranged and made such that it is associated with at least two micromechanical elements. It can in this connection effect a deflection of the micromechanical elements associated with it by electrostatic force effect.
