High Stability Optical Benches for Darwin<br />

The functionality and the performance of future science interferometric missions like DARWIN are based on the availability of<br />

ultra-high stability optical benches capable of maintaining dimensional stability of picometers over periods of hours without<br />

active control. This activity aims to assess the optical system technologies and materials suitable for achieving these stability<br />

and design, develop and test a representative scaled optical bench under cryogenic conditions demonstrating picometer<br />

stability over periods of up to 3 hours.<br />
