A precision linear stage is a positioning device providing linear motion with high accuracy and minimized runout errors. Motorized linear stages with high resolution and motion fidelity are critical to the success of industrial and scientific applications from beamline systems to semiconductor manufacturing and photonics instrumentation.
From Cost-Effective to Ultra High-Performance Linear Stages
Linear stage designs vary from low cost, stepper-motor-driven positioning and indexing tables, to closed-loop motorized stages with linear encoders for direct position feedback and the highest positioning accuracy. Modern linear encoders achieve nanometer resolution and better. When the highest performance, speed and the best velocity control are required, electromagnetic, direct drive linear motors are recommended. The direct-drive principle increases overall performance and eliminates friction, wear and losses that occur when rotation is converted to linear motion.
For the highest geometric and positioning performance over longer travel ranges, direct drive linear stages with air bearings are available.
