Q-Motion Miniature Piezo Nanopositioners

(Nanowerk News) Precision positioning systems specialist Physik Instrumente (PI) recently introduced a new series of miniaturized, piezo-driven linear positioners at the 2015 Photonics West conference -- the world’s most important trade show and conference on photonics developments.
PI’s new Q-Motion positioning stages are ultra-compact, only 22mm wide come with travel ranges from ˝” to 1 inch (26mm).

Q-522, Miniature Positioning Stage.
Q-522 Compact Positioners, Economical in Open and Close-Loop
Several options are available for the Q-522 stage series, from economical open-loop designs, to low-cost closed-loop versions and high-end feedback sensors providing 1nm resolution.
Vacuum compatible stages are also offered and a non-magnetic option is in preparation.

Cost-Efficient Inertia Drive System
The drive principle is based on a cost-efficient piezo inertia drive motor (stick-slip). Stages and drive can be customized for larger production quantities.
Self-Clamping at Rest, High Stability
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.
Applications of the Q-Motion Miniature Linear Stages
Precision positioning and alignment of compact opto-mechanical components both in research and OEM instrumentation. Fields of application include photonics, bio-technology, nanotechnology, precision-optics, life-sciences and medical design.
Custom Designs for Industrial Customers
PI has a long history of working with instrumentation manufacturers and can easily modify existing designs or completely customize piezo devices to fit the exact requirements of the application.
