2016 Neuroscience Conference Debuts PI's Ultra-Stable Microscope XY Stage Packages

High-end system provides 10nm resolution, auto-locking with no drift, for extremely stable images.

San Diego, CA – Physik Instrumente will introduce two new compact XY microscope stages based on ultrasonic piezo direct-drive motors. Model U-761 provides 25x25mm travel and is equipped with 10nm resolution linear encoders, model U-780 provides 135x85mm. 

Ultra-Stable - Ideal for Imaging

PI's patented ultrasonic direct-drive motors feature millisecond responsiveness and provide a wide dynamic range with jerk-free, smooth motion, with velocities from <1 micron/second to 120mm/second. A great advantage over other drive systems is the drift-free self-locking design that clamps the stage down once a target position has been reached. The stiff direct drive avoids servo jitter, which can occur with electromagnetic linear direct drive motors due to insufficient damping.

Accessories

A large aperture and many adapter plates allow for the use of microscope slides, well plates and petri dishes.  An optional PInano Z stage or XYZ piezo flexure stage can be added for applications such as fast focus, single molecule tracking or optical trapping. 

Controller, Software, and Joystick

A controller with extensive software support and a joystick are included in the package.  Joystick mode and computer controlled mode can be switched with one button. The advanced digital servo controller (automatic switchover between static and dynamic PID parameters) is optimized for ultrasonic motors to achieve maximum dynamic performance with settling times as low as a few 10 milliseconds without sacrificing resolution and smooth operation. A comprehensive software package is included: drivers for LabVIEW, dynamic libraries for Windows and Linux, MATLAB, MetaMorph, µManager, Andor iQ. Interfaces include USB, SPI, RS-232 and analog.

Applications of the U-761 and U-780 Microscopy System

Fields of applications include super resolution microscopy, confocal microscopy, tiling, and automated scanning microscopy.

Standard and Custom

In addition to a large variety of standard piezo mechanic stages, PI can quickly modify existing product designs or provide a fully customized OEM part to fit the exact requirements of the application.
