Description

Details

SURES hexapod is particularly adapted to the fields of space, astronomy and telescopes. For example it can align M2 and M3 mirrors on ground-based telescopes to realign them correctly to compensate the deformation of the structure due to gravity changes and temperature variations during the night.

The mechanics and electronic components of SURES hexapod are designed to work in cold environment as most of ground-based telescopes are installed on top of mountains in high altitude.

Applications

► Positioning of M2 or M3 mirror on optical telescope

► Positioning of subreflector on radio telescope

► Optical adjustment
