ADS designed for INAF the 13 m vertical optical bench for the calibration of the adaptive secondary units located inside Arcetri observatory solar tower telescope.
This facility is actually a 5 ton 1 m diameter tube, which is suspended inside the structure of the old solar tower by pneumatic isolators: at its top end is placed the deformable mirror to be tested, while on the bottom there is the AO bench and the optical isntrumentation. The 13 m optical path runs inside the tube, which is vacuum proof and thermally controlled.
