Thorlabs' NRT150(/M) Linear Positioning Stage is optimized for applications requiring high load capacity and high resolution, such as measurement and inspection. It provides 150 mm of linear travel for loads as great as 20 kg (44 lbs) when mounted horizontally and 5 kg (11 lbs) when mounted vertically. Each stage features a typical on-axis accuracy of 2.0 µm (5.0 µm Max) when the included calibration files are used with the APT™ software. The lead screw, directly driven by a two-phase stepper motor with 409,600 microsteps per revolution, provides smooth translation with a theoretical positional resolution of less than 100 nm. Due to the stepper motor design, the platform position remains fixed when no power is supplied to the stage, unlike with DC servo motor translation stages.

The main platform is supported by four recirculating ball carrier bearings mounted to precisely aligned linear guide rails. The stepper motor, specifically designed for microstepping applications, allows smaller and smoother low-speed motion with significantly reduced vibrational noise than DC servo motors. The choice of a trapezoidal lead screw provides a number of benefits over the more common Acme-style thread, including improved durability, lower friction due to improved surface quality, and very little backdrive, eliminating the need for the braking mechanism required with ball screws.

Calibration Files
Each NRT150(/M) Linear Translation Stage is calibrated during manufacturing. Calibration enables the controller to correct for any mechanical errors present in the system. Mechanical components, such as the lead screw and linkages, can be machined only within a certain tolerance. These mechanical errors result in deviations of the actual position from the commanded position. However, the deviations are repeatable and can be compensated for using the APT software and included calibration files. These files are used by the APT software to convert the position entered by the user into the required mechanical motion. The calibration files can be downloaded by clicking on the red Docs icon () next to the item # below and entering your device's serial number under "Download Calibration Data."

The use of calibration files is optional. Without installing a calibration file, the on-axis accuracy of a stage will fall from 2.0 µm (typical) to 19.29 µm (typical). Calibration files do not affect the repeatability and resolution of the stages.

Stage Combinations
If an XY configuration is desired, any combination of NRT150 and NRT100 Linear Positioning Stages (the latter features a 100 mm travel range) can be mounted directly atop one another by using 1/4"-20 (M6) cap screws together with the provided counterbored holes and slots. These counterbores are accessed through the Ø0.59" (Ø15.0 mm) clearance hole in the moving carriage. XZ and XYZ configurations are possible using our NRT150P1(/M) Vertical Mounting Bracket, which orients either an NRT100 or NRT150 in the vertical plane.

Controller Options
A Thorlabs benchtop stepper motor controller, available in one-, two-, or three-channel versions, is required to drive this 150 mm translation stage. These controllers are bundled with Thorlabs' apt™ software, which supplies out-of-the-box stage control from a PC and enables support for common programming interfaces like LabVIEW, LabWindows™, and ActiveX. This stage is also compatible with third-party controllers.

The APT™ (Advanced Positioning Technology) family covers a wide range of motion controllers ranging from small, low-powered, single-channel drivers (such as the T-Cubes) to high-power, multi-channel, modular 19" rack nanopositioning systems (the APT Rack System).

All controllers in the APT family share a common software platform, the 'APT System Software', which is available on our APT software download page. A support package, containing a wealth of information on using and programming these Thorlabs products is also available.

By providing this common software platform, Thorlabs has ensured that users can easily mix and match any of the APT 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 APT System Software allows two methods of usage: graphical user interface (GUI) utilities for direct interaction 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.

A range of video tutorials are available to help explain our APT system software. These tutorials provide an overview of the software and the APT Config utility. Additionally, a tutorial video is available to explain how to select simulator mode within the software, which allows the user to experiment with the software without a controller connected. Please select the APT Tutorials tab above to view these videos, which are also available on the software cd included with the controllers.

Hi, We already have an installed NRT150/M stage, and we are planning to wire it to a 3rd party controller. Can you tell me what the normal state of the active limit switches are when powered by the 5V? Normally open or normally closed? Thanks, Matthew
bwood  (posted 2018-02-05 05:25:32.0)
Response from Ben at Thorlabs: Thank you for your feedback. The limit switches are in a open collector and have a pull up on the stage. When the limit switch is activated the output pulls down to ground. When the limit switch is not activated the limit switch output is at 5volts. Looking at a BSC201 with this stage connected the limit switches are set to ‘switch makes’ so you can argue they are normally open and go closed on active

How could a rigid stand (MP100) be mounted to this stage? I assume this will require some kind of intermediate adapter, as the counterbores of the MP100 have a 3x2" layout, while the NRT150 has a 2x2" moving surface)

Response from Arunthathi at Thorlabs: Thank you for your query.Unfortunately, the NRT150/M's plate is not large enough to mount MP100. However, you could use the LTS150/M which also is a stepper motor based stage and will have similar performance as the NRT150/M.

