High Performance Linear Positioning Stage with Low-Expansion Glass-Scale Encoder and Precision Ball-Screw Drive 

A compact, high performance linear positioning stage featuring smooth travel and high-load capacity has been introduced by Aerotech. The new MPS75SLE stage is designed for production and research applications in optics, surface metrology and general purpose high-precision alignment.

Its precision ground, preloaded ball-screw and linear encoder provide outstanding accuracy, repeatability and a positioning resolution capability to 25 nm. The anti-creep crossed-roller bearings provide exceptionally smooth travel and high-load capacity in a compact package.

The stage has a low thermal expansion (3.3 ppm/˚C) precision glass scale that assures high accuracy and repeatable positioning over long periods of time.

Motor options include a DC servomotor with a high-resolution rotary encoder or a stepper motor. Optional bellows waycovers are available for applications where contamination may occur.

A wide range of adapter brackets supports mounting compatibility across Aerotech’s entire MPS family of stages. This allows users to assemble multi-axis configurations with other linear and rotary stages.

Aerotech is a leading global supplier of positioning and motion control products for industry, government, science and research institutions. Its products provide critical performance for demanding applications requiring high precision, high-throughput motion control solutions.
