Economical sub-miniature precision positioning stages

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 22×22×10mm, 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 1nm. The optimized piezo motor drive allows for push/pull forces to 3N (1/2 pound) and velocity to 10mm/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 32mm and feature a profile height as low as 7mm. No adapter plates are required for mounting.

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

Integrated PIShift type piezo ceramic inertia motors provide several advantages over classical motor drives: smaller, lower energy consumption, nanometer resolution and self-locking, i.e. at the end of each move, the stage locks its platform into place with no drift and no current draw. This provides better stability and removes the need for a motor brake.

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.
