Miniature gear-drive rotary stages

Clear apertures of 20 or 30 mm allow the stages to be used effectively where through-holes are required. These applications include articulation of beam polarizing lenses, through-holes for cabling or air lines, or vision/camera/inspection.

Designed for 360-degree measurement, alignment and inspection in optics, photonics and lasers, the stages incorporate a precision worm-gear drive mechanism and bearing components. They are available with DC servo or stepper motors. Accuracy is up to 80 arc seconds, resolution is 1 arc second, repeatability is 6 arc seconds, and maximum speed is 180 degrees per second. Top load capacity is 12 kg.

Both stages are available with optional vacuum preparation to 10^-6 torr including a vacuum-rated motor/feedback connector. An optional breadboard mounting plate provides direct mounting to both English and metric optical tables and a Lens Mount Option (LMO) permits easy mounting of standard lenses over the stage aperture

The rotary stages can be easily mounted together in numerous combinations with linear, goniometer and vertical-lift units in Aerotech’s MPS (Miniature Position Stage) family.
