LISA Pathfinder, the technology demonstration mission for the space borne gravitational wave detector LISA, will carry two free floating test masses whose position and attitude will be measured by an interferometric readout. The interferometer consists of about 20 elements assembled on one optical bench. Each of these elements will have alignment precisions in the order of 10 µm and 50 µrad. These alignment tolerances influence the measurement precision, cause cross coupling of the heterodyne interferometer signals and contribute to the static test mass attitude in flight. We will present results from various alignment investigations for LISA Pathfinder and experimental results.
