Mirrors in gravitational-wave detectors must be isolated from ground motion. The constant microseism would make it impossible to measure gravitational waves. To achieve the isolation, the mirrors are suspended from multiple cascaded pendulums. These suspensions add random motion of the mirrors on their own. It results from thermal motion of molecules in the suspensions and their resulting internal vibrations.

Using glass (fused silica) suspensions – the same material the mirrors are made from – reduces the disturbing influence of thermal noise. This approach, called monolithic suspensions, was adopted at an early stage (circa 1996) in the baseline design of the GEO600 detector. GEO600 therefore became a testing ground for a technology now used by all gravitational-wave detectors.
