Manual Rotation Stage, Steel, 46 mm Diameter, 4° Fine Travel, M4 and M6

Precision Steel Rotation Stages, UTR Series

The M-UTR46 Precision Rotation Stage is ideal for ±2° fine-tuning angular orientation of any component after rotating it to an approximate angle. Ball bearings are preloaded in precision-ground, tool steel races for a smooth, accurate trajectory with minimum eccentricity. Disengaging the side-mounted clutch knob permits continuous 360° free rotation. Once the approximate angular orientation is obtained, a zero-backlash manual drive provides a fine adjustment of 4°. Scale markings and a vernier on the side of the rotation stage measure angular position with 30 arc min resolution.

Components may be mounted to the top of the 46 mm diameter rotation stage via M4 and M6 tapped holes. Please refer to the Related Products for possible options.

360° Coarse Rotation - 4° Fine Rotation

Disengaging the side-mounted clutch knob permits continuous 360° free rotation. Once the approximate angular orientation is obtained, a zero-backlash manual drive provides a fine adjustment of 4°, which can be locked down by the lock knob opposing the fine adjustment knob once the final alignment is achieved. Scale markings and a vernier on the side of the rotation stage measure angular position with 1 arc min resolution. Sensitivities range from 2 to 6 arc second depending on the model.

Table Mounting

UTR Series stages can be table mounted using the optional PBN Series Base Plate. Stages mount with the included BR Series Mounting Bridles, through the stage collar near the base. Shown in the photo is a UTR80S mounted to a M-PBN8 base plate. Alternative solution for table mounting is to use Mounting Bridle when the base plate cannot be used.

Vertical Orientation Post Mounting

Although they are most commonly mounted horizontally, (M-)UTR80S low profile rotation stages can be post mounted in a vertical orientation using the M4 threaded hole located on the side of the stage. Shown in the photo is a UTR80S mounted to 1 in. optical pedestal.
