The HDR50(/M) Heavy-Duty Rotation Stage provides motorized, continuous rotation and can support loads up to 50 kg (110 lbs). It incorporates a micro-stepping motor, worm gear assembly, precision bearings, and a low-profile design with a height of 44.0 mm. The central aperture features an SM2 thread on the rotating and the non-rotating parts, making the stage compatible with our SM2 lens tubes. The stage has four 1/4" (M6) countersunk holes that allow it to be secured directly to a breadboard. The holes are spaced apart such that an imperial stage may also be mounted to a metric breadboard and vice versa. The stage can also be post mounted using the six 1/4"-20 (M6) side-located mounting holes.

Accessories
We offer several types of top plate adapters which mount to the rotating world of the HDR50(/M) stage using 8-32 (M4) screws. We also offer two mounting adapters: the NR360SP2 bracket is designed for secure vertical mounting of the stage and the NR360SP5 adapter enables the HDR50 rotation stage to be mounted to select translation stages.

Software
This stage can be operated with the user friendly Kinesis software package, which allows the user to quickly set up complex move sequences. It also features .NET controls which can be used by 3rd party developers working in the latest C#, Visual Basic, LabVIEW™ or any .NET compatible languages to create custom applications. All relevant operating parameters are set automatically by the software for Thorlabs stage and actuator products. For more details, please see the Kinesis Software and Kinesis Tutorials tabs.

Thorlabs' Kinesis^® software can be used to control devices in the Kinesis or APT™ family, which covers a wide range of motion controllers ranging from small, low-powered, single-channel drivers (such as the K-Cubes and T-Cubes) to high-power, multi-channel, modular 19" rack nanopositioning systems (the APT Rack System).

The Kinesis Software features new .NET controls which can be used by 3rd party developers working in the latest C#, Visual Basic, LabVIEW™ or any .NET compatible languages to create custom applications. Low level DLL libraries are included for applications not expected to use the .NET framework. A Central Sequence Manager supports integration and synchronization of all Thorlabs motion control hardware.

By providing these common software platforms, Thorlabs has ensured that users can easily mix and match any of the APT and Kinesis controllers in a single application, while only having to learn a single set of software tools. In this way, it is perfectly feasible to combine any of the controllers from the low-powered, single-axis to the high-powered, multi-axis systems and control all from a single, PC-based unified software interface.

The software packages allow two methods of usage: graphical user interface (GUI) utilities for direct interaction with and control of the controllers 'out of the box', and a set of programming interfaces that allow custom-integrated positioning and alignment solutions to be easily programmed in the development language of choice.

Thorlabs' Kinesis^® software features new .NET controls which can be used by third-party developers working in the latest C#, Visual Basic, LabVIEW™, or any .NET compatible languages to create custom applications.

C#
This programming language is designed to allow multiple programming paradigms, or languages, to be used, thus allowing for complex problems to be solved in an easy or efficient manner. It encompasses typing, imperative, declarative, functional, generic, object-oriented, and component-oriented programming. By providing functionality with this common software platform, Thorlabs has ensured that users can easily mix and match any of the Kinesis controllers in a single application, while only having to learn a single set of software tools. In this way, it is perfectly feasible to combine any of the controllers from the low-powered, single-axis to the high-powered, multi-axis systems and control all from a single, PC-based unified software interface.

For a collection of example projects that can be compiled and run to demonstrate the different ways in which developers can build on the Kinesis motion control libraries, click on the links below. Please note that a separate integrated development environment (IDE) (e.g., Microsoft Visual Studio) will be required to execute the Quick Start examples. The C# example projects can be executed using the included .NET controls in the Kinesis software package (see the Kinesis Software tab for details).

LabVIEW
LabVIEW can be used to communicate with any Kinesis- or APT-based controller via .NET controls. In LabVIEW, you build a user interface, known as a front panel, with a set of tools and objects and then add code using graphical representations of functions to control the front panel objects. The LabVIEW tutorial, provided below, provides some information on using the .NET controls to create control GUIs for Kinesis- and APT-driven devices within LabVIEW. It includes an overview with basic information about using controllers in LabVIEW and explains the setup procedure that needs to be completed before using a LabVIEW GUI to operate a device.

What is the IP-rating of the HDR50?

cwright (posted 2020-11-03 08:25:25.0)

Response from Charles at Thorlabs: Hello and thank you for your query. Our stages are designed to be used within an indoor lab environment and so have not been tested for ingress protection. We will reach out to see if we can advise on suitability for your application.

Warren Massey (posted 2020-05-22 07:12:03.84)

The manual says that the homing/limit sensor is a 5VDC Hall switch and that the signal line from the switch is pin #3 on the 15-pin connector. What is the part number of that hall switch? When the stage is at its home position and the switch is in its active state, is pin #3 grounded or at 5 volts?

