One of two Gaia M4 mirrors undergoing inspection at the premises of Advanced Mechanical and Optical Systems (AMOS) in Liege, Belgium, in December 2009.

The 190 × 69 mm mirror was fabricated from sintered silicon carbide (SiC) by Boostec at Bazet near Tarbes, France.

The mirror surface was coated with a layer of silicon carbide using chemical vapour deposition (CVD). The CVD layer of all Gaia mirrors is applied by Schunk Kohlenstofftechnik in Heuchelheim, Germany.
