The NASA-DLR collaboration BECCAL will be a multi-user-multi-purpose facility for the study of Bose Einstein Condensates in the microgravity environment of the International Space station. Its laser system provides light distribution and frequency stabilization and must be robust and compact to withstand the rocket launch and temperature fluctuations during the runtime on the ISS. To this end a toolkit based on the glass ceramic Zerodur is developed, that has already successfully been used on numerous space missions like FOKUS, KALEXUS or MAIUS. This poster discusses the optical modules developed and tested for BECCAL. Our work is supported by the German Space Agency DLR with funds provided by the Federal Ministry for Economic Affairs and Energy (BMWK) under grant number 50 WP1433, 50 WP 1703 and 50 WP 2103.
