Stepping drives offer compact solution
The Nexact OEM stepping drives offer virtually unlimited travel range, very high positioning resolution in the sub-nanometer range and a highly compact design.
PI's third line of piezo linear motor drives combines unlimited travel range, sub-nanometer resolution and high dynamics in a very compact package Precision motion over several millimetres with high-position-resolution places great demands on drive hardware

Infrared Imaging : The best gets better
Viewing infrared wavelengths between 0.4-1.5microns, the converted image produced by the new 7215 is now brighter and offers edge to edge sharpness.
Infrared Imaging at Telecomms Wavelengths
The widely used Electrophysics 7290A Micronviewer Infrared camera has now been enhanced with increased sensitivity at both 1310nm and 1550nm.
Not only do dynamic performance and generated force requirements have to be considered for each application, but also the available space.
The Nexact piezo linear drives now fill the niche between the fast, flat PILine drives (50nm resolution, up to 800mm/s) and the heavy-duty, ultra-precise Nexline drives (up to 600 N, sub-nanometer resolution).
The Nexact OEM stepping drives offer virtually unlimited travel range, very high positioning resolution in the sub-nanometer range and a highly compact design.
The N-310 measures 25 x 25 x 8mm and is vacuum-compatible and nonmagnetic.
Nexact technology uses the PiezoWalk drive principle that combines two operating modes: step motion for unlimited travel range and a highly-dynamic linear (analogue) mode for sub-nanometer resolution within a step.
The runner of the linear drive is moved forward or backward by piezoelectric actuators, which alternately clamp and drive it.
In the linear mode, all the piezo actuators clamp and drive the runner together without stepping.
Nexact differs from Nexline in its smaller size, lower force generation and lower operating voltage of less than 40V.
For ultra-precision nanopositioning applications, the E-860-series Nexact driver/controller series supports both stepping and linear modes in open and closed-loop operation. Request a free brochure from Lambda Photometrics ...
