Application of polarising optics in space interferometry — •Marina Dehne, Benjamin Sheard, Gerhard Heinzel, Michael Tröbs, and Karsten Danzmann — Albert- Einstein-Institut Hannover, Max-Planck-Institut für Gravitationsphysik und Universität Hannover, Callinstr. 38, D-30167 Hannover

Polarising optics will play a key role in future satellite projects like the LISA mission or a GRACE follow-on mission. In these missions it is foreseen to use polarising components in the laser interferometer for beam steering. It is therefore important to investigate the influence of these components on the interferometer sensitivity and to validate the length stability. The talk will describe the design and construction of a quasi-monolithic interferometer for comparing the interferometric performance of non-polarising and polarising optics. Preliminary results will be presented.
