The AG-LS25 is a high precision miniature linear stage featuring Newport’s new, Agilis™ piezo step direct motor. The AG-LS25 provides the benefits of a motorized component, ultra-high adjustment sensitivity and convenient remote operation, at a price and size comparable to that of a high quality manual stage.
The AG-LS25 features 12 mm travel in an ultra-compact and light weight package compatible with our SDS25 and DS25 manual linear stages. Precision motion is achieved by calibrated, pre-stressed linear ball bearings. The thermally matched stainless steel design and precision manufactured bearing surfaces provide ripple-free, low friction linear travel and angular deviations better than 100 mrad in any axis.
The Agilis piezo motor is directly coupled to the moving carriage with no intermediate screw or gear. When idle, the holding force of the motor locks the position for true set and forget long term stability. Compared with alternative screw driven designs, the AG-LS25 compromises neither adjustment speed nor life time, and has no backlash. In contrast to ultrasonic motors, the Agilis non-resonant motor makes small incremental adjustments more predictable with 50 nm incremental motion capability, ideal for ultra-sensitive alignments. For absolute positioning, for instance returning to a set position, the ...

In contrast to ultrasonic motors, the Agilis non-resonant motor makes small incremental adjustments more predictable with 50 nm incremental motion capability, ideal for ultra-sensitive alignments. For absolute positioning, for instance returning to a set position, the AG-LS25 features a precision electrical limit switch. This switch acts not only as a safety device, it also allows measuring the average step size by counting the number of steps from the left travel limit to the right travel limit and vice versa. As the average step size of the AG-LS25 under the same conditions is repeatable, it is possible to move to an absolute position without the need for expensive encoder feedback. High level commands to determine the current position and to move to an absolute position (x% of travel) are integrated in the AG-UC2 electronics.
