Piezo tip-tilt mirror positioners   

nPoint Piezo Tip-Tilt Stages   

For applications requiring accurate beam steering or high-speed deflection, a mirror mounted atop a piezo tip-tilt stage is ideal.

The nPoint range of RXY nanopositioning piezo stages are optimised for use with up to 3" optics, and designed for open-loop and closed-loop applications.

nPoint's nanopositioning systems utilise unique designs to ensure high resonant frequencies with minimal orthogonality and cross-talk errors. Their tip-tilt specific 402 series DSP controllers enable superb motion linearity and positioning accuracy, easy optimisation of the piezo system's response time, and flexibility in programming for the user's application.
