The PSH 20/2 and PSH 35/2 are part of a new series of tip-tilt systems designed to deliver high dynamics with resonant frequencies of up to 2 kHz and a wide tilt range of up to 44 mrad in open-loop. The same housing allows customers to choose between the PSH 20/2 (optimized for rapid tilt applications with lower capacitance and reduced energy consumption), and the PSH 35/2 (which offers a longer stroke and a broader temperature range) – ideal for achieving the highest precision in challenging environments.
These actuators provide tilt to the top plate on 2 rectangular axes. The construction is temperature compensated so that changes of the surrounding temperature do not affect the tilting angle. These tilting positioning stages are designed for plus/minus tilting. The mirror mounts are preloaded, thus they are well suited for dynamic applications. Strain gauge (SG) variants are optional and provide a precision feedback measurement system. The PSH 20/2 and PSH 35/2 are designed for mirrors with a maximum diameter of 32 mm.
Developed in collaboration with the European Space Agency (ESA) for the SQATTS (Space Qualified Tilting Systems) project, the PSH 20/2 and PSH 35/2 systems have successfully met the rigorous standards for space qualification.
