Abstract Beam steering is a critical issue in optical space applications. The technical requirements with respect to the angular and translational beam alignment and the optical path length are at the limits of current mounting and optical component fabrication technology. Furthermore, stability is of paramount importance, since long and short term fluctuations in temperature as well as shocks and vibrations during space missions can dramatically affect the performance of the optical components and of the whole system. This work focuses on experimentally demonstrating novel techniques, using passive optical components, which allow precise beam-steering on an optical breadboard. The passive optical components are inserted to the system to compensate for inaccuracies during manufacturing stages of the components. Therefore, the manufactured components do not need to be flawless so the manufacturing tolerances are relaxed thus reducing the required technologies. Moreover, these techniques are less sensitive to misalignments and lead to reduced precision requirements by the optical components. Lastly, the stability of these techniques is also tested on prototype optical breadboards.
