Two mirrors are used on FIP beamline for vertical focussing. They also allow to reject high order harmonics found in the white beam. Typical calculated reflectivity curves are given:

 These mirrors, and the benders, are manufactures by the SESO Cnie (France). A photograph of the bender and a zoom on the actuators is available.

The vessels of both mirrors (the first and the second one) have been manufactured by IRELEC (France). The first vessel is in ultra-high vacuum, the second one in high vacuum.

Some other geometrical informations are available:
