Rotation Stage

   The RSF-1 is ideal for positioning 1.0 inch polarizing optics, or for rotating beam splitters and prism cubes.  This high precision ball-bearing rotation stage combines 360° of coarse positioning with ±10° of manual adjustment using our 100TPI adjustment screw which enables 5 arc-minute resolution, 5 arc-second minimum controllable motion.  For applications requiring hands off adjustment the manual adjustment can be replaced with a 421 or 841 actuator for remote motorized positioning.
   Mounting in the vertical (rotation along the optical axis) is achieved by attachment to one of the two 8-32 (M4) tapped holes on the perimeter.  These attachment points put the adjustment screw in the vertical or horizontal plane.  For horizontal applications (rotating beam splitters and prism cubes perpendicular to the optical axis) the stage can also be mounted on our RSF-HA horizontal adapter.
   The face of the RSF-1 includes four 8-32 (M4) and four 1⁄4-20 (M6) tapped holes for accommodating a wide variety of devices to be rotated.  The 11⁄16-20 I.D. thread (accommodates 1.0 inch optics) is supplied with two Delrin® retaining rings for securely holding delicate optics without damage.
