Newport 481-A rotary stage

Description

The 481-A 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 is micrometer driven 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 includes two 1 inch (25.4 mm) diameter retaining rings
A-1.25-1RR
and a solid aperture insert
RSA-1TI
with a centered clearance hole for on-axis mounting of components such as post holders.
