TravelMax Steel Stages
TravelMax series stages are equipped with actuator side clamps that are removable, thereby allowing any combination of manual, piezo extenders, or motorized actuators to be fitted. The stages featured here are shipped preconfigured with either a micrometer drive (LNR50M) or a differential drive (LNR50DD). A pre-configured Stepper Motor (LNR50S) option is also available. Alternatively, the stage can be purchased without drives; please contact Tech Support for a quote.

Although these stages are supplied pre-configured with an actuator, these can be easily replaced if the application requirements change. Please see our compatible actuators subgroup below 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 cross-roller bearings, provides uniform performance over the entire 2" (50 mm) range of motion.

XYZ Configuration Using Three LNR50M Stages with Base Plate LNR50P1 and Right-Angle Bracket LNR50P2

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

Wide Range of Mounting Options
The TravelMax was 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) 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.

LNR50P2 Right-Angle Bracket
LNR50P1
LNR50P1 Base Plate

The LNR50P1 base plate (shown in the photo to the left) 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 mentioned opposite to be attached directly. The plate measures 100 mm x 195 mm x 12 mm (3.9" x 7.7" x 0.47").

The LNR50P2 angle bracket (shown in the photo to the right) allows the LNR stage to be mounted vertically. When combined with the LNR50P1 described above, it can be used to build an XZ, YZ, or XYZ configuration.

The solidworks file for the LNR50P2 appears to have metric spaced holes for one of the two plates. I imagine these should have an inch-based hole spacing.

The SolidWorks file is correct. The only difference between the metric and imperial versions of this product is the two tapped holes which are M6 on the metric and ¼-20 UNC on the imperial. All hole spacing are the same. The holes are sized so that they can accommodate M6 screws on a 50mm pitch or ¼-20 UNC screws on a 2” pitch.

does this part come with a through hole in the middle so that I can shine optical stuff through it? Thanks

Response from Jeremy at Thorlabs: The LNR50 stage do not have a through hole in the middle. There are two through holes but those are for mounting the stage onto another surface.

TravelMax™ Stages - Compatible Actuators

Type Of Actuator Item # Travel Range
Manual
This Differential drive has been designed for use the TravelMax series stages, and provides 2.0" (50 mm) of coarse adjustment (500 µm per rev) and 300 µm of fine adjustment (50 µm per rev). The large diameter knob has graduations every 1.0 µm and allows precise, ultra-smooth control over the entire range of motion.

Open Loop Piezo
The PAS series Piezo Actuators provide adjustment lengths of 20 µm, 40 µm or 100 µm, at a resolution of 20 nm, 40 nm and 100 nm respectively. The drive voltage is 0 - 75 V. Thorlabs supplies a number of suitable piezo controllers such as our KPZ101 K-Cube™ piezo driver. Alternate drivers with a BNC connector can be used with the MDC40211 SMC-to-BNC adapter.

The actuator is shipped with a flat tip as shown, but can accept any of our PAA Series actuator tips.

Closed Loop Piezo
The PAZ series actuators has a travel length of 20 µm, 40 µm or 100 µm, at a resolution of 5 nm, 10 nm and 25 nm respectively. Feedback connection is provided via a 7 pin LEMO connector that can be used in conjunction with our APT series of motion controllers - see below. The drive voltage is 0 - 75 V. Thorlabs supplies a number of suitable piezo controllers such as our BPC301 benchtop piezo driver. Alternate drivers with a BNC connector can be used with the MDC40211 or T4292 SMC-to-BNC adapters.

Stepper Motor Drives
The DRV013 and DRV014 stepper motors offer 25 mm (1") or 50 mm (2") of travel, respectively, and a bidirectional repeatability better than 1 μm. When used with one of our BSC201, BSC202, or BSC203 Stepper Motor Controllers, a resolution better than 50 nm and a 20 mm/s maximum speed 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 25,600 steps 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 cleaner, more wear-resistant operation. The DRV013 and DRV014 are capable of driving loads as high as 48 lbs (22 kg) or 55 lbs (25 kg), respectively. The use of a trapezoidal lead screw provides a number of benefits over the more common Acme style thread, namely improved durability, a lower friction due to improved surface quality, and nearly no back-drive.
