Thorlabs' 50 mm Travel Motorized Translation Stages are designed for applications that require stability, long travel, and high load capacity. Horizontal and vertical loads up to 48 kg (105 lbs) and 10 kg (22 lbs) are supported, respectively. Each stage's moving platform is equipped with thirteen 1/4"-20 (M6) taps for compatibility with standard optomechanics.
The moving platform contains holes for alignment pins that ensure orthogonality when the stage is stacked with other stages or connected to our accessories. The rigidity of the thermally matched, all-steel construction, along with the heavy-duty cross-roller bearings, provides precision motion and long life, even in less-than-ideal conditions.
The LNR502(/M) non-encoded translation stage offers a minimum repeatable incremental movement of 1 µm and ±3.9 µm of bidirectional repeatability. For even more precise movement, the LNR502E(/M) Encoded Translation Stage combines a linear optical encoder and everything included with the LNR502(/M) stage to achieve a minimum repeatable incremental movement of 0.1 µm and improved bidirectional repeatability of ±0.75 µm.
Mounting Adapters and Stage Combinations
Thorlabs manufactures three adapter plates to maximize the mounting flexibility of these stages. The LNR50P2(/M) Right-Angle Bracket and LNR50P3(/M) Spacer Plate allow for easy configuration of left- or right-handed XY, XZ, or XYZ systems. A base plate, which provides sufficient clearance between the stage and the work surface for operation of the DRV250 stepper motor actuator, is included with each translation stage.
Included Actuator
The translation stages sold here include a DRV250 stepper motor actuator. For applications requiring fine positioning, the removable static pin that provides a stop for the stage's motor drive can be replaced by a piezo drive. Combining the standard stepper motor actuator with a piezo drive allows for both long travel and fine adjustment. Both open-loop and closed-loop piezo drives are available with 20 µm to 100 µm of travel and resolution as low as 5 nm.
Controller Options
For stepper motors such as the one included with the LNR502(/M) and LNR502E(/M) translation stages, Thorlabs recommends using a BSC201, BSC202, or BSC203 Stepper Motor Controller. Any of these controllers can be purchased separately.
Thorlabs also manufactures the MTS50-Z8 Motorized Translation Stage, which features a built-in actuator and reduced overall package size.

Thorlabs offers two platforms to drive our wide range of motion controllers: our Kinesis® software package or the legacy APT™ (Advanced Positioning Technology) software package. Either package can be used to control devices in the Kinesis 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 .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.
Kinesis GUI Screen
APT GUI Screen
Our legacy APT System Software platform offers ActiveX-based controls which can be used by 3rd party developers working on C#, Visual Basic, LabVIEW™, or any Active-X compatible languages to create custom applications and includes a simulator mode to assist in developing custom applications without requiring hardware.
By providing these common software platforms, Thorlabs has ensured that users can easily mix and match any of the Kinesis and 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 single-axis to 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.
A range of video tutorials is 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.

