Multi-axis Positioning Systems make use of linear, rotary and goniometric stages, slides and drives in various combinations to create standard and custom positioning systems.
Rotary positioning stages are devices with tables or shafts that may be rotated to any angular position. They may be driven or simple slides.
Microscope stages are platforms where specimens are placed for observation with a microscope. They are often equipped with a mechanical device which holds the specimen slide in place, but allows the back-and-forth and side-to-side movement of the slide.
Linear slides are simple linear motion devices composed of a stationary base and a moving carriage. Linear stages are slides with a drive mechanism that provide controlled, precise positioning along a linear axis.
Piezoelectric motors use a piezoelectric ceramic element to produce ultrasonic vibrations of an appropriate type in a stator structure. The consequent movement can either be rotational or linear depending on the design of the structure.
