A large number of optical systems used in space applications, require stable optical benches that are extremely robust, reliable and efficient. A major challenge in these applications is coupling light into single mode optical fibers after having traversed a number of active and passive optical elements. This leads to high level of complexity for the benches and for the subcomponents used. As a consequence of trade-offs between robustness, complexity, reliability and constrains in manufacturing, coupling efficiencies lie typically from 50% to 80% at the cost of an increased complexity of their sub-components and procedures. Here we report a novel scheme, which allows precise beam-steering for fiber-free space-fiber systems on a Zerodur breadboard using optical wedges and flats. Our approach greatly reduces the precision required for the sub-components as well as the complexity of the fiber couplers used. We present an in-depth theoretical treatment of the optical scheme, using both analytical and numerical simulations. We corroborate the results of the simulations with preliminary tests performed.
