<p>The device has a control unit (4) controlling a length of a controllable length element e.g. beam (2), where the element is connected to an optical surface (1) e.g. telescope mirror, by ends in diametrically and diagonally zones opposite and near a periphery of the optical surface. A connection between the element and the optical surface has rigid fixations joining two flexible and fixation zones along degrees of freedom. The element is made of material e.g. cesic(RTM: ceramic matrix composite material), glass, ceramic material, metallic material or composite material. The controlling unit has a cell including seven branches alternatively made of aluminum and fiber glass.</p> |
