Manual 360° Rotation Stage with Two Hard Stops




  • Continuous 360° Rotation with Two User-Positionable Hard Stops
  • Ø2" Mounting Platform with an Array of Tapped Holes
  • Precise, Submicron Repeatability(<15 µrad )

Features

  • 360° Rotation with Two User-Positionable Hard Stops
  • Quick, Highly Repeatable Rotation of an Optic or Optical Device
  • Load Capacity: 75 lb (34 kg) with Stage Mounted on a Horizontal Surface

The QRP02(/M) Rotation Stage offers 360° of continuous manual rotation with two user-positionable hard stops. The first hard stop can be positioned to coincide with any of the eight 4-40-tapped holes located at 45° intervals in the base. The stop's position is set using a threaded alignment pin that is secured with a 5/64" (2 mm) hex key. The second hard stop is an alignment pin attached to a rotating section under the mounting platform. It can be positioned anywhere along the 360° range of motion and locked into place by tightening the setscrew to the left of the dowel using a 5/64" (2 mm) hex key.

The rotation platform is secured to the hard stops by a double-sided magnetic tab and can be moved between them with

The Ø2" (Ø50.8 mm) mounting platform includes an array of 1/4"-20 (M6), 8-32 (M4), and 6-32 (M4) tapped holes for mounting optomechanical components, including our PM3 and PM4 clamping arms. The base is equipped with 1/4" (M6) counterbores on 2" (50 mm) centers to enable optical table or breadboard mounting. Additionally, the rotation mount's base can be mounted at any angle of rotation using the side relief cuts and our CL6 or CL8 clamps, allowing for the arbitrary positioning of both hard stops (see photo below, right).

This stage offers a 75 lb (34 kg) load capacity when mounted on a horizontal surface. When mounted on a vertical surface, a torque up to 2.5 lb·ft (3.4 N·m) can be applied about an axis orthogonal to the rotation axis. In testing, a 20 lb (9.1 kg) load was placed 1.5" (38 mm) from the mounting surface, at the center of the platform.
