Abstract

The assembly and integration of the breadboard cryogenic optical delay line has been completed. The measured optical path difference stability is 1.3 nm rms on a test bench with 23 μm rms vibration level (the test bench has a much higher disturbance spectrum than the DARWIN spacecraft). A full verification test program is currently being carried out by Alcatel Space and SAGEIS-CSO, including thermal vacuum testing at 40 K.
