Thorlabs' LTS300(/M) Linear Translation Stage with Integrated Controller is optimized for applications requiring high load capacity and high resolution, such as measurement and inspection. It provides 300 mm of linear travel for loads as great as 15 kg (33.1 lbs) when mounted horizontally and 4 kg (8.8 lbs) when mounted vertically. Each stage features an on-axis accuracy of 5.0 µm (Min) when the unit-specific calibration files are used with the Thorlabs Kinesis or APT™ software. 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 LTS300(/M) stage features an integrated electronic controller that can be controlled remotely using a PC or manually via the buttons and velocity potentiometer on the control keypad (see photo to the left). Parameter settings can be adjusted on the PC and stored in non-volatile memory within the unit itself. When the unit is powered up, these settings are applied automatically. This is particularly useful when the stage is being used manually in the absence of a PC and USB link.

The stage is lightweight, compact, and robust with high performance over the full travel range. The heavy-duty aluminum construction and 40 mm moving platform height makes this stage ideal for applications where space is limited. Integrated magnetic limit switches allow homing and overdrive protection in both directions. A precision-ground lead screw delivers smooth, virtually noise-free movement. The power supply provided with the stage operates with 90 - 264 VAC input voltages (47 - 63 Hz) and is shipped with a location-specific power cord.

Thorlabs also offers the LTS150(/M) Linear Translation Stage with Integrated Controller, which features 150 mm of travel.

Calibration Files
Each LTS300(/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 Kinesis or APT software and included calibration files. These files are used by the 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 them, the repeatability and resolution of the stage are unaffected, but no compensations are made to enhance the accuracy. Each stage is calibrated at the factory, giving a typical on-axis accuracy of 47 µm without the use of the calibration files.

Stage Combinations
If an XY configuration is desired, any combination of LTS300(/M) and LTS150(/M) Linear Positioning Stages (the latter features a 150 mm travel range) can be mounted atop one another using the LTSP1(/M) XY Adapter Plate (sold below). XZ and XYZ configurations are possible using our LTSP3(/M) Z-Axis Bracket, which orients an LTS300(/M) stage in the vertical plane. Please note that stages and adapters with imperial or metric taps are only compatible with other stages and adapters featuring the same thread standards.

The ActiveX® APT system software is also compatible with other APT family controllers, including our multi-channel controllers, rack-based controller, and smaller, optical-table-mountable K-Cube™ controllers. This single unified software offering allows seamless mixing of the LTS300(/M) stages with any APT benchtop, tabletop, or rack-based controllers.

  • Max Velocity, Max Acceleration, and Max Load
    The max velocity and acceleration values quoted above are achievable with lighter loads. As the load is increased, the velocity and acceleration should be decreased accordingly. For the maximum 15 kg load, the velocity should be reduced to either 15 mm/s with 3 mm/s2 acceleration or 12 mm/sec with 5 mm/s2 acceleration, depending upon whether speed or acceleration is more important for the intended application.
  • Min Achievable Incremental Movement
    The measured minimum incremental motion that the stage can achieve, also referred to as the minimum step size.
  • Min Repeatable Incremental Movement
    The minimum incremental motion that the stage can repeatedly achieve within its standard error.
  • On-Axis Accuracy
    This is the absolute accuracy of the commanded position. It is defined as the maximum discrepancy between the commanded position and the absolute position over the full travel of the stage. For example, if a stage is specified with an on-axis accuracy of 20 µm, then a command to travel to 10 mm will result in an absolute position of within 20 µm of 10 mm. 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 (see Note C for details) as the discrepancy between commanded position and absolute position generally increases linearly with the amount of travel. This gives rise to an on-axis accuracy near the end of the travel range of the stage which is generally lower than the accuracy at the beginning of the travel range. A percentage accuracy can give you a good idea of what to typically expect along the stage's travel. Accuracy should not be confused with repeatability, which refers to the ability of the stage to travel to the commanded position over many attempts.
  • On-Axis Maximum Percentage Accuracy
    This is the maximum discrepancy between the commanded position and the absolute position expressed as (|Pabsolute - Pcommanded| / Pcommanded) and gives a better idea of what to typically expect along a stage's travel. The advantage of expressing this as a percentage is that the higher accuracy at the lower travel range of a stage can now be represented. As the maximum percentage error will not necessarily be at full travel, this means the value given will be an excellent representation of the maximum possible error that can be expected.
  • Pitch and Yaw
    Pitch and Yaw define how much the moving world shifts as the stage translates. Pitch is measured by moving the stage over its full travel range and taking an angular robust laser interferometry (RLI) measurement in the pitch axis at 20 equidistant points along the travel. This is repeated 10 times and the maximum discrepancy between minimum and maximum value taken. Yaw is measured using the same procedure.

