Motorized Rotation Stage

The compact size and high performance of our RSA-1.0i motorized rotation stage makes it ideal for motorized rotation applications in the laboratory as well as OEM systems. By employing our standard DC servo motor, the
overall thickness of the base is minimized to 1.0-inch (25-mm). Standard mounting features include both 1⁄4-20 and M6 tapped holes on two edges for post or AS spacer mounting with the axis of rotation horizontal. Additionally, universal slots (U.S. system and metric spread) are included for attachment directly to a isolation table or platform with the axis of rotation vertical. The 1.0-inch inner diameter of the rotating dial accepts common 1.0-inch and 25-mm optics and is supplied with two Delrin® retaining rings. The dial has six tapped holes (3 each 8-32 and M4) on the face to attach other optical or mechanical elements.

Adapter for RSA-1.0i

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.

■ Quiet running DC servo motor

■ Positive worm gear drive

■ Flexible mounting features