Hi, We have recently purchased a LTS150/M. However, I have some problems installing the calibration file. When I enter the APT Config the stage does not show up under the Stage Tab and rather than the 'stepper' dropdown selection box as described in the manual I have a 'motor' drop down box. When I try to assign a calibration file (motor set to none) I get the error message "Stage type selected is not compatible with selected driver. Please select stage type not prefixed by LTS or HTS LTS". I would greatly appreciate any help. Best, Anna

Hi, I am interested in the NRT 150 but I'm not sure I read the specs correctly. The displacement error once calibrated is "Calibrated Absolute On-axis Accuracy" and is around 2 microns right ? Isn't that weird that the minimum displacement is 0,1 micron then ? As for the velocity, "Velocity Stability ±0.1 mm/sec" means 0,1 mm/s is the slowest reliable velocity I can set ? Thank you.
msoulby  (posted 2013-10-17 12:25:00.0)
Response from Mike at Thorlabs: I will try to clarify what the specifications mean. Minimum incremental motion: This is the actual minimum incremental motion that a stage can make, otherwise known as the minimum step size. This is calculated based on the minimum step size of a motor and the gearing in the stage. Typically the theoretical step size is smaller than actual achievable step size as there are several other factors such as friction, load, external forces, vibrations, type of controller and inertia. This has nothing to do with how accurate the stage is only what the smallest repeatable step size we can achieve is. On axis accuracy: This is the absolute accuracy of the commanded position. It is defined as the maximum discrepancy between command position and absolute position over the full travel of the stage and should not be confused with repeatability. For example if a stage is specified with an on axis accuracy of 2µm then a command to travel to 10mm will result in an absolute position of within 2um of 10mm. This value will tell you the maximum possible inaccuracy at any point in your travel. However, sometimes a more useful specification can be maximum percentage accuracy as the discrepancy between command position and absolute position generally increases linearly with the amount of travel. This gives rise to an on axis accuracy which is generally much less than the accuracy at the beginning of the travel of the stage. The percentage accuracy can give you a good idea of what to typically expect along the stages travel. The velocity stability was measured when the stage is moving at the maximum velocity and we will clarify this on the website, therefore this means that the maximum velocity is 30.0mm/s +/-0.1mm/s. the lowest velocity that can be entered for these stepper motors is around 40um/s which is limited by the controller code and software. You should also note that as these stages use a two phase stepper motor then low velocities could result in a jumpy, unstable velocity as the motor rotates and switches between each motor phase. For a more stable velocity you would need to use a 5 phase stepper motor, which thorlabs does not currently offer, or one of our direct drive linear stages such as the Thorlabs DDS220.

Our NRT150 keeps showing that it reaches forward hardware limit no matter where it is. How to fix that?

Response from Javier at Thorlabs to fg2251: Thank you very much for contacting us. We are currently developing an optical delay line kit which will be released later this month. This kit includes a 220 mm direct travel stage (DDS220, link below), a DC Servo controller, control software and extended programming through ActiveX controls, and all opto-mechanics including the periscope assembly. The minimum incremental motion is 0.1 um for your 100 fs delays. The pitch gives you the angular runout. For the DDS220 stage, 0.01 degree pitch will give you at least a 30um displacement. DDS220 and BBD101: http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=5305&pn=DDS220#5305 We will contact you directly for further support.

I am interested to the 150mm linear stage NRT150 My application is to build a delay line in a fs pump probe experiment. My pulse duration is 100fs so I need a minimum motion on the order of 15micron I need to delay the pump beam that after the delay line will be focused on spot of 50-500micron, so the angular as well linear deviation from straight line motion is critical for me. I want some information: Absolute on axis accuracy is 20micron. Is it referred to a motion of 150mm? How much the cost will be with the calibration? What about the linear and angular runout? Is it the pitch and Yaw? Do you have other suggestion for my application? Can you provide the stepper controller with labview software for integration on my setup (lock in amplifier, DAC..)? Let me know Felice

A response from Jonathan to cjc16: Im afraid we wont be able to offer this. You could try doing this work youself, but the hall effect switchs are set to give the correct position.

I have purchased an NRT150 and I am in the process of wiring it to be compatible with our drive system. I found that you are using proximity switches that require 5v power but we typically use NC mechanical switches with our hardware. Do you have an option to retrofit mechanical switches in place of the proximity switches?
klee  (posted 2009-09-14 17:18:57.0)
A response from Ken at Thorlabs to jbotha: The bearing can take 18.7Nm moment in x (longitudinal, direction of travel) and 18.7Nm in y. There are two, so the shift of where the moment is actually pulling is quite complicated but it should be fine as you wont get a 90/10 split in how the load is distributed. Becuase of the unusal angle of the force on the lead screw you might have to reduce velocities but it should be fine.

Hi, Very much interested in you NRT150-product. I do have the following question which will determine whether or not this product is suitable for our application which I could not find among your specifications listed: What is the maximum permissible moment allowed on the sliding table of the NRT150? The application we want to bolt on to the sliding table has an offset center of gravity which will exert a maximum of 20 Nm around the longitudinal axis and 10 Nm around the transverse axis. Thank you in advance for your assistance! Kind regards, Jan Botha

A response from Tyler at Thorlabs to Ian: 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 translation stage.

Is the carriage shown 75mm from the central position on the drawing? There are no dimensions from the carriage to the end of the stage. It would be helpful to know where the limits are.