Controller Features

The LTS300(/M) stage features an integrated APT™ compatible controller that can operated using either the manual keypad or remote computer control using APT software. The controller is fully configurable with key parameters exposed through the associated software graphical interface panels. Jog step sizes can be selected, phase currents can be limited to suitable peak powers as required, and limit switch configuration is accommodated through flexible logic settings.

In addition, relative and absolute moves can be initiated with move profiles set using velocity profile parameters (including acceleration/deceleration). Similarly, homing sequences have a full set of associated parameters that can be adjusted for a particular application. For ease of use, the APT software incorporates pre-configured settings for the LTS300(/M) stage.


All key parameters may be adjusted using our intuitive software graphical panels. For example, a move to the next position can be initiated by clicking directly on the position display and entering a new value. These settings and parameters are also accessible through the ActiveX® programmable interfaces for automated alignment sequences. Refer to the Motion Control Software tab for further information on the APT software support for the BSC200 Series.

Full Software GUI Control Suite & ActiveX Controls Included

A full and sophisticated software support suite for use with the LTS300(/M) stage includes a number of user utilities that allow immediate operation of the unit without any detailed pre-configuration. All operating modes can be accessed manually, and all operating parameters may be changed and saved for future use. For more advanced motion control applications, a fully featured ActiveX programming environment is also available to facilitate custom application development in a wide range of programming environments. Note that all settings and parameters described above are also accessible through these ActiveX programmable interfaces. For further information on the APT software support for the LTS300(/M) stage, refer to the Motion Control Software tab. Demonstration videos illustrating how to program the APT software are also available on the APT Tutorials tab.

MMR600 Family of Rack Mounted Controllers

The ActiveX APT system software is also compatible with other APT family controllers, including our multi-channel benchtop units, rack-based systems, and smaller optical table mountable T-Cube™ controllers. This allows for allows seamless mixing of components. The common software architecture also makes it easy to create automated alignment/positioning systems which interact at the software level. All controllers in the APT range are equipped with USB connectivity. This allows multiple APT units to be connected to a single controller PC using USB hubs and cables. When planning a multi-channel application, simply add up the number and type of drive channels required and connect together the associated number of APT controllers.

Software Development Support

A development kit is included in the APT software for developers working on large, system integration projects that incorporate APT products. The kit contains an extensive selection of code samples as well as a library of video tutorials. Please see the Motion Control Software tab for details.

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.

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.

The APT video tutorials available here fall into two main groups - one group covers using the supplied APT utilities and the second group covers programming the APT System using a selection of different programming environments.

Disclaimer: The videos below were originally produced in Adobe Flash. Following the discontinuation of Flash after 2020, these tutorials were re-recorded for future use. The Flash Player controls still appear in the bottom of each video, but they are not functional.

Every APT controller is supplied with the utilities APTUser and APTConfig. APTUser provides a quick and easy way of interacting with the APT control hardware using intuitive graphical control panels. APTConfig is an 'off-line' utility that allows various system wide settings to be made such as pre-selecting mechanical stage types and associating them with specific motion controllers.

APT User Utility

The first video below gives an overview of using the APTUser Utility. The OptoDriver single channel controller products can be operated via their front panel controls in the absence of a control PC. The stored settings relating to the operation of these front panel controls can be changed using the APTUser utility. The second video illustrates this process.

APT Config Utility

There are various APT system-wide settings that can be made using the APT Config utility, including setting up a simulated hardware configuration and associating mechanical stages with specific motor drive channels. The first video presents a brief overview of the APT Config application. More details on creating a simulated hardware configuration and making stage associations are present in the next two videos.

APT Programming

The APT Software System is implemented as a collection of ActiveX Controls. ActiveX Controls are language-independant software modules that provide both a graphical user interface and a programming interface. There is an ActiveX Control type for each type of hardware unit, e.g. a Motor ActiveX Control covers operation with any type of APT motor controller (DC or stepper). Many Windows software development environments and languages directly support ActiveX Controls, and, once such a Control is embedded into a custom application, all of the functionality it contains is immediately available to the application for automated operation. The videos below illustrate the basics of using the APT ActiveX Controls with LabVIEW, Visual Basic, and Visual C++. Note that many other languages support ActiveX including LabWindows CVI, C++ Builder, VB.NET, C#.NET, Office VBA, Matlab, HPVEE etc. Although these environments are not covered specifically by the tutorial videos, many of the ideas shown will still be relevant to using these other languages.

