The UTR-A series rotation stages provide the same versatile capabilities as the UTR series, which include course/fine travel of 360°/4° available in multiple sizes and high load capacity, while also having a center aperture, making them ideal for a wide range of optical systems such as microscopy.
Center aperture for collinear optical access
Robust steel construction for high load capacities
M- metric versions have the same specifications as the imperial versions shown.
The UTR46SA low profile version has a 23 mm height, and a 22 mm aperture.
M- metric versions have M4 threads where 8-32 is shown and M6 threads where 1/4-20 is shown.
Features
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.
Center Aperture For Collinear Optical Access
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.
Versatile Configuration Options for a Range of Applications
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.
Easily Combined for Multi-axis Motion
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.)
Steel Construction Provides High Load Capacity & Smooth Rotation
The UTR stages are made of stainless steel to provide a robust frame with centered load capacities up to 800 N. Bearings are preloaded into precision-ground, tool steel races for a smooth, accurate trajectory with minimum eccentricity.
