Original Press Release:
Mini Nanopositioning Stage Based on High Dymamic Voice Coil Motor and Maintenance-free Air Bearing Slide
Cleanroom-compatible, this new high performance noncontact miniature linear slide from PI is suited for applications like wafer inspection, scanning/metrology, fiber alignment, laser micromachining and marking, autofocusing, and genome sequencing.
May 2021, Auburn, MA – PI’s air bearing motion product line is expanding again. The new A-142 high performance compact nano-positioning and linear alignment stage is designed with a voice coil motor and frictionless air bearing slide for highly repeatable motion with outstanding accuracy. This low-profile nanopositioning stage (only 27 mm high (1.1”)) is maintenance free, and due to its non-particle generating drive and guiding principle, cleanroom compatible. It delivers 10mm (0.4”) of hysteresis-free linear travel of its 75x80mm (≈3x3¼”) moving platform while supporting up to 3kg (6.6lbs) loads. The air bearing guide guarantees straightness of 100nm and flatness of 0.5µm. High motion performance is achieved with an integrated voice-coil motor that achieves a max. velocity of 450 mm/s and acceleration of 20m/sec2, a great advantage in dynamic scanning and positioning applications. That’s small and fast! Greater flexibility for alignment and metrology operations in Z is achieved with an optional pneumatic counterbalance to allow vertical mounting without a loss of motor performance. The A-142 can be operated as a standalone nanopositioning device, but for multi-axis motion requirements, combinations and integration into XY and XYZ assemblies are also available.
High accuracy industrial automation processes in fields such as semiconductor test and metrology, genome sequencing, bio-tech, medical engineering, high resolution microscopy, optics and photonics manufacturing.
