The Fully Extended MLJ150(/M) Mounted onto a Nexus Optical Table by 1/4"-20 (M6) Cap Screws
Features
- Motorized High-Load Vertical Translation Stage with Local or Remote Control
- USB and RS232 Computer Connections
- Smooth, Stepper Motor Driven Linear Motion
- Full Kinesis® or APT™ Software Control Suite (See Motion Control Software Tab for Details)
- Large Mounting Platform with 1/4"-20 (M6) Taps
- Location-Specific Power Supply Included
The MLJ150(/M) Motorized Vertical Translation Stage offers up to 50 mm of smooth, stepper motor driven linear height adjustment. Its integrated electronic controller allows for local control or CPU control via our software. This stage provides a rugged, height-adjustable platform ideal for mounting optomechanical sub-assemblies requiring height adjustment. It incorporates a large 5.83" x 5.16" mounting platform that is capable of moving loads up to 20 kg at up to 3 mm/s. Guards are fitted to completely eliminate finger traps and other obstructions. These features make it ideal to use as a heavy-duty lab jack.
The integrated electronic contoller facilitates local control via the keypad buttons and velocity potentiometer, as seen in the drawing to the right, as well as above. Alternatively, the MLJ150(/M) can be controlled remotely via USB or RS232 connections (see the Pin Diagram tab for connector information) by utilizing our Kinesis® or APT™ software suites. Parameter settings can be adjusted on the PC and stored in non-volatile memory within the unit itself. When the unit is next powered up, these settings are applied automatically. This feature is particularly useful when operating the unit manually in the absence of a PC link. Furthermore, the magnetic limit switches can be configured using flexible logic settings.
The stage offers excellent rigidity and platform parallelism. The top plate has twenty-five 1/4"-20 (M6) tapped holes with 0.31" (8.0 mm) depth, while the bottom plate has clearance slots that can be used to mount the stage to an optical breadboard, as shown to the right. The unit is supplied with a location-specific power supply with an input of 100 to 240 VAC. Please connect the power supply unit (PSU) to the stage before connecting the PSU to a power outlet. A USB cable for connection to a PC is also included.
Calibration Files
Each MLJ150(/M) stage is calibrated at the factory. 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 Kinesis or APT software and included calibration files. These files are used by the Kinesis or 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 
)
Software Control
USB and RS232 connectivity provides simple PC-controlled operation with two available software platforms: our new Kinesis software package, or our legacy APT software package. 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. Our legacy APT software allows the user to quickly set up complex move sequences with advanced controls made possible via the ActiveX® programming environment. For example, all relevant operating parameters are set automatically by the software for Thorlabs stage and actuator products. For more details on both software packages, please see the Motion Control Software, Kinesis Tutorials, and APT Tutorials tabs for more details.
Click for DetailsThe 5.83" x 5.16" (148 mm x 131 mm) top platform of the MLJ150(/M) has twenty-five 1/4"-20 (M6) mounting taps. The control keypad for manual control can be seen here.

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.

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.

(posted 2020-04-22 23:02:27.23) Hello, I have a question regarding the gearbox ratio of the MLJ050/M labjack. The specifications on the catalogue page say the gearbox ratio is 3 to 1. Additionally, the default settings XML file for Kinesis specifies a gearbox ratio of 3 to 1. However, the Thorlabs APT Communication Protocol document says the gearing is 1 mm/turn (i.e. ratio of 1 to 1). Can you please advise which is correct? Thank you! DJayasuriya
(posted 2020-04-24 06:50:20.0) Response from Dinuka at Thorlabs: Thanks for your query. Yes the gear box ratio is 3:1, from the APT protocol document, 1mm/turn is not the gear ratio relates to the encoder. The trinamics encoder gives 409600 micro‐steps per revolution. i.e. a 1 mm move requires 1228800 microsteps = 409600 microsteps * 3. Hope this helps. Salman Naqvi
(posted 2019-10-24 20:34:32.427) Hi,
We have half a dozen of these labjacks in our lab which speaks of their utility for our task. Sadly, we have started to experience issues driving them to the desired position. Randomly during some motion, labjack would make a loud beep and instead of throwing any error, stop midway but report that it has reached the destination! This makes the stage extremely unreliable for repeatable measurements. I haven't been able to find a way to troubleshoot it. For reference, we have been sending commands 0x0480 and 0x0453 via serial port on Windows 8. Can you please reach back to me and help us fix the problem if a fix exists?
Thanks