(posted 2021-01-21 00:17:33.41) Can APT user (APT driver) program or Micro-manager be installed with window 2000 OS?
I'd like to use the LNR502 with win 2000 OS, because of the old school microscope operating application. cwright
(posted 2021-01-21 10:12:21.0) Response from Charles at Thorlabs: Thank you for your query. Unfortunately APT was not designed for Windows 2000 OS. I can see from Micromanager's website that they also do not support Windows 2000. You should still be able to communicate with these stages using serial commands listed in the APT communications protocol: https://www.thorlabs.com/Software/Motion%20Control/APT_Communications_Protocol.pdf wenzel.jakob
(posted 2017-12-08 12:56:50.187) Can rigid stands (e.g. MP100) be mounted on top of the TravelMax translation stages? bwood
(posted 2017-12-13 11:15:42.0) Response from Ben at Thorlabs: Thank you for your feedback. The counterbored slots (appropriate for both 2" and 50mm hole spacing) of the MP100 match with four of the holes on the LNR50. Therefore I am pleased to say you can mount a rigid stand on an LNR50. rayotte
(posted 2017-08-25 11:11:50.04) We have been using the LNR50S for several years. It is beginning to squeal now. Is there a recommended or suggested lubrication and application method available? Thanks. bwood
(posted 2017-09-05 10:27:26.0) Response from Ben at Thorlabs: Thank you for your feedback. There are some ways to lubricate the LNR and attached motor. I will be in direct contact with you to identify the cause of the noise, and the appropriate responce. Sdm314
(posted 2017-01-19 11:09:31.643) Is there a minumum velocity for these stages? We are looking for a stage that can reliably move at speeds of 5-100 um/s. bwood
(posted 2017-01-20 04:10:49.0) Response from Ben at Thorlabs: The theoretical minimum velocity is that which can be commanded by our motion control software, that velocity range is achievable. However, at low velocities the motion of any 2 -phase stepper motor will become unstable. As you reduce the velocity of the stage, the movement may seem to microscopically ‘stop-start’ depending on the application’s requirements. This is due to the time between motor phases increasing to produce this ultra-low velocity which consequently leads to the motor stalling if there are torque hotspots, where say the pitch of the leadscrew is not perfect. This will vary between each model as at this slow speed any irregularities in the stage are emphasised. This would also be heavily dependent upon the load employed. ludoangot
(posted 2016-11-17 09:29:32.267) Ben, thank you. You propose the DDSM50 which I had also considered but from its characteristics (direct drive with no inertia) I understood it is not suitable for z-axis translation (I specified a 600g load on the z-axis). I may be mistaken. How to set up / control the DDSM50 for z-axis translation? bwood
(posted 2016-11-17 04:23:23.0) Response from Ben at Thorlabs: Yes, you are correct, direct drive stages are not recommended for z-axis translation. Apologies if my comment caused any confusion. The LNR50S is probably the best option for the specifications you gave, however if you would like to further discuss your requirements it may be more convient if you email me at techsupport.uk@thorlabs.com ludoangot
(posted 2016-11-10 17:20:30.033) The LNR50S fits my requirements in terms of velocity, what absolute position accuracy can I expect from this non-encoded version and why isn't this accuracy not specified (it may be because it can't be guaranteed?)? Also, I don't need 50mm travel, 12~20mm is ample, but your other travelMax (LNR25ZFS) has a velocity of only 2mm/s. In the hope of finding a less expensive solution, do you offer a 12~20mm travel motorized stage with at least a 10mm/s velocity and better than 5um position accuracy (load would be about 600g, in the z-axis)? bwood
(posted 2016-11-11 05:58:22.0) Response from Ben at Thorlabs:Thank you for your question. We specify the absolute on-axis accuracy for the LNR50S as 10µm. From the specifications you have given, I think another option you may want to consider is the DDSM50. This stage offers up to 500 mm/s velocities, ±5µm accuracy and has a 0.9kg load capacity. It can be found on our website here: https://www.thorlabs.hk/newgrouppage9.cfm?objectgroup_id=8535 christopher.jones
(posted 2016-05-06 15:51:36.013) Hello. I am interested in the LNR50 series, esp. LNR50SE/M. Do you stock an adapter plate (or combination) to mount these stages onto your X95 rail system? We use the X95 rail system as a gantry and need to support a sensor with z motion off the gantry crossbar. bwood
(posted 2016-05-09 11:32:28.0) Response from Ben at Thorlabs: Thank you for your question. We have many possible mounting solutions available in this circumstance, and we will be in contact with you directly to discuss your options here. 2yongmoon
(posted 2016-04-02 02:38:51.073) I'm using LNR50S/M with TST101 controller. Since the available power of TST101 is lower than theat of BSC series, sometimes it cause problem at the end of stage(at the maximumly stretched position of spring). But, the steeper actuator(DRV014) make the scarpe of iron at the position, also. So I think it can be solved by smoothing them. So, can I use grease at the part of the contact, or is there some solutions for this problem? msoulby
(posted 2016-04-07 04:15:25.0) Response from Mike at Thorlabs: The DRV014 is a larger motor it requires more power to drive the motor therefore the recommended driver for the DRV014 is the BSC20x benchtop stepper controller. If you use the TST101 with the DRV014 then due to the lower output the controller may not be able to supply enough current to drive the stage correctly especially if the stage is loaded. The sound you are hearing is likely the motor stalling due to the TST101 not being able to supply enough current to drive the motor against the load. As there is less torque available then one possible solution would be to significantly reduce the velocity at which you drive the DRV014 with the TST101. hhj5443
(posted 2014-07-21 12:26:54.54) Hello. I have a question.
I want to do a cyclic test with PDMS.
As you know, this linear translation stage's maximum load is 30kg (nearly 300MPa)
But 2.3~2.5MPa is enough to stretch the PDMS so I think 300MPa seems to be too large for testing PDMS.
So I want to know the minimum load that is sensible. bhallewell
(posted 2014-07-25 05:57:20.0) Response from Ben at Thorlabs: Thank you for your question. The LNR50S range holds no minimum load spec. The stage will function to specification between zero load & the orientation-dependent max load specs outlined. jjurado
(posted 2011-07-12 16:15:00.0) Response from Javier at Thorlabs to ax4solid: Thank you for contacting us. You can certainly use LabVIEW to control the LNR50SE/M stage. Our APT software is built on the ActiveX platform, so it can be imported into LabVIEW without the need for drivers. The installation package also contains tutorial videos, a help file with method descriptions, and basic, intermediate, and advanced sample vi's. We also offer a guide for programming the APT software in LabVIEW, which you can find in the BSC101 controller page: http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=1704 (click on the APT Tutorials Tab)
I will contact you directly for further support. ax4solid
(posted 2011-07-12 10:44:44.0) Good day,
I would like to inquire about the mentioned device and the controller. I would like to know if Labview could be used to run the controller and if so, would the SDK be provided for use when purchased.
Thank you.
cheers.

