The bending actuators are designed for easy adaptation for different mirror widths and thicknesses, and are very compact in the direction of the X-ray beam, so that the whole device is only 20 mm longer than the mirror substrate. The ALBA adaptive optics device The active optics system developed by ALBA (Figure 5) is essentially a mechanical mirror bender with point force actuators along the mirror length. The development of X-ray photon science has been characterized in the last few years by the development of free electron lasers and the so-called diffraction limited storage rings. The use of helicoidal springs enables the bender for an excellent dynamic range, and it is capable of applying forces up to 1 kN, with a below 1 mN, sufficient to ensure that the bender actuators can apply is 1,000 , enough to bend a flat mirror to curvatures below 100 m, with steps corresponding to a change of height below one nanometer.
