This animated sequence depicts a three-dimensional view of the telescope elements and focal plane of Gaia's payload module, with the light path for one field of view highlighted. The two large primary mirrors each measure 1.45m × 0.5m and rest on top of the optical bench. The mirrors and structural support are all made out of ultra-stable silicon-carbide material.
