The light beams from a collimator array are each aimed at a optical switch array in a converging manner such that the point of convergence of the reflected light beams is at or near the center of a target (e.g., another optical switch array, receiver array, or any other space in which light beams are to be directed). The light beams converge at an imaginary common point behind the plane of the mirrors, at a distance along an optical axis from the mirrors, which is substantially equal to the distance along an optical axis between mirror arrays.
