The 3" wide 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.

Each stage also features mating female dovetails on the bottom plate and male dovetails on the top plate that allow for quick construction of multi-axis systems using no 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, baseplates, stage positioners, and micrometer conversion kits. These accessories are compatible with all stages that have an integrated 3" wide dovetail. An adapter plate for mounting compact 25 mm stages with an integrated 2" wide dovetail onto stages with a 3" wide dovetail is also available. For more information about a specific accessory, please click on the link in the table below.

Micrometer Conversion Procedure
Compact 25 mm Translation Stage
Click to Enlarge

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.

It would be good to have 6" long baseplates, sometimes 12" baseplates don't fit in small spaces.

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.

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.

The side-mounted micrometer can be swapped with the locking plate to create both left-and right-handed stages. See the Micrometer Conversion tab for more details.
  • Side- or End-Mounted Metric Micrometer
  • Mounting Surface has Twenty-Two 1/4"-20 (M6) Tapped Blind Holes, 0.30" (7.6 mm) Deep
  • Create Multi-Axis Configurations Using Dovetail Locking Screw
    • Clamp Screw has a Maximum Torque of 15 in•lbs
  • Directly Compatible with 3" Wide Mating Dovetail Stages:

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.

These stages can be easily stacked and secured to one another using the integrated 3" wide 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.

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.

  • Kits Consist of Angle Bracket and Z-Axis Mounting Plate
  • Supports X, Z, XZ, YZ, or XYZ Configurations
  • Compatible with 3" Wide 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) 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) baseplate (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 baseplate (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.

Thorlabs offers three rail carriers that are directly compatible with our XR25 and XR50 series stages, providing coarse translation in addition to the fine translation supplied by the stage's micrometer, as well as expanding the stages' threading options for optomechanical assemblies. A female dovetail allows each rail carrier to slide onto an XR25 or XR50 series stage and connect to the stage's male dovetail. The position of the carrier can then be locked into place using a clamping mechanism [3/16" (5 mm) hex] located on one end of the carrier. This simple procedure allows the user to seamlessly swap and install different carriers on a stage in a matter of seconds.

Side Located Locking Screws for Clamping Adapter (left) and Locking Rotation (right)
  • 360° Coarse Rotation Adjustment
  • Top Plate with 1/4"-20 and 8-32 Tapped Holes
  • Base Plate Provides Ø1" Flexure Clamp
  • Purchase Complete Adapter or Separate Base Plate
  • Compatible with 3" Wide Mating Dovetail Stages
  • Included Dovetail Clamp Screw has a Maximum Torque of 15 in•lbs

The XR25-R1(/M) Rotation Adapter allows users to mount any two 3" dovetail components together on a rotational axis perpendicular to their mounting surfaces. This allows a full 360° range of coarse rotation. The removable top plate features thirteen 1/4"-20 (M6) and twelve 8-32 (M4) tapped holes in addition to the 3" wide male dovetails on all edges. Rotation is achieved by loosening the right-most locking screw on the baseplate (also sold separately as the XR25-RB) using a 3/16"(5 mm) hex key. The adapter is clamped in place to a 3" dovetail with the left-most locking screw using a 3/16" (5 mm) hex key. These screws can be seen in the image above. 

If the XR25-R1 is used to mount a stage vertically, that stage should not be rotated where the spring tension is working against gravity. Rotation in this configuration should be limited to 180°. In addition, note that the XR25-R1 is a two-piece solution where the top plate is not permanently retained in the base, and therefore care should be taken when loosening the rotation locking screw in a vertical orientation.

The XR25-RB(/M) Adapter Base Plate can be purchased separately. Utilizing its flexure clamp for 1" (25.0 mm) outer diameter components, like our Ø1" Optical Posts or our Ø1/2" Post Holders, allows the rotation adapter base plate to double as a rail carrier, as seen in the image to above. Here, the coarse height of the KS1 mirror mount can be adjusted with the PH2 post holder, while the coarse rotation can be independently adjusted in the rail carrier. This base plate also includes three 8-32 mounting holes on the face opposite the adjustment screws and integrated steel pads on its sides for use with the XR25-RC3 hard stop.

The XR25-A2 adapter enables parallel mounting of two components with 3" wide dovetails. 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 baseplate, 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.

Baseplate with Rotational Adjustment

  • Allows for Coarse Rotational or Translational Alignment of Stages with Table Hole Matrix
  • Orthogonal Male Dovetails for Two Stage Mounting Orientations
  • Compatible with 3" Wide Mating Dovetail Stages

The XR25-B1(/M) Baseplate provides an additional table mounting option for our XR25 and XR50 series translation stages. The baseplate 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) 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 baseplate 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 baseplate.