Motorized Linear Translation Stages
Thorlabs' motorized linear translation stages are offered in a range of maximum travel distances, from a stage with 20 µm of piezo translation to our 600 mm direct drive stage. Many of these stages can be assembled in multi-axis configurations, providing XY or XYZ translation. For fiber coupling applications, please see our multi-axis stages, which offer finer adjustment than our standard motorized translation stages. In addition to motorized linear translation stages, we offer motorized rotation stages, pitch and yaw platforms, and goniometers. We also offer manual translation stages.
Piezo Stages
These stages incorporate piezoelectric elements in a variety of drive mechanisms. Our Nanoflex™ translation stages use standard piezo chips along with manual actuators. Our LPS710E z-axis stage features a mechanically amplified piezo design and includes a matched controller. The PD1 stage incorporates a piezo inertia drive that uses "stick-slip" friction properties to obtain an extended travel range. The Elliptec™ stages use resonant piezo motors to push and pull the moving platform through resonant elliptical motion.

Direct Drive Stages
These low-profile stages feature integrated brushless DC servo motors for high speed translation with zero backlash. When no power is applied, the platforms of these stages have very little inertia and are virtually free running. Hence these stages may not be suitable for applications where the stage's platform needs to remain in a set position when the power is off. We do not recommend mounting these stages vertically.

- Minimum Repeatable Incremental Movement of 1 µm when used with a Stepper
Motor Controller - Thirteen 1/4"-20 (M6) Tapped Holes on the Top Surface
- Six Dowel Alignment Pins Included for Use with Mounting Accessories
- Controller Sold Separately
Thorlabs' LNR502(/M) TravelMax Motorized Translation Stage is designed for long travel and horizontal load capacities up to 48 kg (105 lbs). The stage is made from thermally matched steel for high stability even in less-than-ideal conditions. For compatibility with a wide variety of optomechanical setups, the stage incorporates a 3.94" x 3.94" (100.0 mm x 100.0 mm) moving platform with thirteen 1/4"-20 (M6) tapped holes and can be stacked with additional LNR502 stages in XY, XZ, and XYZ configurations using the adapters sold below.
This motorized translation stage incorporates a DRV250 Stepper Motor Drive. A controller must be purchased separately; we recommend pairing with our BSC201, BSC202, or BSC203 Stepper Motor Controllers to obtain optimal performance and a minimum achievable incremental movement of 0.05 µm.
The motor cable that is built into the DRV250 stepper motor actuator is 0.5 mm (1.64 ft) long. A 3 m (9.8 ft) PAA613 cable is included with this stage for use with our benchtop controllers. Replacement cables are available at the bottom of the page.

