Rotary Stages

   RS series rotation stages provide smooth, continuous angular positioning for a variety of components.  Both sizes of RS series rotation stages use our unique integrated bearing design.  This ball bearing design is a robust but cost effective alternative to more expensive bearing packages.  Our knurled drive system coupled with the bearing system ensures smooth positioning throughout the full 360° of continuous rotation.

   The knurled edge of the rotating platform gives convenient coarse positioning control.  A fine adjustment knob controls angular positioning through a 360° scale graduated in 2° increments.  The rotating platform can be securely locked in position by a non-influencing lock that is integrated into the fine adjustment knob.

   RS series rotation stages are available in two styles:  aperture (RSA-1.0 and RSA-2.0) for polarization applications and solid platform (RSX-1.0 and RSX-2.0) for mounting prisms, mirrors, and stages.  Aperture versions come with two Delrin ® retaining rings to securely hold optics without damage.  The solid platform versions have a 1⁄4-20 tapped hole at the center of rotation and all models have six 8-32 tapped holes for added mounting flexibility.  For vertical mounting there are 8-32 (RSA-1.0 and RSX-1.0) and 1⁄4-20 (RSA-2.0 and RSX-2.0) tapped holes on the edge of the stage.  Horizontal or table top mounting is accomplished through two 1⁄4-20 clearance holes at opposite corners of both sizes.

Adapter for RSA-1.0      The RS-1.0i threaded adapter provides a change from a 11⁄16-20 internal thread to a 1⁄4-20 (M6) thread.    Also used on Model OG-1.0P series, polarizing gimbal mount.
