'Dithering stages' nano-position very
precisely
'Dithering stages' provide sub-nanometer resolution, millisecond responsiveness and low cost for nano-positioning, resolution enhancement and scanning applications.
PI, a leading manufacturer of nanopositioning and piezo-based precision motion-control equipment for lifescience, photonics and semiconductor applications, offers the high-speed, low-cost P-713/P-714, XY-dithering stages for resolution enhancement and scanning applications Fast dithering between pixels increases resolution - these low-cost, piezo-driven stages feature a very high resonant frequency of 2.2kHz for millisecond responsiveness

Precision linear stages are at affordable price
For precision automation uses, a motorized family of high-precision linear stages are combined with low-cost servo motor controller to form very affordable motion control systems.
Closed-loop scanning stages are flexure-guided
Closed-loop flexure-guided piezoelectric scanning stages provide a record travel range of 1000 microns and allow nanotechnology/precision microscopy probing of larger areas than before.
Integrated ultra-long life piezoelectric drives provide sub-nanometer position resolution, important for high-resolution interlacing applications where the optical resolution of a CCD or CMOS sensor is increased by shifting it at high frequency between pixel positions.
* Flexibility - open loop and closed loop models - open loop (P-713) and closed loop (P-714) models are available.
Both versions were specifically designed for highly dynamic scanning and tracking tasks.
The closed-loop version provides higher linearity, the open loop version costs less.
The stages feature a very low profile of only 6 mm for easy integration in various other applications such as scanning microscopy or in static nanopositioning tasks.
Application examples include resolution enhancement in imaging sensors; scanning microscopy and nanopositioning.
Features and Advantages are as follows.
* Award-winning ceramic-encapsulated piezoelectric actuators for longer lifetime.
* Easy integration, only 45x45x6mm.
* Ideal for OEMs, Lower Cost than Conventional XY Piezoelectric Scanners.
* Parallel-kinematics direct drive with 2.2kHz resonant frequency for faster settling and higher scanning rates.
Control Electronics - a variety of standard and low-cost OEM controllers in analog and digital design is available to drive these stages.
* About PI - PI, a global, ISO 9001 certified market leader in the field of nanopositioning technology, has been developing and manufacturing standard, custom and OEM products with piezo and motor drives for 35+ years.
