PI (Physik Instrumente) recently added a new piezo inertia drive rotary stage to its existing Q-Motion product line of compact linear and rotary systems – the Q-632. This compact micropositioning drive is only 32 mm wide, 7 mm high, and has a 30 mm turntable diameter with 360° rotation range.
The Q-632 delivers precision rotation with minimal incremental motion of 3 µrad in closed-loop operation and velocity of 45°/sec. The self-clamping motor design provides long-term power-off position-hold capabilities without the need for a brake — another space and energy saving advantage of the Q-Motion positioner series. All Q-Motion rotation stages are suitable for a vacuum to 10-6 hPa; ultrahigh vacuum-compatible versions are also available on request.
The Q-600 series of miniature rotary stages include the smallest motorized stage that fits on a finger-tip – the Q-614, with a 14 mm diameter turntable and velocity 70°/sec.
The Q-632 offers variety with open and closed loop versions. The closed-loop version is equipped with a direct measuring sensor providing 0.75 µrad resolution.
The stages provide precision positioning and alignment of compact opto-mechanical components in research and OEM applications. Ideal applications include automation, photonics, bio-nano-technology, metrology, microscopy, life sciences, micro-manipulation, and cleanroom applications. Vacuum and non-magnetic options are also available.
