Thorlabs' MTS50-Z8 (MTS50/M-Z8) Motorized Translation Stage features 50 mm (1.97") of electronically controlled linear travel along a well-defined axis. Each stage is equipped with a 1.50" x 1.50" (37.5 mm x 37.5 mm) tapped hole matrix that includes eighteen 4-40 (M3) taps and a centered 8-32 (M4) tap. By integrating the moving platform with the actuator, the overall package size is greatly reduced relative to other motorized stages like the LNR502(/M) Motorized Stage.

The moving platform contains holes for alignment pins that ensure orthogonality when the stage is stacked with other stages or connected to our accessories. Horizontal loads of 25 lbs (12 kg) and vertical loads of 10 lbs (4.5 kg) are supported by the 67:1 planetary gear head. A built-in Hall Effect encoder provides 29 nm resolution (see the Specs tab for additional details).

The translation mechanism, based upon a dual set of linear rails with continuously recirculating ball bearings, provides smooth, low-friction movement. Built-in limit switches prevent travel outside of the intended range, regardless of the control interface being used.

Mounting Adapters and Stage Combinations
Thorlabs' adapter plates and brackets provide a convenient way to mount the MTS50-Z8 on an optical table or breadboard; to install a motor along the optical axis of our 60 mm cage systems; and to allow several stages to be combined in XY, XZ, or XYZ configurations. A multi-hole adapter plate is also available that offers seven 1/4"-20 (M6) and six 8-32 (M4) tapped holes, providing more options when mounting standard optical accessories to the top platform. Our MTS25-Z8 25 mm (0.98") Motorized Translation Stage can also be combined with the MTS50-Z8 in certain arrangements. All these uses are described in greater detail below.

Controller Options
The KDC101 DC Servo Motor Controller is required to operate the stage and is sold separately below. Alternatively, we offer the KMTS50E bundle, which includes the MTS50-Z8 translation stage, the KDC101 DC Servo Controller, and a power supply at a significant savings over ordering these items separately.

The KDC101 provides control for a single axis, with or without a PC. It is bundled with Thorlabs' Kinesis^® software, which supplies out-of-the-box stage control from a PC and enables support for common programming interfaces like LabVIEW and LabWindows. A USB cable is included with the KDC101.

Thorlabs also manufactures the LNR502(/M) Motorized Stage, which features a larger mounting surface for even more flexibility.

Resolution Calculation

For the MTS50-Z8 (MTS50/M-Z8), there are 512 encoder counts per revolution of the motor. The output shaft of the motor goes into a 67:1 planetary gear head. This requires the motor to rotate 67 times to rotate the 1.0 mm pitch lead screw one revolution. The end result is the lead screw advances by 1.0 mm.

The linear displacement of the actuator per encoder count is given by

512 x 67 = 34,304 encoder counts per revolution of the lead screw,

whereas the linear displacement of the lead screw per encoder count is given by

1.0 mm / 34,304 counts = 2.9 x 10^-5 mm (29 nm).

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.

Dear Thorlabs, Can you control the MTS50/M-Z8 stage with micro-manager? Best regards, Christian Maibohm

cwright (posted 2020-08-10 08:56:13.0)

Response from Charles at Thorlabs: Hello Christian and thank you for contacting us. Unfortunately the ThorLabs modules created for our APT-Compatible stages were not developed by us and we do not know how these are set up. Based on the list of Device Support on Micromanager's website, it does not appear that the KDC101 controller, which would be required to control this stage, has been implemented.

Hello, there is statement in details that Absolute On-Axis Accuracy is 290 µm. Is that correct? seems quite large value compared to other specs

DJayasuriya (posted 2020-02-11 05:38:04.0)

Response from Thorlabs: Hello, thank you for your enquiry. This is due to the lead screw of the unit having some imperfections and the configuration of the gear box ratio that causes the on axis accuracy spec. Hope this helps clarify your question.

Ahsanul Torza (posted 2019-12-19 12:56:40.1)

I am running this stage in a 3-axis configuration using the MG17 motors. When I run my labview code in any direction the motor allows the stage to move smoothly In one direction but when it starts moving towards the other direction it jerks which causes a problem in all of my data collecting. This happens in all the axis, thanks and hope to hear back soon

user (posted 2019-12-20 08:28:00.0)

Response from Charles at Thorlabs: Hello Ahsanul, thank you for letting us know you are having trouble. It sounds like this could be the result of a sharp change in acceleration and may be solved by altering the velocity profile. Since troubleshooting could require seeing your VI, and a bit of back and forth, a member of our technical support team will reach out to you directly to assist with this.

