AUBURN, Mass., Aug. 26, 2016 — Physik Instrumente LP has announced the M-122 low-profile, motorized positioning stage with a footprint of 60 × 86 mm and a travel range of 25 mm. The compact, closed-loop positioning stage can handle payloads to 11 lbs, with velocity to 20 mm/sec. The optical linear encoder provides 100-nm resolution and better linearity and repeatability compared to rotary encoder or stepper motor equipped positioners. Long service life and excellent guiding accuracy with minimal backlash are guaranteed by the preloaded ball-screw drive and precision crossed roller bearings with anticreep cage assist. The device is best suited for research and industrial applications including fiber alignment, metrology, quality assurance testing, photonics packaging, test equipment and micromachining.
