PSM2

Article: 00090341

Rotary stage / piezoelectric / motorized / Z-axis

Ultra-fast, two-axis rotation and linear z-motion for up to 50 mm diameter optics
Piezoelectric travel range of 2 mrad or16 µm
Direct piezo design provide high-bandwidth control
Ultra-compact

The PSM2 is a high-speed, tip, tilt, and z motion piezoelectric stage for mirrors, gratings and other optics with sub-microradian resolution. Equipped with a direct piezoelectirc actuation system, minus the 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 (PZT) in a 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.
For simple operation, the three piezo stacks of the PSM2 are arranged in a right triangle configuration. This results in orthogonal rotation without the need for coordinate transformations that is required in designs where the piezo stacks are placed at 120° intervals.
