Rotation Stage, 360° Coarse, 5° Fine, Includes Adjustment Screw, 8-32 and 1/4-20

The 481-A-S Rotation Stage is ideal for fine 5° tuning the angular orientation of any component after rotating it to an approximate angle. An inner stage rotates 360° in a precision bored bushing that locks with a side mounted thumbscrew. The outer stage is a high resolution, tangentially driven design. Scale markings indicating every degree and a vernier with 5 arc min markings are engraved on the side of the stage. The 481-A-S uses 100 pitch AJS Fine Adjustment Screws for high resolution and attaches to tables and breadboards via clearance slots in the base, and to posts using one of two tapped holes located in the side of the stage. Additionally, the 481-A-S includes two 1 inch (25.4 mm) diameter retaining rings and a solid aperture insert with a centered clearance hole for on-axis mounting of components such as post holders.
