Thales Alenia Space wants to make an interferometer measurement on a telescope and thus has to precisely align a big flat miror according to six degrees of freedom: Tx, Ty, Tz, Rx, Ry, Rz.
This autocollimator miror has to be positioned at the telescope’s optical axis height.
SYMETRIE provides an hexapode combining high payload capacity with high precision to align the miror in the six degrees of freedom, as well as its support equipped with an additional vertical translation table (Tz) in order to initially align the miror at the telescope’s optical axis height.
The hexapod works in horizontal orientation, which is the most demanding one with respect to the efforts in the actuators.
The system is fully controled by SYMETRIE-made electronic and ergonomic software.
