RS Series Rotation Stages provide precision rotation of components for laboratory, production, or industrial OEM applications. These aluminum stages rotate 360° in a precision bored bushing. By tightening a thumb screw on the side of the stage, the platform is tangentially driven by the precision actuator. The model RS40 includes a BM11.5 micrometer, while RS65 is supplied without an actuator to allow the user to choose between a fine adjustment screw, micrometer, differential micrometer, or a motorized actuator. A graduated scale marked in 2° increments indicate angular position and a vernier scale allows position readout to 12 arc min. Rotation can be locked to prevent accidental adjustment and reduce drift by tightening a second thumb screw on the side of the stage.The model RS65 allows 1 in. (25.4 mm) diameter linear polarizers, wave plates, calcite polarizers, and polarizing cube beamsplitters to be rotated with precision. The inside diameter of the mount is threaded 1.063-20. Two Delrin retainer rings are supplied to securely hold the optics. Thin optics can be held with one retaining ring on each side of the optic. The internal thread enables Newport Glan-laser calcite polarizers and CH Series cube beamsplitter holders, with the equivalent male thread, to be rotated in this stage.The mounting hole pattern for Model RS40 is compatible with other 40 mm size components, while RS65 is compatible with optical tables when using optional Slotted Bases. A tapped hole is provided on the side for mounting these rotation stages vertically on a post. The RS65 also includes a solid aperture insert with a centered clearance hole for on-axis mounting of components such as post holders.A 1/2 inch diameter polarizer or waveplate can be mounted to the RSP-1T mount using the PRA-05 Adaptor, which screws into the rotator's 1.063-20 thread. The PRA-05 Adaptor included a retaining ring.
