BECCAL is a NASA-DLR collaboration, which will be a facility for the study of Bose Einstein Condensates consisting of potassium and rubidium atoms in the microgravity environment of the International Space Station (ISS). An essential component of the apparatus is the optical system, which takes over laser light distribution and frequency stabilization for several light fields. To ensure this, all system components must for instance be able to cope with vibrations during rocket launch and temperature fluctuations during the campaign. To this end, we are using and extending a toolkit based on the glass-ceramic Zerodur, that has already successfully been used on numerous space missions, like FOKUS, KALEXUS or MAIUS. This poster discusses the optical modules developed for BECCAL. Our work is supported by the German Space Agency DLR with funds provided by the Federal Ministry for Economic Affairs and Energy (BMWi) under grant number 50 WP 1433, 50 WP 1703 and 50 WP 2103.
