Product Description
RS Series Rotation Stages, guided by a precision bored bushing, rotate a full 360°. By tightening a thumbscrew on the side of the stage, the platform is tangentially driven by the precision actuator. 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.
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.
