Aperture Platform Rotation Stage, 2.65 in. Diameter, 10° Fine

The RS65 Rotation Stage provides precision rotation of components for laboratory, production, or industrial OEM applications. This aluminum stage rotates 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 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 RS65 allows 1 inch (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 RS65 is compatible with optical tables. A tapped hole is provided on the side for mounting this 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.
