Features
360° Coarse Rotation - 5° Fine Rotation
The 481 Rotation Stage series is ideal for fine-tuning the angular orientation of any component after rotating it to an approximate angle. The stages feature 360° continuous coarse translation on the precision bored bearing turned by hand and 5° fine adjustment tangentially driven by a micrometer or 100 TPI fine adjustment screw. To activate the fine adjustment, the coarse rotation needs to be locked in place with the thumbscrew. Scale markings indicating every degree and a Vernier with 5 arc min markings are engraved on the side of the stage.
Versatile Optic Mounting
The 481 Series Rotation Stages feature 1.063"-20 threaded central aperture which allows secure mounting of 1.0 in. optic such as waveplates and polarizers using included retaining rings, 0.5 in. optic in
Replaceable Actuators
The actuators of 481 Series Rotation Stages can be quickly removed by untightening the side clamping screw in the actuator mount, allowing the user to install another type of actuator which best fits the precision requirement of the application. The compatible actuators include adjustment screws of higher TPI such as
Easily Combined for Multi-axis Motion
The 481 High-Performance Rotation Stages are compatible with a variety of our linear stages and tip & tilt platforms. They can be combined to provide multi-axis motion and can be easily adapted to fit a specific system's needs.
