Motorized Stage Specification Comparator

Selecting a motorized translation stage requires matching drive technology and bearing type to application constraints simultaneously. A stepper-driven lead-screw stage offers self-locking and low cost but minimum incremental motion (MIM) in the hundreds of nanometers range; a linear-motor air-bearing stage achieves sub-nanometer MIM and velocities above 1 m/s but cannot be used in vacuum. Enter required travel range, MIM, maximum velocity, load capacity, accuracy, operating environment (standard, high-vacuum, or UHV), and whether the stage must hold position unpowered. The tool scores nine common drive-and-bearing configurations against each specification, ranks them, and highlights the best match — including vacuum-rated options for optical systems inside a chamber.
