rotary stage, closed loop, 2.0" optic
Product Attachments

The compact size and high performance of our RSA-2.0i motorized rota­tion stage make 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 2.0-inch inner diameter of the rotating dial accepts common 2.0-inch and 50-mm optics and is supplied with two Delrin® retaining rings. The dial has twelve tapped holes (6 each 8-32 and M4) on the face to attach other optical or mechanical elements.
