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). Pre-configured motorized stages are 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.

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.

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 mm x 145 mm x 12 mm.

The LNR50P2 angle bracket allows the LNR stage to be mounted vertically. When combined with the LNR50P4 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.

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.	DRV8	50 mm (2")
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.	PAS005 PAS009 PAS015	20 µm 40 µm 100 µm
Closed-Loop Piezo The PAZ series actuators have a travel range of 20 µm, 40 µm, or 100 µm at a resolution of 5 nm, 10 nm, and 25 nm respectively. The drive voltage for these actuators is 0 - 75 V. Feedback connection is provided via a 7 pin LEMO connector that can be used in conjunction with our APT series of motion 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. The actuator is shipped with a flat tip as shown, but can accept any of our PAA Series actuator tips.	PAZ005 PAZ009 PAZ015	20 µm 40 µm 100 µm
Stepper Motor Drives The DRV225 and DRV250 stepper motors offer 25 mm (1") or 50 mm (2") 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.	DRV225 DRV250	25 mm (1") 50 mm (2")
