25 mm (0.98") Stepper Motor Translation Stage, Crossed Roller Bearings
25 mm (0.98") Stepper Motor Translation Stage
Two LNR25ZFS Stages Mounted in an XY Configuration on an LNR25P1 Base Plate
|Motorized Linear Translation Stages|
|Long Travel: 100 mm to 300 mm|
Wide Range of Mounting Options
The TravelMax™ was designed with flexibility and functionality in mind. The top surface of the LNR25ZFS stage is equipped with an array of seven 1/4"-20 (M6) tapped holes to maximize the mounting options for moving components. Two through holes in the top platform give access to two 1/4" (M6) counterbored holes that allow the stage to be bolted directly to the work surface. The position of the actuator mounting blocks is easily reconfigured to allow left-hand or right-hand use.
The LNR25P1 base plate, shown to the left, provides additional mounting options and provides extra clearance between the stage and the work surface. Counterbored clearance holes match up to the tapped holes in the base of the stage, permitting mounting in two orthogonal orientations. This plate is compatible with both the imperial and metric versions of the LNR25ZFS(/M) stage. The plate measures 100 mm x 195 mm x 10 mm (3.9" x 7.7" x 0.47") [L x W x H], ships with two dowel pins, and includes four alignment holes to ensure mounting orthogonality.
Multiple LNR25ZFS series stages can be bolted together in XY, XZ, YZ, or XYZ configurations for applications where movement is required in more than one axis. The LNR25P2 angle bracket, shown to the left, provides the vertical mounting necessary for movement in the Z direction. Again, this bracket is compatible with both the imperial and metric versions of the LNR25ZFS(/M) stage. The plate is shipped with four dowel pins and includes four alignment holes on each face to ensure orthogonality when mounting stages.
The LNR25ZFS stage is compatible with the KST101 K-Cube™ Stepper Motor Controller, available below. The KST101 provides control for a single axis, with or without a PC. Thorlabs' Kinesis® or legacy APT™ software packeges supply out-of-the-box stage control from a PC and enable support for common programming interfaces like LabVIEW, LabWindows, and ActiveX. Thorlabs' benchtop stepper motor controllers and legacy T-Cube™ TST001 stepper motor controllers cannot be used to drive the stage.
The ZFS series of motors has 24 full steps per revolution, and when driven by the KST101 drivers, there are 2048 microsteps per full step, giving 49,152 microsteps per revolution of the motor. The output shaft of the motor goes into a 400:9 gear head. This requires the motor to rotate 44.445 times to rotate the 1.0 mm pitch lead screw one revolution. The end result is the lead screw advances by 1.0 mm.
Linear displacement of the lead screw per microstep:
Number of Microsteps x Gearbox Ratio = 49,152 x 44.445 = 2184560.64
The linear displacement of the lead screw per microstep is
1.0 mm / 2184560.64 = 0.46 x 10-6 mm = 0.46 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.
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.
These videos illustrate some of the basics of using the APT System Software from both a non-programming and a programming point of view. There are videos that illustrate usage of the supplied APT utilities that allow immediate control of the APT controllers out of the box. There are also a number of videos that explain the basics of programming custom software applications using Visual Basic, LabView and Visual C++. Watch the videos now to see what we mean.

To further assist programmers, a guide to programming the APT software in LabView is also available.

Thorlabs' LNR25ZFS(/M) Stepper Motor Translation Stage provides 25 mm (0.98") of linear motion. An array of seven 1/4"-20 (M6) tapped holes allows easy integration with a wide variety of common optomechanical setups. The stage features rigid, all-steel construction and heavy-duty cross-roller bearings for excellent stability and high load capacity. The stage requires a controller unit and power supply to operate. For this purpose, we recommend our KST101 K-Cube™ Stepper Motor Controller, which is described in more detail below. A mounting base plate and a vertical mounting bracket for the stage are available below.
The LNR25P1 Base Plate and LNR25P2 Angle Bracket are mounting accesories for the LNR25ZFS(/M) Stage. The LNR25P1 base plate has four counterbored clearance holes for mounting the LNR25ZFS in two orthogonal orientations. The LNR25P2 angle bracket provides a vertical mounting surface for construction of an XZ, YZ, or XYZ configuration. These mounting accessories are compatible with both the imperial and metric versions of the translation stage.
Thorlabs' KST101 K-Cube™ Stepper Motor Controller provides local and computerized control of a single motor axis. It features a top-mounted control panel with a velocity wheel that supports four-speed bidirectional control with forward and reverse jogging as well as position presets. The digital display on the top panel includes a backlight that can be dimmed or turned off using the top panel menu options. The front of the unit contains two bidirectional trigger ports that can be used to read a 5 V external logic signal or output a 5 V logic signal to control external equipment. Each port can be independently configured.
Please note that this controller does not ship with a power supply. Compatible power supplies are listed below.
The KPS101 power supply outputs +15 VDC at up to 2.4 A and can power a single K-Cube or T-Cube with a 3.5 mm jack. It plugs into a standard wall outlet.
The KCH301 and KCH601 USB Controller Hubs each consist of two parts: the hub, which can support up to three (KCH301) or six (KCH601) K-Cubes or T-Cubes, and a power supply that plugs into a standard wall outlet. The hub draws a maximum current of 10 A; please verify that the cubes being used do not require a total current of more than 10 A. In addition, the hub provides USB connectivity to any docked K-Cube or T-Cube through a single USB connection.
For more information on the USB Controller Hubs, see the full web presentation.
