![]() Click to Enlarge The 3" 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 3" 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' XR25 Series 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. The top and bottom of each stage feature quick connect dovetails (as shown in the image above) that allow for the construction of multi-axis systems without the need for additional hardware. The stages are locked into place via a lock plate that accepts a 5/64" (2.0 mm) hex key or ball driver. See the animation to the lower right to see how multi-axis systems can be quickly constructed using this novel design. The 3" dovetails on our XR25 series stages are directly compatible with the dovetails on our XR50 series translation stages and our XRR1 rotation stage. Additional functionality is provided by a complete line of accessories that include multi-axis assembly kits, rail carriers, rotation adapter, rails, stage positioners, and micrometer conversion kits. These accessories are compatible with all stages that have an integrated 3" dovetail. An adapter plate for mounting compact 25 mm stages with an integrated 2" dovetail onto stages with a 3" dovetail is also available. For more information about a specific accessory, please click on the link in the table below.
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 XR25P(/M) and XR25C(/M) stages 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 end of each micrometer incorporates a 5/64" (2 mm) hex allowing it to be actuated in space-constrained environments. 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. 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 XR25P(/M) stages preassembled in XY and XYZ configurations. The XR25P-K1(/M) XY Stage consists of two XR25P(/M) stages preassembled in an XY configuration. The XR25P-K2(/M) XYZ Stage consists of three XR25P(/M) stages preassembled in an XYZ configuration using an XR25-XZ(/M) Assembly Kit. The XR25P-K2 eliminates the need to buy and manually assemble the multi-axis stage assembly kits, which are sold below. Each XR25P(/M) stage features side-mounted metric micrometers for 25 mm of travel at 500 µm translation per revolution. The XR25P offers 1/4"-20 tapped mounting holes, while the XR25P/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 Enlarge Z-Axis Stage Constructed Using the XR25-XZ Assembly Kit and the XR25-B1 Base Plate (Sold Below)
Thorlabs offers two assembly kits used to mount two XR25 or XR50 series stages perpendicular to each other. The XR25-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 XR25-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 XR25 and/or XR50 series 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 XR25-XZ and the XR25-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. The tapped mounting plate included in each assembly kit contains the same 1/4"-20 (M6 x 1.0) tapped hole pattern as the top plate of the stages. Additionally, it offers two rear-located #8 (M4) counterbores for mounting optomechanical components with tapped 8-32 (M4) mounting holes directly to the mounting surface. Note that the component must be mounted with the 8-32 (M4) cap screw before the mounting plate is secured to the stage. Z-Axis Stage Configuration X-Axis Stage Configuration XYZ Configurations ![]()
These adapters provide additional mounting options for our quick-connect, crossed-roller bearing stages, as illustrated in the photos below. The XRN-A1 adapter enables perpendicular mounting of components with a female 2" dovetail to components with a male 3" dovetail. The XR25-A2 adapter enables parallel mounting of two components with 3" dovetails. The mounting configuration in the second photo below allows translation along a rail 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.
