TravelMax™ series stages are equipped with actuator side clamps that are removable, thereby allowing a variety of manual, piezo extenders, or motorized actuators to be fitted. The stages featured here are shipped preconfigured with either a micrometer drive (Item # LNR50M) or a differential drive (Item # LNR50DD). Pre-configured motorized stages are also available. Alternatively, the stage can be purchased without drives; please contact Tech Sales for a quote. Please refer to the Other Drives tab for details of other compatible actuators such as motor or piezo drives.

These stages offer stability, long travel, and high load capacity as well as flexible drive options, making them an ideal solution for all translation applications. Designed with the highest quality linear rails available, the performance is further enhanced by utilizing thermally matched materials that ensure stability, even in less-than-ideal conditions. The rigidity of the all-steel construction, along with the heavy-duty crossed-roller bearings, provides uniform performance over the entire 50.8 mm (2") range of motion.

Actuator Options
Two drive options are available depending on application requirements. The standard micrometer supplied with the LNR50M stage provides a 50.8 mm (2") range with a thread pitch of 0.1 mm. The Vernier scale provides graduations every 10 µm. The LNR50DD stage is equipped with a differential drive. The coarse adjustment provides 0.5 mm per revolution while the fine adjustment provides 50 μm per revolution. The fine adjuster on the differential drive has graduations every 1 µm.

For applications requiring fine positioning, the removable static pin that provides a stop for the stage's actuator can be replaced by a piezo drive. Combining the standard manual actuator with a piezo drive allows for both long travel and fine adjustment. Both open-loop and closed-loop piezo drives are available with 20 µm to 100 µm of travel and resolution as low as 5 nm.

Encoder Option
The ENCLNR50 Optical Encoder can be mounted to the LNR50 series translation stages and provides positional information in either inches or millimeters to a resolution of 1.0 µm and an accuracy of 10.0 µm.

Wide Range of Mounting Options
TravelMax stages were designed with flexibility and functionality in mind. The top and bottom surfaces of the LNR series of stages are equipped with a wide array of 1/4"-20 (M6 x 1.0) tapped holes to maximize the mounting flexibility of components. Two counterbored clearance holes are present in the moving world to allow the stage to be bolted easily to the work surface in either a left- or right-handed configuration.

The LNR50P2 Right-Angle Bracket allows the LNR50 stage to be mounted vertically. When combined with the LNR50P4 Base Plate, it can be used to build an XZ, YZ, or XYZ configuration. The LNR50P4 Base Plate provides additional mounting options and provides extra clearance between the stage and the work surface (e.g., when fitting motor drives).

The DRV225 and DRV250 Stepper Motors offer 25 mm (0.98") or 50 mm (1.97") of travel, respectively. When used with one of our BSC201, BSC202, or BSC203 Stepper Motor Controllers, a resolution better than 50 nm can be achieved. The hybrid stepper motor has a rotor that consists of 50 individual magnetic teeth, which is ideally suited for micro-stepping applications. With 409 600 microsteps per revolution, micro-stepping also ensures smooth low-speed motion with low vibrational noise. Each stepper motor drive is equipped with a trapezoidal screw thread for more efficient high-load operation than is available from a standard threading.

Alternate drivers with a BNC connector can be used with the MDC40211 or T4292 SMC-to-BNC adapters. The actuator is shipped with a flat tip as shown, but can accept any of our PAA Series actuator tips.
  • A primary actuator is required for the operation of each LNR50 series stage. A secondary piezo actuator is optional and supplements the primary actuator's travel range with additional fine positioning abilities; the piezo actuator is installed in place of the removable static pin that provides a stop for the stage's primary actuator.

Manual Linear Translation Stages

Thorlabs' manual translation stages are offered in a range of maximum travel distances, from less than 1/4" (6 mm) to 2" (50 mm) and longer for our long travel, large area platforms. Many of these stages can be ordered 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 manual translation stages. In addition to linear translation stages, we offer rotation stages, pitch and yaw platforms, and goniometers. We also offer motorized translation stages that are powered by DC Servo motors, stepper motors, or direct drive technology.

Crossed-Roller Bearing Stages

These linear translation stages feature crossed-roller bearing travel mechanisms for precision motion, high load capacity, and low angular deviation. The LNR Series stages feature all-steel body construction, while the LX, XRN, and XR Series stage bodies are constructed of cast tool and jig aluminum. We also offer several vertical crossed-roller bearing stages (see below).

Flexure Stages

Thorlabs' Nanoflex™ translation stages feature frictionless flexure mechanisms for improved positioning and resolution when compared to similar stages made using bearings. The translation of the stage is accomplished by the elastic deformation (flexing) of a linkage attached to the mounting platform. Most models also include piezo actuators for small position adjustments.

  • Remote Control via USB and Kinesis Software
  • Includes 1 m USB Cable (DS5 Power Supply Sold Separately)

The ENCLNR50 Stage Position Encoder is designed for our LNR50 series translation stages and provides positional information in either inches or millimeters to a resolution of 1.0 µm and an accuracy of 10.0 µm. The module is comprised of the optical encoder scale bracket that attaches directly to the stage and the position reader assembly which is then attached to the bracket, as illustrated in the animation below. The module is powered via a USB micro-B connection. A 1 m long USB type A to micro-B cable is included in the kit, but the DS5 power supply is sold separately. In addition to power, the USB connection also enables the encoder module to display the stage position and control the unit via our Kinesis software. We also offer the ENCXR50 position encoder for XR50 series stages, and ENCXR25 position encoder for the XR25 series stages.

The encoder must be installed on the same side of the stage where the lock plate is initially installed, on the side opposite the adjustment knob, as shown in the photo to the right. The lock plate must first be removed before mounting the encoder.

XYZ Configuration Using Three LNR50M Stages with
LNR50P4 Base Plate and LNR50P2 Right-Angle Bracket
  • Mount an LNR50 Series Translation Stage in the Vertical Plane
  • Dowel Pin Holes to Ensure Orthogonality (6 Dowel Pins Included)
  • Dimensions (L x W x H): 108.0 mm x 88.0 mm x 133.5 mm (4.25" x 3.46" x 5.26")

The LNR50P2(/M) Right-Angle Bracket allows an LNR50 series stage to be mounted vertically. When combined with the LNR50P4 Base Plate, it can be used to build an XZ, YZ, or XYZ configuration.

The base of the bracket contains six counterbored holes for 1/4"-20 (M6 x 1.0) cap screws, allowing it to be attached to the top of an LNR50 series stage or directly to an optical table. The vertical side has two 1/4"-20 (M6 x 1.0) tapped holes and eight Ø0.28" (7.0 mm) through holes.

The XYZ assembly shown to the right was constructed using the LNR50P2 Right-Angle Bracket, LNR50P4 Base Plate, and three LNR50M translation stages. Dowel pins are included with the base plate and right-angle bracket to assist in alignment of the stage.

Base Plate

  • Provides Additional Clearance Between the Stage and the Work Surface
  • Dowel Pin Holes to Ensure Orthogonality (2 Dowel Pins Included)
  • Made from Aluminum Alloy

The LNR50P4 base plate provides additional mounting options and provides extra clearance between the stage and the work surface (e.g., when fitting motor drives). Tapped holes match up to the two counterbored clearance holes mentioned above, and four slotted holes allow the LNR50P2 angle bracket to be attached directly. The base plate measures 100.0 mm x 145.0 mm x 12.0 mm (3.94" x 5.71" x 0.47").
