XYZ Configuration Using Three LNR50M Stages with
LNR50P4 Base Plate and LNR50P2 Right-Angle Bracket
| TravelMax™ Crossed-Roller Bearing Stages Selection Guide | |
|---|---|
| Manual | 25 mm (1") Travel |
| 50.8 mm (2") Travel | |
| Motorized | 25 mm (0.98") Travel |
| 50 mm (1.97") Travel | |
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 engraved 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).

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).
