The PSM Piezo Steering Mirror Mount provides high-speed, sub-microradian resolution, tip, tilt, and Z motion for mirrors, gratings and other optics. Equipped with a direct piezo actuation system without lever arm transmission, the PSM2 is ideally suited for high bandwidth laser beam steering, switching and stabilization, beam scanning, image stabilization, and laser cavity tuning.

Fast and reliable motion is supplied by three multi-layer, low-voltage piezo stacks in a right triangle configuration. The length of each piezo stack can be controlled individually. Applying a voltage to one stack, results in a tip or tilt. Changing the length of all three stacks simultaneously, results in a linear Z-displacement. The PSM features a high unloaded resonant frequency of 5400 Hz.
The parallel motion design of the PSM is fully temperature compensated. Changes in the environmental temperature do not affect the tilting angle. They are also maintenance-free and are not subject to wear. The PSM models are internally preloaded, can be mounted in any orientation, and support mirrors up to 50 mm diameter that can be glued directly to the top plate.
The closed-loop versions feature high resolution strain-gauge position sensors for highly accurate and repeatable motion which also compensates for actuator creep. The assembly is done as a full Wheatstone bridge and is temperature insensitive. The closed-loop devices can be used in either open or closed-loop control.
With positioning resolution as low as 0.004 µrad, the PSM Piezo Stack Steering Mirror is capable of ultra-fine adjustments with resolution only limited by the noise of the control electronics.
The PSM is also available as an open-loop (no position feedback) device. This is ideal for applications where the position is controlled by an external sensor such as a lateral effect diode, quad cell, photodiode, CCD camera, etc.