(posted 2019-08-13 10:28:06.373) Does the stage need to be re-calibrated after extensive use? (0-40mm travel distance, 20 times/ day) AManickavasagam
(posted 2019-08-14 09:07:12.0) Response from Arunthathi at Thorlabs: Thanks for your query. This will also depend on how long you have used the stage for, the load on it and etc. Typically we do not have a calibration schedule for this stage. FYI you can download the calibration file from the website or alternatively please contact your local tech support office with the serial number of your stage and we will be able to provide the calibration file. user
(posted 2019-07-19 15:25:46.223) When I connected this product with Kineses,the PC can not get response from the labjack,and the diagnostic log of kineses showed "Device not reponding(Error Code-33)".I don't know why this happened.Can you please help me to find the problem and solution,thank you. AManickavasagam
(posted 2019-07-26 03:46:33.0) Response from Arunthathi at Thorlabs: Thanks for reaching out to us. ‘Error code 33’ (indicating a comms failure) usually appears when using old versions of Kinesis with new hardware (firmware). This is displayed as a Generic Error in .NET API help file. This usually resolves when using the latest software; updating the firmware, power cycling the device and also restarting your computer for the update to fully take effect. If you still have any issues please contact your local tech support office for further help. Yanhua Ma

(posted 2019-04-11 04:57:13.3) HI!
I'm also interested in the long term position stability of the MLJ150/M. In your response to nitzan_chamiel (2019-02-28) you mentioned that you are currently running some tests on this.
Are there any (preliminary) results yet? For my experiment I would need stability in the sub micrometer range over several days, with a load of about 6kg.
Is there any (e.g mechanical) creep you know of?
Thanks in advance! rmiron
(posted 2019-04-11 06:56:07.0) Response from Radu at Thorlabs: Hello, Hanna. The testing that we ran was not extensive enough to enable us to post a specification on the website. Furthermore, it was not run in an isothermal environment. With that being said, I expect that the stage will drift by more than 1 um over several days. I will contact you directly in order to share the results I shared with Nitzan. nitzan_chamiel
(posted 2019-02-28 00:00:31.263) Hello,
In my application I plan to use the MLJ150 for coarse z adjustment, and an additional LPS710E (piezo Z stage) on top of it for fine z adjustment.
What is the stability of the MLJ150 when not moving?
Also, would I get higher stability with power off?
Thanks you,
Nitzan rmiron
(posted 2019-02-28 05:01:24.0) Response from Radu at Thorlabs: Hello Nitzan. At the moment, we do not have sufficient test data in order to specify the stability of this stage. With that being said, we ran two stability tests for it last week. I will contact you directly in order to share this data with you. We think that it will be more stable if powered off, but this might depend on the load place on it and again, we do not have sufficient data to be certain that this is the case. lebouquj
(posted 2019-02-21 14:00:33.18) We would like to control this device via the RS232 with a socket from a C program. We could not find the format and list of accepted commands in the existing documentation. Do you have it ? Thanks. rmiron
(posted 2019-02-22 07:29:39.0) Response from Radu at Thorlabs: The documentation of our serial commands protocol can be found here: https://www.thorlabs.com/Software/Motion%20Control/APT_Communications_Protocol.pdf
All the public commands are listed in that document. The protocol uses uint8 (hexadecimal) bytes, an 115200/8-N-1 configuration and no terminating bytes. 3206302534
(posted 2018-12-19 18:48:33.95) I do want to konw how many μsteps is 50mm divided to? rmiron
(posted 2018-12-19 10:32:10.0) Response from Radu at Thorlabs: In MLJ150, 1 mm corresponds to 409600 μsteps. Therefore, 50 mm correspond to 20480000 μsteps. I will suggest internally that our serial communications protocol's documentation gets updated such that it mentions this conversion ratio. akuznetsov
(posted 2017-11-15 22:09:15.357) Is this another windows ONLY product or does RS-232 port mean that it can actually be used on a Mac with USB to RS-232 adapter? There are a lot of Thorlabs products >$1000 that only have a USB interface and Kinesis/APT software which means I can't use them on my bench which requires a Mac to control the device under test and as a result requires Mac controllable hardware. bwood
(posted 2017-11-17 05:02:24.0) Response from Ben at Thorlabs: Thanks you for your question. The MLJ150 can be controlled completely through the RS232 connector, so it should be suitable for your application. I would like to note that while APT/Kinesis requires Windows, all devices controlled with this software can also be controlled through serial communications, as per the protocol we offer in the software section. Furthermore, most controllers and devices have auxiliary I/O options, as an alternative to USB control. oavramio
(posted 2017-11-10 12:31:10.803) I am currently trying to develop an experimental set up for precise compression experiments. Thus, I am looking for a very precise vertical translation stage.Although I am very interesting in the motorised labjack MLJ050 devise I still need to know some more things:
Which is the actual minimum velocity that the devise can achieve.
A theoretical resolution of 0.8 nm and an accuracy of 30 micrometers is reported in the specs of the devise. What does this actually mean?
How precisely would I be able to control the motor in terms of 1) Velocity, 2)Position. Would I be able, for instance, to control the exact number of steps of the motor I need him to do? bwood
(posted 2017-11-14 06:15:47.0) Response from Ben at Thorlabs: The theoretical minimum velocity is that which can be commanded by our motion control software. 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. This means it is hard to define the lower limits of the velocity. The theoretical resolution is the distance traveled in one microstep, however for the reasons above, moving by a set number of microsteps is impossible. The <30 µm value is the achievable accuracy of the stage. lorenzo.alligo

