The mirror tilting systems (PSH series) consist of a variety of elements for high speed scanning and mirror shifting. The fast movement of mirror and other optical components, in particular, make the PSH series well suited for many applications such as high speed scanning, eye tracking, laser beam steering, etc.

The key features of the mirror tilting systems include a high resonant frequency in the kHz range and nearly unlimited resolution in the sub-nm range.

The principle of preloaded direct driven actuators allows the systems of the PSH series to be used for the precise positioning of heavy components as well. Long term stability without drift and hysteresis are guaranteed by the use of the optional integrated position feedback sensors.
