Microscope Stages
Jun 2011
PI (Physik Instrumente) L.P., Air Bearings and Piezo Precision MotionRequest Info
AUBURN, Mass., June 24, 2011 — PI (Physik Instrumente) LP has added two models to its PInano superresolution microscope stage series.

The new models have direct-measuring capacitive sensors that provide higher linearity and long-term stability than do piezoresistive sensor-equipped stages, and they are less sensitive to noise, according to the company, because of a high-frequency measurement principle, as opposed to the DC-based sensing technique used in piezoresistive sensors.

The large aperture accommodates microscopy accessories such as slide holders and petri dish holders. The recessed bottom slide mount allows full rotation of the turret without in-and-out Z-motion, protecting objectives from crashing into the stage on turret rotation.

Both X-Y and X-Y-Z stages are available. The low-profile design of 20 mm facilitates integration into inverted microscopes from Leica, Nikon, Olympus and Zeiss.

An optional 25 × 25-mm positioning stage with self-clamping ultrasonic ceramic motors provides a stable basis for the piezo scanning stage and enables imaging of large samples.

The stages are compatible with all major image acquisition software packages, such as Micromanager and Metamorph.

Features include a 24-bit controller with USB, Ethernet and RS-232 interfaces and analog control, 200-μm travel and closed-loop control for subnanometer precision.