Lindsey Barner (posted 2019-08-08 03:25:51.06)

Hi, I purchased an MMTS50-Z8 stage and its respective controller a few months ago, and I was wondering if I could return the item because it is faulty. When translating, it experiences a very obvious wobble that is out of spec. Let me know, thanks so much! Lindsey Barner

rmiron (posted 2019-08-08 06:02:08.0)

Response from Radu at Thorlabs: Hello Lindsey. Because the lead screw is unsupported at one end and because of imperfections in the manufacturing process, the lead screw of MTS50-Z8 wobbles. This wobbling is usually visible with the naked eye, but does not affect the performance of the stage. We still test whether the stage meets the specs listed on the website before stocking it. While we do not post a spec for the max wobbliness of the lead screw, we do post straightness and on-axis accuracy specs that in theory could be affected by an unusually wobbly lead screw. If you find that the stage changes its position by more than 50 um in a direction perpendicular to the travel direction, you are entitled to a replacement. The same holds true if the accuracy specs are not met (absolute & percentage accuracy). If that is the case, please contact your local technical support office, provide them the specs you have measured and a description of how they were measured and ask for a replacement. Alternatively, we could take the stage back for a free of charge evaluation.

hello, i have three mts50-z8 stages, but APT user program and also kinesis recognize one properly but two others as "Z606(B)" and gives them wrong speeds etc. How to program stages to have factory defaults ?

AManickavasagam (posted 2018-09-20 09:52:50.0)

Response from Arunthathi @ Thorlabs:Thanks for your query. There might be a possibility that the stage was used with a different controller previously and the settings were persisted accordingly. Please could you unintall any older versions of Kinesis (to avoid communication errors) and install the newest version of Kinesis from the website and run the firmware update utility which you should find in this location C:\Program Files (x86)\Thorlabs\Kinesis\Firmware Update Utility. If your PC is able to detect the stages (seen in control panel->device manager) then the connection/hardware should probably be fine and this might possibly be a firmware issue, by doing the above the issue you have may be resolved. Please do contact us directly if your issues persist.

Hello, I am trying to use your Kinesis Labview guide to run the MTS50-Z8. When I select The Thorlabs.MotionControl.Controls.dll in the .NET control, a long list of compatible Kinesis controls is displayed. What control should I select corresponding to MTS50-Z8? I looked up the Thorlabs.MotionControl.DotNet_API help file, and the model MTS50-Z8 is not listed. Thanks

bhallewell (posted 2018-05-22 03:09:33.0)

Response from Ben at Thorlabs: Thank you for your question. Our programming APIs refer typically to the controller being used as opposed to the stage. In this case, MTS50-Z8 is driven by the KDC101 controller, or our legacy variant - TDC001. Within the .NET API, you will find the Contents lists these Controllers with descriptions of relevant Namespaces, Methods & Properties.

Thank you for your feedback. How do I go about getting the correct configuration set in APT config? This software does not recognize any motors that are connected to the computer most of the time, and I do all of my control through LabView. I am looking for any way to get the stage to move into the currently negative range. Thank you.

jlow (posted 2014-07-29 03:13:12.0)

Hello, I am using LabView to control this linear stage (MTS50-Z8, using MoveAbsolute). The stage will not accept negative values despite the range of the stage being from -16 to 26 (or thereabouts). Do you know how to make the stage move to a negative value using LabView commands? Thank you.

msoulby (posted 2014-05-19 04:28:07.0)

Response from Mike at Thorlabs: When using the MoveAbsolute command it will always use the absolute position of the stage, for the MTS50 this range is 0-50mm where 0mm is the home position. It is always a good idea to home the stage first to set this absolute reference datum for the stage. With the correct configuration set in APT config you should not need to enter any negative values.

Kyle.Epp (posted 2014-02-07 12:34:42.21)

What is the axial (vertical) load capacity when the stage is mounted vertically? Will it be the same as the axial (horizontal) load capacity when the stage is mounted horizontally or how much is it affected by gravity?

msoulby (posted 2014-02-10 03:56:22.0)

Response from Mike at Thorlabs: The horizontal load capacity for the MTS50/M stages is 12kg. For a vertically mounted stage the load capacity reduces to just 4.5kg.

benjamin.r.anderson (posted 2013-12-17 17:58:43.38)

for the LNR50S it has the minimum increment as 0.1um, but with the inclusion of the controller the increment becomes 1um. Why? and is there a controller that can get the 0.1um? or do you need to have the encoded version

msoulby (posted 2013-12-18 04:05:28.0)

Response from Mike at Thorlabs: The minimum achievable incremental movement possible with the LNR50S and encoded version LNR50SE is 0.05um. The minimum repeatable incremental movement is 1um for the non-encoded version of the stage LNR50S and 0.1um for the encoded version of the stage LNR50SE. All of these specifications can be found on the ‘Specs’ tab on the product webpage. We will contact you directly to discuss some potential solutions for your application.

benjamin.r.anderson (posted 2013-12-17 17:55:41.627)

With the included controller what is the minimum step size?

msoulby (posted 2013-12-18 03:50:55.0)

Response from Mike at Thorlabs: The minimum increment is specified as 0.1um however the minimum increment that can be reliably repeated with the TDC001 and MTS50/M-Z8 is 0.8um. To achieve a minimum increment of 0.1um you should consider the following options: 1) The LNR50SE/M + BSC201 controller, this encoded stage and controller combination will allow you to achieve a minimum repeatable increment of 0.1um and a bidirectional repeatability of 0.3um. 2) The DDS220/M + BBD201 controller, this direct drive linear stage utilises a linear optical encoder allowing a minimum increment of 0.1um and bidirectional repeatability of 0.25um, it also has the added benefit of having zero mechanical backlash as there are no mechanical parts, such as lead screws or gears in the stage.

