Manual Rotation Stage, Steel, 1.81 in. Diameter, 0.91 in. Height, 4° Fine, 8-32, 1/4-20
Model: UTR46S
Product Series Overview
Precision Steel Rotation Stages, UTR SeriesThe UTR46S Precision Low-Profile 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 1.81 in. diameter rotation stage via 8-32 and 1/4-20 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
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.
