Description

The PSH 40 SG was developed as a fine-steering mirror to withstand challenging environments, such as rocket launch conditions and external shocks. Typical applications include aerospace vehicles, as well as space to ground communication.

Mirror positioning is possible within a tilting range of up to ±18 mrad (open-loop), and ±15 mrad (closed loop).

The tilting system PSH 40 SG can be equipped with an integrated positioning sensor. Positions can be controlled exactly, and a previously established tilt-range can be set. The positioning is highly repeatable with 13 µrad accuracy. Due to the three piezo-stack design, tip-tilt motion is possible in two axes, while the pivot point can be moved to allow for highly adjustable beam guidance.

The system has completed a series of shock, sinusoidal and vibration tests and is ready for use in applications in challenging environmental conditions. The system has a small form factor with a height of only 32 mm and a weight as low a 140 g (depending on housing options).
