Manual Rotation Stage, Steel, 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.

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 BR-U Mounting Bridle when the base plate cannot be used.

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.
