Schematic view of the optical layout of the LOREA beamline.

The first optical element inside the optical hutch is a flat mirror (M1). It is internally cooled with water to reduce the surface deformation due to the heating. The following element is in the experimental hall and it is the monochromator (green square), which includes three switchable spherical mirrors (SM), and four varied-line-spacing (VLS) plane. Downstream the monochromator there is a plano-elliptic mirror (M3), which focuses the source horizontally at a plane placed 0.5 m upstream of the exit slit. The beam is vertically focused by the monochromator mirrors at the exit slit plane. Finally, a Kirkpatrick-Baez (KB) mirrors pair (blue square, with one vertically deflecting mirror, VFM, and one horizontally deflecting mirror, HFM, both with a plano-elliptic figure) refocuses the beam on the sample.
