PI Group Launches Economical Sub-Miniature Precision Positioning Stages at 2014 Photonics West

PI (Physik Instrumente) LP just introduced a new generation of economical, miniaturized positioning stages with piezo-inertia motor drives at this year’s SPIE Photonics West conference. Linear and rotation stages are available in open and closed loop designs.

Small, Self-Locking, Low Power, Nanometer Resolution

The new LPS-22 series of economical mini positioning stages are driven by a compact piezo inertia motor. They are offered with travel ranges of ¼ inch, ½ inch and 1 inch. Featuring dimensions as small as 22x22x10mm, the LPS-22 is one of the smallest precision linear stages currently available on the market.
Open-loop and encoder equipped versions are available enabling resolution down to 1 nm. The optimized piezo motor drive allows for push/pull forces to 3N (1/2 pound) and velocity to 10 mm/sec. The new linear stages can be combined to XY units and rotation can be added in form of the new RPS rotation stages. These ultra-low profile rotators available with diameters of 14, 22 and 32 mm and feature a profile height as low as 7mm. No adapter plates are required for mounting.

Applications
Optics alignment & assembly, photonics, microscopy, beam-line instrumentation, medical engineering and bio-technology

Options, Drive Electronics
The stages are available in open-loop versions and with direct encoders for closed-loop operation. Vacuum and non-magnetic designs are also available. Several drive options from OEM driver boards to closed-loop servo controllers with USB interface are offered. Custom designs are also available.
