Abstract
To increase the collecting power and to improve the angular imaging resolution, space telescopes are evolving towards larger primary mirrors. The aerial density of the telescope mirrors needs to be kept low, however, to be compatible with the launch requirements. A light-weight (primary) mirror will introduce additional optical aberrations to the system. These may be caused by for instance manufacturing errors, gravity release and thermo-elastic effects. Active Optics (AO) is a key candidate technology to correct for the resultant wave front aberrations. One important element in the adaptive optics correction chain is the deformable mirror, which corrects for the aberrations by manipulating the wave front. While deformable mirror technology for ground based applications is already widely available and reasonably mature, for space applications several development steps need to be made to comply with the different set of requirements. This is mostly due to the challenging environment, high reliability requirements, and the specific nature of the adaptive optics correction loop.
