Thorlabs' LTS450C(/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 450 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 a calibrated on-axis accuracy of <±5 µm when the unit-specific calibration files are used with either the Thorlabs Kinesis or XA 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.

Other Translation Stages

The LTS450C(/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 Figure 1.1). 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 6.0 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 LTS150C(/M) and LTS300C(/M) Linear Translation Stages with Integrated Controllers, which feature 150 mm or 300 mm of travel, respectively.

Calibration Files
Each LTS450C(/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 XA 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 LTS150C(/M), LTS300C(/M), and LTS450C(/M) Linear Positioning Stages (featuring a 150 mm, 300 mm, or 450 mm travel range, respectively) can be mounted atop one another using the LTSP1(/M) XY Adapter Plate (sold below). XZ and XYZ configurations for the LTS150C(/M) and LTS300C(/M) stages are possible using our LTSP3(/M) Z-Axis Bracket, which orients the 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.

Software
Thorlabs offers the Kinesis^® and XA software packages to drive our wide range of motion 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 LTS450C(/M) stages with any benchtop, tabletop, or rack-based controllers.

Notes

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.
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.

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 and goniometers. We also offer manual translation stages.

Piezo Stages

These stages incorporate piezoelectric elements in a variety of drive mechanisms. ORIC^® stages incorporate piezo inertia drives that use "stick-slip" friction properties to obtain extended travel ranges. Our Nanoflex™ translation stages use standard piezo chips along with manual actuators. Elliptec^® stages use resonant piezo motors to push and pull the moving platform through resonant elliptical motion. Our LPS710E z-axis stage features a mechanically amplified piezo design and includes a matched controller.

Additional Details

For a given set of settings in Kinesis, while travelling in one direction, each device's step size may vary by up to 20% and is not normally repeatable. Due to the open loop design, component variance, change of direction and application conditions may further increase the scale of the variance.
The PIA25 piezo inertia actuator is ideal for set-and-hold applications that require high-resolution relative positioning.
For position readouts with 10.0 µm accuracy, we offer the ENCXR25 optical encoder (sold separately).

Stepper Motor Stages

These translation stages feature removable or integrated stepper motors and long travel ranges up to 300 mm. Many of these stages either have integrated multi-axis capability (PLSXY) or can be assembled into multi-axis configurations (PLSX, LNR Series, NRT Series, and LTS Series stages). The MLJ150 stage also offers high load capacity vertical translation.

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.

Communications Protocol

Figure 789A Kinesis GUI Screen

Thorlabs offers two platforms to drive our wide range of motion controllers: our XA software package and our Kinesis software package, which is being phased out. The Kinesis software supports most of Thorlabs' motion control products. The XA software is an improved platform for developers that currently supports some of our most popular motion control products (see the full list of supported products here). The software is undergoing continuous, intensive development and will eventually add support for our entire line of motion control products. The XA software application will be fully supported through the year 2040.

Kinesis Motion Control Software

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.

By providing a common software platform, Thorlabs has ensured that users can easily mix and match any of the Kinesis 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.

Figure 789B XA GUI for KDC101 Brushed DC Servo Controller

The software package allows 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.

XA Motion Control Software: Improved Platform for Developers

Designed from the ground up to be straightforward to understand, XA provides a thread-safe and language-paradigm-agnostic set of application programming interfaces in C, C++, and C#/.NET with language wrappers available to allow for easy integration into your native, .NET language, Python, or LabVIEW applications. This enables the same functionality as mentioned for the Kinesis software development kit (SDK) while providing a more streamlined toolkit for developers. Coupled with the included developer guides and code examples in the SDK, this software is tailored toward users interested in creating complex, customized applications and interfaces. Full API documentation is provided for the native C library, and the .NET wrapper documentation is currently under development. Please contact Tech Support for more details on using the .NET wrapper.

XA also features a comparable GUI to Kinesis while adding improvements to the user experience, like the ability to save device states and a more consistent interface across devices of different types. In addition, further improvements are planned as XA will be fully supported through the year 2040, whereas the Kinesis software is being phased out. The current version of the XA software can only drive select Thorlabs motion controllers. However, the software is undergoing continuous, intensive development and will eventually add support for our entire line of motion control products. Information on software compatibility can be found in the XA User Guide, and additional details about the software, including a list of compatible devices, can be found here.