Visual Basic

Part 1 illustrates how to get an APT ActiveX Control running within Visual Basic, and Part 2 goes on to show how to program a custom positioning sequence.

Full Active support is provided by LabVIEW and the series of tutorial videos below illustrate the basic building blocks in creating a custom APT motion control sequence. We start by showing how to call up the Thorlabs-supplied online help during software development. Part 2 illustrates how to create an APT ActiveX Control. ActiveX Controls provide both Methods (i.e. Functions) and Properties (i.e. Value Settings). Parts 3 and 4 show how to create and wire up both the methods and properties exposed by an ActiveX Control. Finally, in Part 5, we pull everything together and show a completed LabVIEW example program that demonstrates a custom move sequence.

Response from Jack at Thorlabs: Thank you for your inquiry. The first warning is displayed as Matlab are removing support for ActiveX controls in future releases. The error 'Control creation failed. Invalid ProgID 'MGMOTOR.MGMotorCtrl.1' most typically occurs because the ActiveX control is not present and registered on the target machine. However I will reach out to you to help troubleshoot further.

I would like to understand the mechanical safety risk for this item (LTS300). What would happen if a finger is trapped in between the moving stage. How severely would the injury be?
DJayasuriya  (posted 2020-11-17 04:20:06.0)
Thank you for your inquiry. The LTS leadscrew is directly connected to the motor making it relatively easier to stall. However different velocities would have different forces to stall. A peak force meter would give prices measurement of force to stall. Depending on how fast the moving world is traveling we would say it could injure a finger. We will get in touch with you directly with these measurements

Hi, I am still struggling with LTS devices. I still cannot use them via C API. I am just wondering if you had a full example code how to e.g. initialize and move the stage back and forth? The example codes in your C API help seem to be a bit old and they are just parts of some bigger full code. I can open and use the API commands but the stages do not fully work. I think the problem would be in the initialization and my question regarding that is Should I initialize stages by using Kinesis software or do I have to do it completely in my C++ software? The API commands are not clearly documented. E.g LoadSettings, should I use it. Does this load something initialized with Kinesis software? Perttu

Hi, Still one question more.. As I did not manage to add controls onto visual studio c++ console application.. Bit unsatisfied that also ActiveX component did not locate in the list of ActiveX components in Visual Studio MFC application. That is stupid that there is mensioned how easy the device is to integrate. There are good video tutorials and much text but they do not work for me. In earlier message I mensioned that I have installed APT and Kinesis software for 64-bit windows and through them I do can easily control my LTS150 and LTS300 devices.. Perhaps if I fight a couple of days I may understand why but now I am a bit unsatisfied.

Dear Sir/Madame, I am writing to you due to technical issue with the LTS300 motorized stage. I have bought one of the LTS300 stages and have found some problems with programming the stage using the APT software. I am writing my software using the C# .NET and it is really uncomfortable to me to use the COM based ActiveX controls. I have found on your webpage that it is possible to use classic .dll library to communicate with the stage. However such information is on the website I couldn’t find the file after installing the APT package. Is it possible to get the standard .DLL file for the LTS300? It is more beneficial to me to write a .NET wrapper than use the ActiveX controls. I am looking to hear from you. Sincerely yours Bartłomiej Cichy

how do I enable different channels for different stages? We have two LTS300/M, we'd like to have them move simultaneously. thanks,

Response from Rob at Thorlabs: Thank you for your feedback. To control multiple channels at once, the use of third party software will be needed. Examples of such software include LabVIEW and MATLAB. I will contact you by email to further clarify this.

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.

Three LTS300 Stages Mounted in XYZ Configuration Using LTSP3 Bracket and LTSP1 Plate
  • Mount an LTS300(/M) Stage in XZ and XYZ Configurations
  • Stage can be Mounted in Left- or Right-Handed Setups
  • Not Designed for Direct Breadboard Mounting (See Below)

The LTSP3(/M) right angle bracket allows an LTS300(/M) stage to be mounted in a vertical (Z-axis) orientation as shown to the right. XYZ configurations can be made using an LTSP1(/M) adapter plate (sold above) and LTSP3(/M) angle bracket.

Please note that these adapters are not designed for mounting directly to a breadboard. The bottom of the vertical stage extends past the base of the adapter, and thus, the adapter must be elevated above the table to provide adequate clearance for the stage.
