Nanopositioning stages with piezo motors and voice coil motors for precision positioning & scanning are fundamental tools for all fields of high resolution microscopy. The rapid response and sub-atomic resolution allow scientists to create higher-quality images faster.
PI provides a large variety of long-travel stages, voice-coil and piezo-based fast objective lens positioners (Z-Focus motors), fast Z-Scanners (slide-scanners, well-plate scanners, sample scanners) for deconvolution / 3-D imaging (Z-stack acquisition) and fast focusing applications.
PInano® series XY and XYZ piezo stages are known for their very high performance and low cost.
PI's piezo-actuated stages typically achieve 10 times higher speed & precision than classical motorized drives. Controllers come with a USB, RS-232 and TCP/IP digital interface as well as high-bandwidth analog interface, for extremely fast response and compatibility with all major image acquisition packages.

Motorized microscope stages with ultrasonic motor drives are self-locking and provide better long-term stability than conventional lead-screw-driven stages (drift caused by viscous flow in the lubricants). They are also significantly more compact and elegant due to the lack of screws and bulky motors.
PI also offers high-stability preloaded manual stages. Both versions are compatible with the fast piezo nanopositioning stages.

PInano® low-profile piezo microscope stages are available in Z, XY and XYZ Versions. They are optimized for very fast step and settle and easy integration into high resolution microscope applications. They feature a very low profile of 0.8" (20 mm), a large aperture for slide holders, and travel ranges of up to 200 µm with sub-nanometer closed-loop resolution – ideal for leading-edge microscopy and imaging applications.
Why Choose PInano® Microscope Stages?
PInano® Z-stages can provide advantages over objective scanners, when multiple objectives are to be used on a turret. The slide-mount at the bottom enables full rotation of the turret.
PInano® XY and XYZ stages are also available. They are designed to provide high performance at minimum cost. Standard versions are equipped with high-performance piezoresistive sensors. If the best possible stability and linearity is required, capacitive-metrology equipped versions are recommended.

PI offers a large variety of standard and custom Objective NanoFocusing Stages.
Why Choose PI PIFOC High Resolution Microscope Ojbective NanoFocusing Scanners?
Objective NanoFocusing Scanners provide advantages over sample scanners when speed is an issue or when the specimen needs to be absolutely stationary. The compact design of the objective scanner allows for a stiffer design and faster response. In addition, fast motion over long travel ranges is possible without side affects, because significantly less mass has to be moved than with a complete sample positioning stage.
Longer Travel: New Objective Z-Focusing Scanners for Autofocus, Surface Metrology and Pathology
The latest PIFOC fast piezo focus motors provide 800µm travel and were redesigned for higher stiffness, faster settling and higher performance.
For even longer travel up to 7mm (7,000µm), a novel Voice-Coil-Motor for Autofocus - vertical linear slide scanner with magnetic counter balance is also available.
