Manual Rotation Stage, Steel, 3.54 in. Aperture, 6.26 in. Diameter, 4° Fine, 1/4-20

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.

Each UTR-A manual rotation stage has a center aperture for optical access through the rotation axis or mounting optical components, providing easy integration to systems involving, for example, laser imaging or microscopes. UTR46A and UTR80A stages are all available in a low-profile version UTR46SA and UTR80SA for fitting into more restricted spaces.

UTR Series Stages offer multiple configurations for mounting to tables and other components. These stages can be table mounted using the optional PBN Series Base Plate, with the included BR Series Mounting Bridles through the stage collar near the base. UTR80SA stage features an M4 threaded hole located on the side for post mounting in a vertical orientation. UTR rotation stages can also integrate with UMR Series Linear Stages and TGN Series Tilt Stages to build a multi-axis positioning system.

The UTR Steel Rotation Stages are compatible with UMR Steel Linear Stages, TGN Series Tilt Platforms, and MVN Precision Vertical Stages of matching size (for example, UTR80 with UMR8.25 and TGN80 , or UTR120 with TGN120 and MVN120). They can be combined to provide multi-axis motion and can be easily adapted to fit a specific system's needs. In the picture, a six-axis manual positioning system is shown using two UMR8.25s, two TGN80s, a UTR80S, and a MVN80. (Hint: first assemble Y & Z stages from the backside of Y stage, and then connect X stage to YZ from backside of X. In both steps, the carriage of UMR stage needs to be translated to each end of the travel range to reveal access holes, please refer to UMR stage XY assembly video.)
