Thorlabs' Manual Rotation Stages are cost effective platforms for an optomechanical component requiring smooth, backlash-free rotation. Each stage offers 360º of continuous rotation with a Ø1", Ø1.4", Ø2", or Ø4.3" mounting platform and utilizes needle roller thrust bearings for higher load capacities. An engraved angular scale along the edge of each stage's rotating platform allows the user to set the angular orientation of the stage. Rotation of the platform can be locked by tightening the side-located setscrew. Four corner-located counterbored holes are spaced for direct fastening to an optical table or breadboard.

Tholabs also offers a selection of other manual stages that are micrometer driven, have central through holes, or have built-in hard stops. For our entire selection of rotation stages, please see the Rotation Mounts and Stages tab.

Is it acceptable to mount a horizontal one sided setup on RP01 and RP03? I expect less than 10Nm torque and 2kg, but the center of gravity will be about 0.5m away from the rotation axis.

Hello, thank you for contacting Thorlabs. 0.5m is a much longer lever arm than we use to test the vertical specs. I will reach out to you directly to discuss your application and how to reduce that torque.

This product completly meet my need, however I think it would be usefull to add in the product description the size of the balldriver neeed to lock the platform. I had a bad surprise when I discivered that I had to make a second comand to get a balldriver of the correct size.

Hello, thank you for your feedback. I'll ask our Marketing team to add the 5/64" size of the ball driver to the web presentation.

Rotation Mount and Stage Selection Guide

Thorlabs offers a wide variety of manual and motorized rotation mounts and stages. Rotation mounts are designed with an inner bore to mount a Ø1/2", Ø1", or Ø2" optic, while rotation stages are designed with mounting taps to attach a variety of components or systems. Motorized options are powered by a DC Servo motor, 2 phase stepper motor, or an Elliptec™ resonant piezo motor. Each offers 360° of continuous rotation.

Load Capacity: 40 lbs (18 kg) with Stage Mounted on a Horizontal Surface
Four 1/4" (M6) Clearance Holes to Mount to Optical Tables or Breadboards

Thorlabs' RP005(/M) Manual Rotation Stage has a Ø1" rotating platform and is ideal for smaller optomechnical components requiring smooth, backlash-free rotation. The stage offers 360º of continuous rotation with a scale that is engraved in 2° increments along the side of the rotating platform. The scale is marked every 30° by a number directly under its corresponding tick mark. Rotation can be locked by tightening the side-located setscrew using a 5/64" (2.0 mm) balldriver or hex key. Do not remove the locking setscrew from the stage; doing so can permanently reduce locking performance.

The rotating platform contains six 4-40 (M3) taps, for smaller components such as cage cube optic mounts or mini-series posts, and one, central 1/4"-20 (M6) tap for larger components such as Ø1/2" or Ø1" post assemblies. Additionally, the top platform includes two Ø0.13" holes for mounting Thorlabs' FiberBench optic mounts, wave plate modules, polarization modules, and alignment tools. A setscrew with a 0.05" (1.5 mm) hex on the side of the rotating platform locks the FiberBench accessory in place.

Four 1/4" (M6) clearance holes are included in the base to mount the stage to an optical table or breadboard. When mounted on a horizontal surface, the stage can support a load up to 40 lbs (18 kg).

Thorlabs' MSRP01(/M) Manual Mini-Series Rotation Stage has a Ø1.4" rotating platform and provides smooth, backlash-free rotation utilizing two precision bearings. The stage offers 360º of continuous rotation with a scale that is engraved in 2° increments along the outer circumference of the rotating platform. It is marked every 20° by a number directly under its corresponding tick mark and includes a 20 arcmin Vernier scale. Rotation can be locked by tightening the side-located setscrew using a 0.05" (1.3 mm) balldriver or hex key.

The rotating platform contains four 4-40 (M3) taps and one central 8-32 (M4) tap for mini-series posts and accessories or our miniature dovetail stages, as shown in the image above.

Four #4 (M3) clearance holes are included in the base to mount the stage to a mini-series breadboard. A side-located 4-40 (M3) mounting hole is included to mount the stage vertically. It has a maximum torque capacity of 1.3 N·m when mounted in this configuration. When mounted on a horizontal surface, the stage can support a load up to 50 lbs (22 kg).

Four 1/4" (M6) Clearance Holes to Mount to Optical Tables or Breadboards

Thorlabs' RP03(/M) Manual Rotation Stage has a Ø4.3" rotating platform and is ideal for larger optomechnical components requiring smooth, backlash-free rotation. The stage offers 360º of continuous rotation with a scale that is engraved in 1° increments along the outer circumference of the rotating platform. It is marked every 20° by a number directly under its corresponding tick mark. Rotation can be locked by tightening the side-located setscrew using a 5/64" (2.0 mm) balldriver or hex key.

The imperial RP03 rotating platform contains eight 6-32, sixteen 8-32, and thirteen 1/4"-20 taps. The metric RP03/M rotating platform contains twenty-four M4 and thirteen M6 taps. The 6-32 taps can be used with our PM3 and PM4 Clamping Arms, while the M4 taps can be used with our PM3/M and PM4/M Clamping Arms. This allows you to clamp small to large componens onto the rotating platform, as shown in the image above and to the right. The 8-32, M4, 1/4"-20, and M6 taps can all be used to secure larger systems, such as a manual or motorized translation stage or post assembly.

Four 1/4" (M6) clearance holes are included in the base to mount the stage to an optical table or breadboard. Three side-located 8-32 (M4) mounting holes are included to mount the stage vertically. It has a maximum load capacity of 50 lbs (22 kg) when mounted in this configuration. When mounted on a horizontal surface, the stage can support a load up to 175 lbs (79 kg).