(posted 2017-02-09 09:54:27.0) Response from Ben at Thorlabs: I would firstly recommend testing the device in the Kinesis application first, to ensure the stage is communicating with your PC correctly. When using the .NET framework please make sure you have copied over all Kinesis .dlls into your project & select the Lab Jack .NET control. We have some steps outlined within the following guide.
https://www.thorlabs.com/Software/Motion%20Control/KINESIS/Kinesis-Labview.pdf
I'd further recommend ensuring that you have the correct version of Kinesis installed which matches your OS & version of LabVIEW. jingfang.wan

(posted 2014-01-14 17:31:22.09) Hello,
i'm using Labview to control the Motor. Unfortunatly during homing or moving (which takes 5-6 seconds) my Labview software isn't responding.
Do you have any idea how to fix it? (Even in a simple software, labview isn't responding at all, not only the frontpanel e.g., it's the hole software including change between front and block diagram e.g.).
Second question about a "is busy" function: Is there a command i could use to check if the system is still moving or if it is finished? I only know about the callback option.
What is the "bwait" option at the command "MoveAbsolute"? I could not find out what this option changes.
best regards msoulby
(posted 2014-01-15 06:50:06.0) Response from Mike at Thorlabs: All of the move commands have a bWait Boolean property. When bWait is set to TRUE then the move method will return only after the move has completed, the program flow will be halted until the move has completed. If bWait is set to FALSE then the method will return as soon as the move has initiated, allowing the program flow to continue without waiting for the move to complete. In labview setting bWait to TRUE may cause the GUI or front panel to freeze up until the move has completed, which will explain the 5-6 second wait you are experiencing. It is more efficient programming practice to set bWait to 'False' and respond to the MoveComplete event. This event driven approach allows your application to service other tasks while the motors are moving and will prevent your front panel from freezing up during the move. An alternative to the MoveComplete event would be to poll the status of the motor, to do this you would need to use the motor method LLGetStatusBits, details of which can be found in the APT server help file under Programming Guide>> Motor Control>>Motor Control Methods t.nguyen14
(posted 2013-03-03 23:14:31.637) We bought a Thorlabs labjack L490MZ/M from you few years ago, and now we want to calibrate it. But I don't have a calibration file as it is requested by ATP config software for calibarion.
Could you please help to give us a calibration file ?
Here is serial number of our Labjack : 46821236
Thank you very much for your help.