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) baseplate.


This animation shows how the XR25-B1 baseplate can be used for alignment of the stage.

Baseplates with Extended Linear Positioning


Click to Enlarge

When mounted on the extended baseplate, the stage's translation axis is perpendicular to the adjustment axis of the baseplate.
  • Allows for Coarse Adjustment Perpendicular to Stage Translation Axis
  • 150 mm, 250 mm, and 500 mm Lengths Available
  • Counterbored Mounting Slots Compatible with Imperial and Metric Breadboards
  • Outer Dovetail Compatible with 3" Wide Mating Dovetail Stages
  • Additional Dovetail Compatible with 34 mm Rail Accessories

These Extended Baseplates provide a convenient way to mount our XR25 and XR50 series translation stages on a breadboard or optical table. Both baseplates feature an outer male dovetail for mounting the translation stage, as shown in the image to the right, and an inner 34 mm male dovetail for mounting other clamps and platforms.

A mounted component can be translated across the entire length of the baseplate. The XR25DR2, XR25DR, and the XR25DR3 come in lengths of 150 mm, 250 mm, and 500 mm, respectively. For these stages, travel along the rail would be in the direction orthogonal to the stage's translation axis. The graduated scale engraved along one edge of each baseplate makes it easy to repeat adjustments between multiple locations on the baseplate; the XR25-RC3 rail carriers sold above can be used to mark a specific location on the baseplate before moving the stage. Note that our XRN-A2 adapter (sold below) can be used to mount XRN25 series stages in parallel to the extended baseplate. The XR25-A2 adapter can be used to achieve the same parallel mounting orientation with our XR25 series stages.

The baseplates feature 1" long 1/4" (M6) counterbored mounting slots and a central 1/4" (M6) counterbored mounting hole that allow the rail to be used with both imperial and metric breadboard hole patterns. Standard cap screws can be used with this baseplate without interrupting the translation of mounted components.

Translation Stage Positioners


Click to Enlarge

The XR25N Positioner and XR25N1 Return Positioner can provide fine alignment of translation stages mounted on an extended dovetail baseplate.
  • Clamps Directly to 3" Wide Mating Dovetails
  • Included Dovetail Clamp Screw has a Maximum Torque of 15 in•lbs
  • Fine Positioning of Stages and Carriers Along an Extended Dovetail Baseplate
  • XR25N Positioner:
    • 1/4"-80 Adjuster Screw Provides 0.013" (320 µm) of Translation per Revolution
    • Translation Range of 1.49" (37.8 mm)
  • XR25N1 Return Positioner:
    • Spring Loaded Plunger with Travel Range of 0.29" (7.2 mm)
    • Use with XR25N Positioner for Bidirectional Adjustment

The XR25N Translation Stage Positioner and XR25N1 Translation Stage Return Positioner are designed to aid in fine alignment of stages or carriers mounted on an extended dovetail baseplate. Each positioner includes a 3" wide mating dovetail that can be locked to the extended baseplate using a clamping mechanism [3/16" (5 mm) hex], providing quick and convenient placement along the rail. The end opposite the clamp also offers two 8-32 (M4) mounting holes.

The XR25N incorporates an F25SS200 1/4"-80 adjuster screw to provide smaller, smoother movement than coarse translation by hand. The screw allows for 1.49" (37.8 mm) of travel before the interior of the bushing is exposed; longer adjuster screws can be installed if desired.

The XR25N1 translation stage return positioner is comprised of a spring-loaded plunger integrated into a 3" mating dovetail clamp. The plunger can travel a maximum range of 0.29" (7.2 mm), and the compression spring tension can also be adjusted with a 5/32" (4.0 mm) hex driver. When used in conjunction, the XR25N positioner and XR25N1 return positioner provide precision alignment along the axis of the extended rail baseplate. When a carrier or stage is placed between the translation stage positioners, actuating the adjustment screw pushes it toward the XR25N1 return positioner, compressing the spring loaded plunger. Retracting the adjustment screw on the XR25N positioner causes the spring-loaded plunger on the XR25N1 return positioner to expand, which keeps the carrier or stage in contact with the actuating screw of the XR25N positioner.

To use, place and lock the positioners along the rail so that they are both in contact with the stage or carrier. Loosen the clamp holding the stage or carriage to the rail, then turn the adjuster screw with a 5/64" (2.0 mm) balldriver to push the platform until the desired amount of translation is achieved.
