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.

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.

The side-mounted micrometer can be swapped with the locking plate to create both left-and right-handed stages.
Micrometer Conversion
The video to the left outlines how to convert an end-mounted micrometer stage (XR25C or XR50C) to a side-mounted micrometer stage (XR25P or XR50P) using the XR25-C1 conversion kit. To convert a side-mounted micrometer stage to an end-mounted micrometer stage, simply follow the directions in reverse and use the XR25-C2 conversion kit.
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
If you would like to switch the location of the locking plate, as shown in the photo to the right, retract the micrometer to the end of the travel range before removing all three button head screws from the locking plate. Failure to do this will cause the stage to quickly retract to its minimum position when the micrometer is removed, potentially damaging the mechanism.
Video Insight Clip: Replacing the Actuator on a Thorlabs XR Linear Translation Stage
This Video Insight clip demonstrates how to replace the included manual actuator on a Thorlabs XR translation stage by a motorized actuator for remote operation. When making such a replacement, be sure to verify compatibility between the travel range and mounting barrel size of the motorized actuator and the XR translation stage. For more details on installing a motorized actuator, you can find the full Insight here.
If you would like more information about tips, tricks, and other methods we often use in the lab, we recommend our other Video Insights. In addition, our webinars provide practical and theoretical introductions to our different products.

We will also go ahead and post this on our internal engineering forum so that we can potentially offer this as a stock part in the future. reparks
(posted 2017-12-16 08:47:52.613) This is the only Thor product that I have been truly disappointed in. When the stages are stacked it is very difficult to read the micrometers. When I went to substitute Mitutoyo digital mics, the standoff clamp is too close to the slide for the micrometer to fit. And when I went to replace the original micrometer the screw thread stripped so I could no longer secure the micrometer. I think the clamp screws are too small for their intended job.
If you would I would like you to send me a new micrometer clamping block so I can restore the function of this stage. I admit that if I had purchased the XR25C this problem would not have arisen but who wants micrometers sticking out in all directions on stacked stages. tfrisch
(posted 2017-12-19 03:14:19.0) Hello, thank you for contacting Thorlabs. I see you have already been in contact with one of our design engineers about the change that lengthened the clamp screw to provide more thread engagement. Furthermore, the digital micrometers would be easiest to read on an end-actuated stage, but as you noted, that isn't compact, so we can discuss alternatives for that as well. |
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 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.

Z-Axis Stage Constructed Using
the XR25-XZ Assembly Kit and
the XR25-B1 Base Plate (Sold Below)
- Kits Consist of Angle Bracket and Z-Axis Mounting Plate
- Supports X, Z, XZ, YZ, or XYZ Configurations
- Compatible with 3" Mating Dovetail Stages
- Included Dovetail Clamp Screw has a Maximum Torque of 15 in•lbs
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
For situations where only a Z-axis translation stage is needed, either the XR25-XZ or the XR25-YZ angle bracket can be secured directly to the XR25-B1(/M) base plate (sold below), as shown in the figure to the right.
X-Axis Stage Configuration
In addition to a Z-axis stage configuration, the XR25-XZ can be used for situations where the X-axis translation stage needs to be mounted vertically. The X-axis stage needs to be secured to the XR25-XZ angle bracket, and the angle bracket secured directly to the XR25-B1 base plate (sold below).
XYZ Configurations
In order to construct an XYZ configuration, first construct an XY stage as pictured in the sample configuration table above. Then, the XR25-YZ assembly kit can be used to add the Z-axis. An XYZ configuration can also be constructed using the XR25-XZ assembly kit, which functions the same as an XYZ configuration constructed using the XR25-YZ, with only the X-axis and Y-axis stages switched. An XYZ configuration using the XR25-XZ assembly kit is shown to the right.
Zoom- XRN-A1 Adapter Enables Perpendicular Mounting of 2" Dovetail Components onto 3" Dovetail Components
- XR25-A2 Adapter Enables Parallel Mounting of 3" Dovetail Components
- Adapters Add 0.275" (7.0 mm) to the Overall Stacked Height of Components
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.

Zoom- Allows for Coarse Rotational or Translational Alignment of Stages with Table Hole Matrix
- Orthogonal Male Dovetails for Two Stage Mounting Orientations
- Compatible with 3" Mating Dovetail Stages
The XR25-B1(/M) Base Plate provides an additional table mounting option for our XR25 and XR50 series translation stages. The base plate features two orthogonal male dovetails that allow for two mounting orientations of an XR25 or XR50 series stage. A center Ø1/4" (M6) counterbored hole and two radial counterbored slots allow for
coarse angular adjustment with respect to the table's 1/4"-20 (M6 x 1.0) hole matrix. For situations where the stage is oriented with the table's hole matrix, two 2.2" (55.9 mm) long 1/4" (M6) counterbored slots on the edge of the base plate allow for coarse translation adjustment along the hole matrix before the base is secured to the table.
Z-Axis Stage Configuration
For situations where only a Z-axis translation stage is needed, either the XR25-XZ or the XR25-YZ angle bracket (sold above) can be secured directly to the base plate.
X-Axis Stage Configuration
In addition to a Z-axis stage configuration, the XR25-XZ angle bracket (sold above) can be used for situations where the X-axis translation stage needs to be mounted vertically. The XR25-XZ angle
bracket can be secured directly to the XR25-B1(/M) base plate.
This animation shows how the XR25-B1 base plate can be used for alignment of the stage.