I am sorry to hear about the problems you're experiencing when using the L490MZ. I have addressed your two questions below.
1. It could be that the limit switch has been damaged. We just tested one unit with all the different setting options and it stopped every time even when the switch was ignored. We would be happy to evaluate your stage to see if the switch is broken, but please first verify the default limit switch and homing settings first:
Homing:
Direction - Reverse
Limit Switch - Reverse HW
Zero Offset: 0.2
Velocity: 0.4
Hardware Limit Switches:
Reverse - Switch Makes
Forward - Switch Makes
2. If you are still able to discover your hardware in APT firmware, please try and reprogram it again. Open APT config and select the Server tab. In here you can try to increase the Enumeration dwell time (how long the APT server spends looking for and initialising devices). Default is 5000ms, try 10000ms and make sure only one usb device is connected.
We have contacted you directly to provide additional assistance and arrange for the return and evaluation of your lab jack, if needed. macross
(posted 2012-03-15 14:26:16.0) Use L490MZ occur two problem.
1.when homing, a stage moves n reverse direction but motor can't stop finally. Because it was not get the reverse limit switch signal. I need your help quickly.
2.after I use APT firmware to flash firmware, I can't see the GUI interface in APT user. bdada

Thank you for your feedback on our motorized lab jack. Due to the scissor action of the stage, you will see the worst 'twist' on the first move, so you will see the error no matter the step size or travel distance. We are currently redesigning this stage to improve the deck parallelism. johannes.strauss
(posted 2012-02-08 02:53:20.0) Deck parallelism (<250µm hole travel range) is pretty much for my application. I need that 2” of total travel range, but for measuring 0.5” is sufficient. So my question: is deck parallelism at 0.5” movement also <250µm or even less? My tolerance is <100µm, is that realizable with your system? bdada

Thank you for your feedback. The 1mm/sec velocity is what we specify to ensure positional accuracy. We have contacted you to discuss if other products may be more suitable. For instance, the combination of LTS150 - Integrated 150 mm Travel Stage with a LTSP2 - Z-Axis Bracket would provide 3mm/s vertical velocity with a maximum vertical load capacity of 4kg, with 150mm of travel.
Or the LNR50S - 2" TravelMax Stage with Trapezoidal Stepper and LNR50P2 bracket would provide a maximum velocity of 8mm/s and a maximum vertical load capacity of 10kg, but limited to only 2” of travel.
We have contacted you to provide further support. excelkim.kim
(posted 2011-11-11 06:24:57.0) I have serious problem.
max. 1mm/sec velocity is so slow.
It takes too much time to enter the target position.
Is there any method to increase the velocity.
At your specification, max. rpm is over 700.
I think you could give me the solution.
Thank you. bdada

The L490MZ is designed such that it will not drop when it is unplugged from the power supply. Please contact TechSupport@thorlabs.com if you have further questions. felipe.aguilarsan
(posted 2011-09-15 17:12:50.0) Hello, I want to know if this product have something like "self locking at rest" for unplugged use in a determined position, thank you. user
(posted 2011-09-14 18:39:47.0) Supose I put a position X, if I unplug or turn off this device it will keep the same position rigidly? Like a self locking or something like that. jjurado
(posted 2011-05-20 13:54:00.0) Response from Javier at Thorlabs to gerbenjoshua: Thank you very much for contacting us. We have not developed drivers and documentation for interfacing our motorized stages with the Linux platform. gerbenjoshua
(posted 2011-05-20 14:53:07.0) Are Linux drivers available? bdada
(posted 2011-03-09 16:04:00.0) Response from Buki:
Thank you for using our feedback tool. The L490MZ is anodized so it is not vacuum compatible. However, we have offered unanodized L490 lab jacks as custom products before. I will contact you directly to discuss your appliction and determine if an unanodized L490MZ is feasible. paulgard
(posted 2011-03-08 19:57:25.0) Is L490-MZ vacuum compatible? |
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.
