The RSP1 rotational stage utilizes two precision bearings for smooth backlash-free rotation. The center aperture accepts 1" diameter optics which are securely held in place by a threaded retaining ring. The knurled edge of the RSP1 allows fine angular adjustment. The position is indicated on a 360° scale which has been graduated into 2° increments. #8-32 (M4) Mouting hole, compatible with our SM1LXX Series stackable lens tubes.

The RSP1 rotation mount utilizes two precision bearings for smooth backlash-free rotation. The center aperture, threaded with our standard SM1 thread, accepts Ø1" (25.4mm) diameter optics which are secured in place with a SM1RR threaded retaining ring (one included with RSP1). The knurled edge of the RSP1 and 360° laser engraved scale marked at 2° increments allows for precise, repeatable positioning and fine angular adjustment. A convenient top-located set screw secures the rotational position of the stage.
