Static & Dynamic

Instruments for use in ground-based observatories are often mounted on the back of the telescope and so swing through the sky as the telescope tracks the stars during a night of observing. The ultra-precise alignment of the optics must be preserved during this motion so the instruments, which sometimes weigh several tonnes, are designed and tested to withstand the flexure encountered.

Most instruments have moving parts within them, either for the operation of shutters and filter wheels or robotic arms to position optical components. We have extensive experience of designing suitable mechanisms which - as well as offering extreme precision - can also operate at very low (cryogenic) temperatures and may even have to withstand the forces and vibrations involved in the launch of the space craft carrying them.
