Very precise fine positioning and control is easily achieved through the combination of a stable closed-loop control system and an associated joystick option. These stages can be motorized with stepper motors and brush-less servo motors with encoders. 

Optional high-resolution, non-contact linear encoder is available. This non-contact encoder offers exceptional repeatability and stability over a range of operating conditions. Both digital and analog output versions are available with resolutions in sub-micron range.
