PR50PP 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 PR50PP stage is a cost-efficient alternative to the SR50 for applications that do not require the high-resolution and precision of the SR50, or for applications that could benefit from higher speeds up to 20°/s. The PR50PP stages feature angular resolution of 0.02° with an open-loop stepper motor in half-step mode. The stage is equipped with a hardware origin and allow for continuous rotation of 360°. The central aperture is threaded 1.063-20 in. and PR50 stages are shipped with two, same diameter retaining rings to allow mounting of any ø,25.4 mm diameter optics within the aperture. Four M3 holes allow for attachment of custom top plates. Due to its very low profile, the PR50 stages contain pressure sensitive components. For use at a pressure level below 0.25 bar, please contact our sales department.The EQ45 bracket can be used for vertical mounting of a PR50 stage.
