Nanopositioning stage

The SCR100 ultrahigh precision, single-axis stage integrates a slide guide, encoder, and linear shaft motor.

Features & benefits

• Moving-magnet design; cables and connectors located in stationary base; absence of moving cable eliminates motion errors due to cable forces

• Precision-ground cross-roller way provides high stiffness, smooth motion; higher torque levels due to offset loads with travels from 50 to 300 mm

• Noncontact linear shaft motor and optical linear encoders are self-contained; built-in noncontact optical linear encoder comes with resolutions from 1 micron to 10 nm with digital output
