Fast Steering Mirrors, or FSMs, from piezosystem jena play critical roles in modern optical inter-satellite communication terminals.

As the workhorse of these terminals, an FSM allows for the stabilization and precise pointing of laser links between satellites. This is vital as a stable and secure connection is absolutely necessary for the efficient and consistent transfer of data. Especially in low earth orbit, atmospheric turbulence along with onboard vibrations can cause misalignment and link breakage. FSMs provide a solution by countering these vibrations through extremely fast and precise motion.

Our FSMs:

• Displacements up to ±20 mrad.

• Sub-microradian resolutions.

• Closed-loop strain gauge feedback for elimination of hysteresis and drift.

• Bandwidths up to 6500 Hz.