Dear Concern, I have an inquiry regarding HDR50/M. We are plan to use HRD50/M for our ellipsometry project for polarizer and analyzer. Is that stepper motor have Zero position option. What do you mean by Homing Bidirectional Repeatability in the specification? Thank you Rashed

cwright (posted 2020-01-07 09:16:27.0)

Response from Charles at Thorlabs: Hello Rashed, the repeatability specification is a measure of a stage's ability to return to a commanded position. i.e. how close it will be to the original position. Bidirectional repeatability is an average of the repeatability when the commanded position is approached from both directions and is regarded as a more descriptive way of specifying repeatability. Thorlabs specifies this value as the bidirectional repeatability with backlash correction enabled. The homing bidirectional repeatability is the bidirectional repeatability the stage can achieve when finding it's zero (home) position. "Is that stepper motor have Zero position option." I am unsure what you are referring to here so I will reach out to you directly to discuss your requirements.

Hi, Is it possible to control the NR360S stepper motor with a brushed Motor Controller? I am unable to control the motor with the kinesis software. Thanks, Charles

AManickavasagam (posted 2019-07-25 04:59:03.0)

Response from Arunthathi at Thorlabs: Thanks for your query. Since the NR360S is a stepper motor it would not work with a brushed motor controller. You would need to use a stepper motor controller such as the BSC201 (https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1704&pn=BSC201). We will contact you directly to troubleshoot the issue you have with Kinesis.

Could you clarify the differences of HDR50 compared to the previous NR360S stage? I'm wondering why a different product was introduced (the specs look very similar to me).

AManickavasagam (posted 2019-06-10 06:16:53.0)

Response from Arunthathi at Thorlabs: Thanks for your query. The NR360 is redesigned as HDR50 having performance specs with higher certainty level and for repeatable production process.

user (posted 2019-05-09 16:17:04.293)

New products keep coming from Thorlabs, yet they cannot be used in environments where DUT requires a specific OS. Since DUT and equipment must share the same computer for automation, if equipment presents a limitation such as being locked to a specific OS, then DUT that requires a different OS cannot be tested on such station. Thorlabs fails to provide a simple OS agnostic API. Thorlabs equipment cannot be used on macOS, thus cannot be incorporated into large testing stations. Thorlabs claims that they do provide API for their controllers, but it's like a 400+ page technical document encompassing low level serial interface commands, rather than a high level simple API. Good luck understanding how to program using this low level API, I'd bet you'll spends months perfecting it.

Response from Ben at Thorlabs: Thank you for your feedback. We value your thoughts, which I’ve referred onto my colleagues at our Motion Control Engineering site. We are actively improving our Kinesis Motion Control software platform with regular updated releases. As you’ve identified, currently our high level Kinesis .NET and C APIs are targeted for use with modern Windows Operating Systems. For users wanting to connect with devices on non-Windows operating systems, we offer access through a low level communications protocol detailed in a comprehensive .pdf document found on our website. This is targeted at experienced developers and lists all available methods documented with code examples as well as details of device enumeration and device unit conversion. Should you need any assistance with interpreting the document you are welcome to contact your local Technical Support office. We hope to provide API support at higher level entries across multiple operating systems in the future.

Dear Sir or Ma'am, Similar to a previous post, can you provide me some insight on how to accurately set the position of the NR360S (since it doesn't have an encoder)? I am not using the apt controller but rather a third party driver being controlled via labview. Thank you. Regards, Kevin

AManickavasagam (posted 2017-09-13 08:38:54.0)

Response from Arunthathi: Thank you for your question. In the NR360S with the stepper motor actuator, the position is determined by the number of steps taken by the stepper motor, which would be indicated by the controller. You can then calculate the degrees the platform has moved as each microstep equates to a movement of 13.3 x 10-6 micro-degrees. We strongly recommend to use our BSC stepper motor controllers to attain reliable accurate set positions.

We would like to use an NR360S/M in a remote positioning application, but it is critical that the required final position is reached (to avoid collisions with other moving parts). As there is no built - in position encoder, can you supply (or suggest) any other suitable method? e.g. a stepper motor with encoder, or an external encoder which could be fitted? Thanks in anticipation. John.

msoulby (posted 2014-07-02 09:47:55.0)

Response from Mike at Thorlabs: There is no direct way to attach two NR360S rotation stages concentrically, however without knowing more about your application I am not certain what benefit there would be by mounting two rotation stages on top of each other, if you can provide us with an email address or contact details we would be happy to discuss your application in more detail with you. Also the stage can operate mounted on its side or upside down, however we would advise caution to avoid overloading the stage. All of our specs are for horizontal, on axis, loads and can take up to 50kg in this configuration however we do not currently have any data for the load capacity for using the stage upside down.

msoulby (posted 2014-03-24 09:50:20.0)

Response from Mike at Thorlabs: The NR360S can handle an on axis load of up to 50kg when mounted horizontally. We do not specify for using off axis loads or torques but the stage can certainly handle 3-4 kg on a lever arm of about 25m lon.

msoulby (posted 2013-10-28 07:48:00.0)

Response from Mike at Thorlabs: It is possible to use the trigger pins on the control I/O connector on the rear panel of the stepper controller to make the stage respond to an external trigger. The stage can be set to make an absolute or relative move in response to the input trigger. The trigger settings can be accessed from the APT user settings or by using the ActiveX method SetTriggerParams.

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.

czl0579 (posted 2012-09-02 17:14:48.0)

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.

Tyler (posted 2008-06-13 08:43:14.0)

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.