- Thirteen 1/4"-20 (M6) Tapped Holes on the Top Surface
- Six Dowel Alignment Pins Included for Use with Mounting Accessories
- Controller Sold Separately
The LNR502E(/M) TravelMax Motorized Translation Stage combines the LNR502(/M) motorized translation stage (sold above) with an integrated linear optical encoder to reduce the minimum repeatable incremental movement from 1 µm to 0.1 µm and the bidirectional repeatability from ±3.9 µm to ±0.75 µm. This stage is designed for applications where stability, long travel, and high horizontal load capacity [48 kg (105 lbs)] need to be coupled with absolute position accuracy.
As with the LNR502 stage above, the encoded version has a 3.94" x 3.94" (100.0 mm x 100.0 mm) moving platform with thirteen 1/4"-20 (M6) tapped holes and can be stacked with additional LNR502 stages in XY, XZ, and XYZ configurations using the adapters sold below.
Dedicated software that takes full advantage of the high-resolution linear optical encoder is included. This software, when combined with one of Thorlabs' BSC201, BSC202, or BSC203 closed-loop stepper motor controllers, can provide an application solution that is fully operational out of the box.
This translation stage's linear optical encoder is directly attached to the stage's moving platform to provide the necessary feedback to the drive electronics. Since the encoder provides a direct readout of the absolute position, the mechanical positioning errors associated with backlash can be ignored.
The motor cable that is built into the DRV250 stepper motor actuator is 0.5 m (1.64 ft) long. A 3 m (9.8 ft) PAA613 cable is included with this stage for use with our benchtop controllers. Replacement cables are available at the bottom of the page.

- Dimensions (L x W x H): 3.94" x 3.94" x 0.94" (100 mm x 100 mm x 24 mm)
The LNR50P3(/M) XY Mounting Adapter provides the necessary clearance between separate LNR502(/M) and LNR502E(/M) translation stages for a left- or right-handed XY translation stage configuration. On the adapter, there are six 1/4"-20 (M6) tapped holes, four dowel pin holes, one counterbore for 1/4"-20 (M6) cap screws, and two Ø0.29" (7.5 mm) through holes. An example of an XY arrangement is shown to the right. This was assembled using the LNR50P3 Mounting Adapter, LNR50P4 Base Plate, and two LNR50 Series Translation Stages. By incorporating a third translation stage and an LNR50P2(/M) Right-Angle Bracket (sold below), a left- or right-handed XYZ translation stage can also be constructed. Dowel pins are included for easy alignment of the stage.

- Dimensions (L x W x H): 4.25" x 3.46" x 5.26" (108 mm x 88 mm x 134 mm)
The LNR50P2(/M) is an anodized aluminum right-angle bracket that orients the LNR502(/M) and LNR502E(/M) translation stages in a vertical orientation. This allows for the construction of XZ and XYZ translation stage configurations.
The base of the LNR50P2 contains six counterbored holes for 1/4"-20 (M6) cap screws, allowing it to be attached to the top of an LNR50 series stage or directly to an optical table. The vertical side has two 1/4"-20 (M6) tapped holes and eight Ø0.28" (7.0 mm) through holes.
The XYZ assembly shown to the right was constructed using the LNR50P2 Right-Angle Bracket, LNR50P3 Adapter Plate, LNR50P4 Base Plate, and three LNR502 translation stages. The LNR50P4 and LNR50P3 Mounting Adapters are sold above. Dowel pins are included with the base plate, adapter plate, and right-angle bracket to assist in alignment of the stage.
