The SR50PP Compact Rotation stage is designed to rotate optical components up to 1 inch diameter, such as polarizers, wave plates, or wedges. The small size allows use in confined spaces, such as laser cavities, disk texturing machines, or manufacturing areas for fiber optical components. The lightweight, low profile design incorporates an aluminum body with pre-loaded ball bearings. This proprietary ball bearing design provides smooth rotation with minimal wobble. A precision ground worm gear produces consistent driving torque to the rotating carriage and eliminates variations in motor current. The motor is folded inside the stage body to give an extremely small footprint for a stage at this level of precision. The SR50PP stage features an angular resolution of 0.001° achieved with a open loop stepper motor. The stages are equipped with a hardware origin allowing the stage to return to a reference home position to within 0.01°. SR50 stages can run in continuous rotation mode.
