Compact Quick Connect Linear Stages, 25 mm Travel, Crossed-Roller Bearings![]()
XRN25C Compact 25 mm Stage with The XRN25P (left) is considerably more compact than the XR25P (right), but both provide a travel range of 25 mm. XRN25P-K2 Preassembled XYZ Stage Kit with Side Micrometers ![]() Please Wait
![]() Click to Enlarge The 2" female dovetails on the bottom of one stage mates with the male dovetail on the other to form XY stage configurations. The left female dovetail is on a retractable clamping arm, allowing stages to be dropped into place. Quickly Construct Multi-Axis Stages Each stage features 2" dovetails on the top and bottom plate that allow for quick construction of multi-axis systems. There are no dowel pins to install or screws that need to be inserted through the top plate, which means that mounted components do not need to be removed from the top stage before constructing an XY configuration. In addition, the top stage can be locked at any location along the dovetail, allowing for coarse positioning. Features
Thorlabs' XRN25 Series Compact Translation Stages provide 25 mm of linear translation with less than 150 µrad of deviation per axis in pitch and yaw over the full range of the stages. These stages use crossed-roller steel bearings to support precision motion and high load capacities. The top and bottom plates are machined from cast tool and jig aluminum for minimal internal stress and improved stability. Additional functionality is provided by a complete line of accessories that include multi-axis assembly kits, rail carriers, a rotation adapter, rails, and micrometer conversion kits. An adapter plate is also available for mounting these compact 25 mm stages with an integrated 2" dovetail onto 25 mm and 50 mm stages with a 3" dovetail.

Micrometer Conversion Procedure
![]() Click to Enlarge The side-mounted micrometer can be swapped with the locking plate to create both left-and right-handed stages. Micrometer Conversion Note: Before removing the micrometer, lock the stage by tightening the button head cap screw in the groove in the steel locking plate using a 5/64" (2 mm) hex key. Swapping a Side-Mounted Micrometer
Manual Linear Translation StagesThorlabs' 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 StagesThese linear translation stages feature crossed roller bearings 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 aluminum.
Ball Bearing StagesThese translation stages feature hardened steel linear bearings for precise motion and long life. They are available with a variety of actuators and in single-axis or preassembled multi-axis configurations.
Dovetail StagesThese compact stages incorporate dovetails and a leadscrew for the translation mechanism. They are suitable in general purpose motion control applications.
Flexure StagesThorlabs' 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.
Vertical StagesWe offer vertical translation stages with crossed roller bearings for precise motion as well as long travel vertical stages for heavy-duty applications.

The XRN25P(/M) and XRN25C(/M) stages are compact versions of our XR25 series quick connect stages. They provide 25 mm of travel and feature a side- or end-mounted metric micrometer, respectively, which gives a 500 µm displacement for each revolution. Stages are available with side-mounted micrometers for situations where space is a premium, and end-mounted micrometers for ease of adjustment. The stages are lockable with a plate on the side of the stage that can be locked using a 5/64" (2.0 mm) hex key. The top plate of each stage is tapped with an array of 1/4"-20 (M6) tapped blind holes. These stages can be easily stacked and secured to one another using the integrated 2" mating dovetails. The stages are secured by a single dovetail locking mechanism with a 3/16" (5 mm) hex key. Other multi-axis configurations are also possible as illustrated in the table below. Take care during assembly to ensure no collisions occur with the Z-axis stage during full downward extension. To purchase the necessary components, simply click on the product list and add the items to your cart. They can also be mounted to our 3" mating dovetail stages (25 mm and 50 mm) using the XRN-A1 adapter plate (sold below). Micrometer conversion kits are available below that can be used to convert a side- or end-mounted stage into an end- or side-mounted stage, respectively.

Thorlabs offers XRN25P(/M) stages preassembled in XY and XYZ configurations. The XRN25P-K1(/M) Preassembled XY Stage consists of two XRN25P(/M) stages preassembled in an XY configuration. The XRN25P-K2(/M) Preassembled XYZ Stage consists of three XRN25P(/M) stages preassembled in an XYZ configuration using an XRN-XZ(/M) Assembly Kit. The XRN25P-K2 eliminates the need to buy and manually assemble the multi-axis stage assembly kits, which are sold below. Each stage features a side-mounted metric micrometer for 25 mm of travel at 500 µm translation per revolution. The XRN25P offers 1/4"-20 tapped mounting holes, while the XRN25P/M offers M6-tapped mounting holes. The micrometer can be moved to the opposite side of the stage by swapping the micrometer mounting blocks with the steel locking plate. For more information, please see the Micrometer Conversion tab above. Micrometer conversion kits are available below that can be used to convert an end- or side-mounted stage into a side- or end-mounted stage, respectively. ![]() ![]() Click to Assemble YZ Stage Assembly Constructed Using the XRN-YZ Assembly Kit ![]() Click to Enlarge Vertical X-Axis Stage Constructed Using the XRN-XZ Assembly Kit and the XRN-B1 Base Plate (Sold Below)
Thorlabs offers two assembly kits used to mount two XRN25 series stages perpendicular to each other. The XRN-XZ(/M) Assembly Kit contains a mounting plate and an angle bracket that mounts the surface of the Z-axis platform in-line to the direction of travel (XZ configuration). The XRN-YZ(/M) Assembly Kit contains a mounting plate and an angle bracket that mounts the surface of the Z-axis platform perpendicular to the direction of travel (YZ configuration). Take care during assembly to ensure no collisions occur with the Z-axis stage during full downward extension. Both configurations require purchasing two XRN25C(/M) or XRN25P(/M) stages in any combination as well as either assembly kit. The female dovetail on one arm of the angle bracket attaches to the male dovetail on the tapped platform of the X- or Y-axis stage, and then the male dovetail of the tapped platform of the Z-axis stage is mated to the other arm of the angle bracket. The tapped mounting plate provided with the XRN-XZ and the XRN-YZ is mounted to the Z-axis stage by attaching the male dovetail of the plate to the female dovetail on the stage, as shown in the image to the right. Mating the Z-axis stage this way ensures that the micrometer is countering forces from both gravity and the internal spring.

These adapters enable mounting of quick connect, crossed-roller bearing stages or accessories with a female 2" dovetail to components with a male 3" dovetail, as illustrated in the photos below. The XRN-A1 adapter enables perpendicular mounting while the XRN-A2 enable parallel mounting. The mounting configuration in the second photo below allows translation along the extended dovetail to be parallel to the direction of translation of a mounted stage. To assemble, first loosen the dovetail locking screw on the end of the top stage or accessory. Position the adapter on the bottom stage or rail, as illustrated in the photos below, then align the top component on the adapter. Lastly, tighten the dovetail locking screw (maximum torque: 15 in•lbs) on the end of the top component until the entire assembly is secure. Please note that the deep-set screws in the sides of the adapter are not user adjustable.
