150 mm Linear Translation Stage with Integrated Controller, Stepper Motor
Two LTS150 Stages in
Thorlabs' LTS150(/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 150 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.

Integrated Controller with Manual and Remote PC Control
The LTS150(/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 LTS300(/M) Linear Translation Stage with Integrated Controller, which features 300 mm of travel.
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 20 µm without the use of the calibration files.
The LTS150(/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 LTS150(/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 LTS150(/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 LTS150(/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.
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.
USB Type B
2 m (6.5 ft) USB Type B to Type A Cable Included
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.
This guide illustrates some of the basics of using the APT System Software in LabVIEW from a programming point of view that allow immediate command of the APT controllers out of the box.
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.
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.
Stepper Motor Stages
These translation stages feature removable or integrated stepper motors and long travel ranges up to 300 mm. The MLJ150 stage also offers high load capacity vertical translation. The other stages can be assembled into multi-axis configurations.
DC Servo Motor Stages
Thorlabs offers linear translation stages with removable or integrated DC servo motors. These stages feature low profiles and can be assembled in multi-axis configurations.
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.
Thorlabs' LTS150(/M) stage provides 150 mm (5.9") of travel with an integrated stepper motor and controller. The controller features manual keypad and remote computer control. Optomechanics can be directly mounted to the moving platform using sixteen 1/4"-20 (M6) tapped holes, which are spaced 1.0" (25.0 mm) apart.

LTS150 and LTS300 Stages Mounted in XY Configuration Using LTSP1 Spacer Plate
The LTSP1(/M) is a spacer plate, allowing any two LTS translation stages to be mounted in an XY configuration. When assembled as shown to the right, the working height of the upper stage is 3.15" (80 mm). The spatial dimensions of the stage configuration will depend on the orientation (left-handed or right-handed) of the X and Y stages. Please contact Tech Support for the exact dimensions of a particular setup.

Two LTS150 Stages Mounted in XZ Configuration Using LTSP2 Bracket
The LTSP2(/M) right angle bracket allows an LTS150(/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 LTSP2(/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.
