The NR360S rotation stage provides arcsecond resolution when driven from a micro-stepping stepper motor controller, such as the BSC20x Series. The low-profile design has a height of just 55 mm due to the use of two compact precision bearings. The rotating carriage of the stage allows continuous rotation and can support loads up to 50 kg. The aperture through the center of the rotation stage features an SM2 thread on the rotating and the non-rotating parts, making the stage compatible with our SM2 range of lens tubes and optics.

The frame of the stage is made from aluminum and has four 1/4" (M6) countersunk holes that allow the stage to be secured to a translation stage or optical table using one of the adapter plates presented below. In addition, four M6 tapped mounting holes are located on the sides of the stage to provide additional mounting options. A worm gear assembly transfers the rotary motion of the stepper motor into rotary motion of the carriage. The mechanical reduction in this gear assembly provides one revolution of the carriage for every 66 turns of the stepper motor.

We encourage you to review the tabs above for detailed specifications of the NR360S and the recommended Stepper Motor Controller, the BSC200 Series. Please note that Thorlabs offers bottom mounting adapter plates and brackets to secure the NR360S as well as several types of rotating adapter plates; these items are featured below with more detailed product descriptions.

The BSC100 Series apt™ controller is a range of single, two and three channel 50 W stepper motor controllers designed to drive high power, 2-phase bi-polar stepper motors, with and without encoder feedback. It is the recommended driver for the NanoRotator 360 Degree Rotation Stage (NR360S). The unit is designed to drive not only nano-positioning actuators and stages, but also any generic two phases bi-polar motor of varying powers and varying cardinal step sizes (a breakout cable is available to support this latter option).

USB connectivity provides easy plug-and-play PC operation - multiple units can be connected to a single PC via standard USB hub technology for multi-axis motion control applications. Coupling this with the very user friendly apt™ software allows the user to very quickly get up and running with reasonably complex move sequences in a short period of time – for example, all relevant operating parameters are set automatically for Thorlabs stage/actuator products, such as the NR360S.

Response from Jeremy at Thorlabs: The holding torque is the torque keeping the motor static. Please note that the 23.1N-cm spec is the holding torque spec for the motor only. The load capacity when the NR360S is mounted vertically is around 10kg. 90Ncm would be around the maximum that you should put on the stage.

How do you define the holding torque of the stage? We vertically mounted the stage and applyed 90Ncm torque onto it. The stage seems can still handle it. What is the load capacity perpendicular to rotation axis?

Response from Tim at Thorlabs to quyngoc89: Accuracy is a measure of how well the stage will move to the intended position. Resolution is a measurement of the smallest amount the stage can be moved.

I looked at the specs sheet but I don't understand the different between the accuracy (5 arcmin) and the resolution (1 arcsec). Could you please explain it? Thank you.

What bending moment can the rotator manage? The application requires one rotator mounted horizontally, with a second rotator mounted vertically and offset from the first by say 0.5 meters horizontally and connected to the first rotator. The bending moment may reach 3 kg-m.

Response from Javier at Thorlabs to tlorentz: The NR360S is not designed for vacuum compatibility. The grease used in the stage is vacuum compatible, but the plastic and rubber components, and the anodizing, will in all likelihood outgass in vacuum levels higher than 10^-3 Torr.

How serious of a concern is outgassing with this product -- is it compatible with vacuum environments? e.g., up to 10^-3 torr, up to 10^-6 torr

A response from Greg at Thorlabs to cwliang: The resolution of the NR360S is derived from the micro step count of the motor itself as there is no rotary encoder incorporated within this rotation stage.

Hi there, The stage has a 1-arcsec resolution. Does this resolution came from the circular encoder readout or the step motor micro-steps counting?

Response from Tor at Thorlabs to Boris: You can expect < 50 um for the NR360S. We are working on providing more specs for this stage in the near-future.

Response from Javier at Thorlabs to khadock: The NR360S stage is suitable for operation in a class 1000 clean room environment. We would not recommend it for class 100 clean rooms, as outgassing might occur.

Is the NR360S rated for clean-room use?

A response from Adam at Thorlabs to Mathieu: The maximum static torque this stage can handle is 23.1Ncm. What type of torque will you apply? We are currently testing the dynamic torque, but would like to know you load specifications to better answer your question.

Poster: mathieu.gibert

Posted Date: 2010-01-28 18:27:02.0

What is the torque that this rotating stage can handle? -in static (I want it to stay in a particular angle but I apply a "constant" torque to it). -in dynamic (The applied "constant" torque is still present and I want the stage to turn to another specified angle) Thanks a lot in advance, Mat

A response from Ken at Thorlabs to skhan17: The apt software will show degrees of movement when using NR360S. Just make sure you choose the correct stage and controller in the APTConfig utility before you run the program.

Does the APT software that is included show degrees of movement when using NR360? Reading the Controller manual only shows movement in millimeters.

A response from Ken at Thorlabs to wu47: Yes, you can use LabView to control NR360S/M, but you will need the BSC101 controller as well . There are video tutorials available on our website. http://www.thorlabs.com/tutorials/APTProgramming.cfm

A response from Tyler at Thorlabs to Ian: The hole spacing is not symmetrical about the 50 mm center hole on the NR360S because the space occupied by the internal mechanisms prevented the symmetric placement of the mounting holes. The distance between the mounting holes of 101 and 51 allow the stage to be mounted on a metric or imperial optical breadboard with the use of an NR360SP1 spacer plate. In an effort to keep our drawings uncluttered enough to be readable we only display a limited number of dimensions. If the dimension you are looking for is not displayed you can contact an applications engineer at Thorlabs or load the ParaSolid, eDrawing, or Step file and measure the dimension using the softwares measurement tool. eDrawings is a free web browser download that can be used to view the ParaSolid and eDrawing files. I will have an applications engineer contact you to avoid confusion and make sure that you are getting the dimension that you have requested. Thank you for your interest in our rotation stage.

Please explain the rationale behind the hole centre spacing of 101mm and 51mm. Also, please confirm whether the 101mm spacing is symmetrical about the 50mm centre hole, and if not symmetrical, please advise what the offset is.