Response from Javier at Thorlabs to florent.cosandier: Thank you very much for contacting us. It is possible that LabVIEW is looking to execute a command before the previous command has been fully executed. It may be recommendable to use the GetStatusBits_Bits method before the beginning of a new command in order to ensure that the translation stage is ready for its next move. You can find the description of this method in Start > Thorlabs > APT > Help > APT Server Help. I will contact you for further support.

A response from Oli at Thorlabs to Graham: The encoders are digital pulse outputs which work as a quadrature output. Yes, 5 VDC to pin 10 should be applied to Vcc. The limit switch pins are wired such that they are literally switches that close when actuated by the stage, the return is pin 1 (ground) for both.

apalmentieri (posted 2010-03-09 09:28:02.0)

A response from Adam at Thorlabs to apolinar: To make a displacement of 10um, you can use the APT software that comes with the TDC001 controller. Either entering the distance of .01mm or using the jog function on the software will complete this 10um motion. There will be an error of ~0.7% when making this movement so you will see an overall movement between 9.9um-10.1um.

apolinar (posted 2010-03-08 20:08:21.0)

How can I make a displacement of 10 micrometers with this device?

apalmentieri (posted 2010-03-02 17:44:52.0)

A response from Adam at Thorlabs to chienchunglee: The infromation on our website is currenlty incorrect and we will be correcting this immediately. The encoder resolution is 512 counts per revolution and the gear box ratio is 67:1. The pitch of the lead screw is 1.0. The encoder resolution of the lead screw is calculated by the following formula: Lead screw enc resolution = (encoder res)*(Gearbox) = 34304 The counts/mm is calculated by the next formula: Counts/mm = (Lead screw enc res)*(Lead screw pitch) = 34308 counts/mm If you need low level comms documents, we can supply these as well.

chienchunglee (posted 2010-03-02 01:01:58.0)

The spec of MTS50-Z8E says the encoder counts per revolution of the leadscrew is 12,288. I wonder how could I convert this intro encoder counts per physical dimension (ex:mm) because I need this number to control TDC001 through low level language programming.

ghegenbart (posted 2008-01-31 07:14:55.0)

Comment on the MTS stage manual, section 5.1 and 5.2 (specs): In both sections a hall effect encoder is mentioned. On the first glace this gives the impression that there are two different encoders, one for the motor itself and one for the stage. I would like to propose to omit the specs for motor drive voltage, feedback, encoder counts and gearhead ratio in section 5.1

acable (posted 2007-12-23 15:53:21.0)

There is a lot on this page, since the visual navigation system break out the 25mm from the 50mm travel stages i would suggest the same is done with this page. The extra room could then me used to better detail the complete system (stage plus drivers). It would also be nice to provide a better connection between the NanoBlock family and this family, while you offer the adapter on this page there is no photo of how this would be used and hence i would guess very few people would notice the possible connecting of these two families of stages. Also the MTS25XYZ-E seem to be missing.

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.

Includes One 8-32 (M4) and Eighteen 4-40 (M3) Tapped Holes
Bundles Available with KDC101 Controller and KPS101 Power Supply
Multi-Axis, Breadboard, and 60 mm Cage System Mounting Adapters Offered Below

Thorlabs' MTS50-Z8 (MTS50/M-Z8) Motorized Translation Stage provides linear motion in one dimension. One centered 8-32 (M4) tapped hole and eighteen 4-40 (M3) tapped holes allow small optomechanics to be directly mounted to the moving platform. Based upon a dual set of linear rails with continuously recirculating ball bearings, the translation mechanism provides smooth, low-friction movement.

The stage requires our KDC101 DC Servo Motor Controller and Power Supply (each sold separately), which are described in more detail below. For convenience, we also offer a stage, KDC101 DC Servo controller, and KPS101 power supply in a bundle at a significant savings over purchasing these items individually. The power supply you receive will be compatible with outlets in your region. Please contact Tech Support prior to ordering if you require a different plug.

The motor cable that is built into the stage is 0.5 m (1.64 ft) long. If more length is required for your application, we recommend our PAA632 Extension Cable, which provides an additional 2.5 m (8.20 ft). It is sold at the bottom of this page.
