Our vacuum-compatible stainless steel rotation stages are made for use in 1E-6 Torr vacuum or clean room environments and are available in 40- and 60mm diameter platform sizes. They are driven by a special vacuum compatible micrometer which yields angular position readable to less than 2 arc minutes using the Vernier scale. Like all micrometer driven rotation stages, they are designed to provide full 360-degree coarse as well as short-range fine angular travel over a single rotational degree of freedom, most commonly yaw.
The axis of rotation is orthogonal to the mounting platform. These vacuum compatible rotation stages have vented attachment holes and are lubricated with a high-grade vacuum grease (YVAC2).
The KSPS-406M (40mm diameter) and the KSPS-606M (60mm diameter) Stainless Steel, lapped-surface bearing rotation stage are low profile rotation stages which offer coarse rotation adjustment of 360° and fine adjustment (with either a micrometer head or fine-pitch screw).
Directly rotate the stage upper plate for coarse adjustment, then clamp the clutch screw and use micrometer head or fine-pitch screw (±5°) for fine adjustment.
