The 2" 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 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.

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.

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 2" dovetails on our XRN25 series stages are directly compatible with the dovetails on our XRNR1 rotation stage.

Additional functionality is provided by a complete line of accessories that include multi-axis assembly kits, rail carriers, a rotation adapter, baseplates, and micrometer conversion kits. An adapter plate is also available for mounting these compact 25 mm stages with an integrated 2" wide dovetail onto 25 mm and 50 mm stages with a 3" wide dovetail. 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 a rear-mounted micrometer stage (XRN25C and XRN25C/M) to a side-mounted micrometer stage using the XRN-C1 conversion kit. To convert a side-mounted micrometer stage (XRN25P and XRN25P/M) to a rear-mounted micrometer stage, simply follow the directions in reverse and use the XRN-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, back out the micrometer to the 25 mm reading 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.

Is it possible to convert the XRN25 stages to differential micrometer screws?
llamb  (posted 2018-03-01 08:24:57.0)
Hello Chris, thank you for contacting Thorlabs. Yes, it is possible to convert the XRN25 stages to have differential micrometers, as long as the differential micrometers have a Ø3/8" (Ø9.5 mm) mounting barrel. Side-mounted micrometers, like on the XRN25P(/M), will have limited mounting space. I will reach out to you directly to discuss this further.

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 Seventeen 1/4"-20 (M6) Tapped Blind Holes, 0.30" (7.6 mm) Deep
  • Create Multi-Axis Configurations Using Dovetail Locking Screw
    • Dovetail Clamp Screw has a Maximum Torque of 15 in•lbs
  • Compatible with 2" Wide Mating Dovetail Accessories

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" 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. They can also be mounted to our 3" wide 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.

  • Supports X, Z, XZ, YZ, or XYZ Configurations
  • Compatible with 2" 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 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.

Z-Axis Stage Configuration
For situations where only a Z-axis translation stage is needed, either the XRN-XZ or the XRN-YZ angle bracket can be secured directly to the XRN-B1(/M) baseplate (sold below). An image of this configuration is shown in the sample configuration table above.

X-Axis Stage Configuration
In addition to a Z-axis stage configuration, the XRN-XZ can be used for situations where the X-axis translation stage needs to be mounted vertically. As shown in the figure to the right, the X-axis stage needs to be secured to the XRN-XZ angle bracket, and the angle bracket secured directly to the XRN-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 XRN-XZ assembly kit can be used to add the Z-axis. An XYZ configuration can also be constructed using the XRN-YZ assembly kit, which functions the same as an XYZ configuration constructed using the XRN-XZ, with only the X-axis and Y-axis stages switched. An XYZ configuration using the XRN-YZ assembly kit is shown to the right.

  • Compatible with 2" Wide Mating Dovetail Stages
  • Included Dovetail Clamp Screw has a Maximum Torque of 15 in•lbs

The XRN-R1(/M) Rotation Adapter allows users to mount any two 2" (50.8 mm) 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 five 1/4"-20 (M6) and four 8-32 (M4) tapped holes in addition to the 2" wide male dovetails on all edges. Rotation is achieved by loosening the right-most locking screw on the baseplate (also sold separately as the XRN-RB) using a 3/16" (5.0 mm) hex key. The adapter is clamped in place to a 2" dovetail with the left-most locking screw using a 3/16" (5.0 mm) hex key. These screws can be seen in the image above.

If the XRN-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 XRN-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 XRN-RB(/M) Adapter Base Plate can be purchased separately. This flexure clamp allows the rotation adapter base plate to double as a rail carrier for components with a 1/2" (12.7 mm) diameter, as seen in the image above and to the right. Additionally, with the use of the AD12BA, components with a 12 mm diameter, such as our Ø12 mm optical posts, can also be used.

Mounting Adapters

  • XRN-A1 Adapter Enables Perpendicular Mounting of 2" Wide Dovetail Components onto 3" Wide Dovetail Components
  • XRN-A2 Adapter Enables Parallel Mounting of 2" Wide Dovetail Components onto 3" Wide Dovetail Components
  • Adapters Add 0.275" (7.0 mm) to the Overall Stacked Height of Components

These adapters enable mounting of quick-connect, crossed-roller bearing stages or accessories with a female 2" wide dovetail to components with a male 3" wide 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 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.

Stage Baseplate

Compact 25 mm Stage Mounting Plate
Click to Enlarge

The orthogonal dovetails on the top of the XRN-B1 allow the stage to be mounted in two orientations.
  • 1.26" Long, 1/4" (M6) Counterbored Slots for Additional Mounting Flexibility
  • Orthogonal Male Dovetails for Two Stage Mounting Orientations
  • Compatible with 2" Wide Mating Dovetail Stages

The XRN-B1(/M) baseplate offers additional mounting flexibility for coarse positioning of the translation stage within a setup. Three 1.26" long, 1/4" (M6) counterbored slots allow for coarse translation adjustment of the stage. The orthogonal dovetails on the top of the XRN-B1 allow the stage to be mounted in two orientations. The middle slot is designed to be secured by two 1/4"-20 (M6) cap screws onto an optical table or breadboard, which allows the stage to be aligned with the table's or breadboard's hole pattern.

Z-Axis Stage Configuration
For situations where only a Z-axis translation stage is needed, either the XRN-XZ or the XRN-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 XRN-XZ angle bracket (sold above) can be used for situations where the X-axis translation stage needs to be mounted vertically. The XRN-XZ angle bracket can be secured directly to the XRN-B1(/M) baseplate.

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 2" Wide Mating Dovetail Stages
  • Additional Dovetail Compatible with 34 mm Rail Accessories

These Extended Baseplates provide a convenient way to mount our XRN25 series translation stages on a breadboard or optical table. All 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 XRN25DR2, XRN25DR, and XRN25DR3 come in lengths of 150 mm, 250 mm, and 500 mm, respectively. For XRN25 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 XRN25-RC3 rail carriers sold above can be used to mark a specific location on the baseplate before moving the stage.

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

Rail Positioners Flanking an XRN Stage
Click to Enlarge

The XRNN Positioner and XRNN1 Return Positioner can provide fine alignment of translation stages mounted on an extended dovetail baseplate.
  • Clamps Directly to 2" 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
  • XRNN(/M) Positioner:
    • 1/4"-80 Adjuster Screw Provides 0.013" (320 µm) of Translation per Revolution
    • Translation Range of 0.4" (10.2 mm)
  • XRNN1(/M) Return Positioner:
    • Spring Loaded Plunger with Travel Range of 0.17" (4.3 mm)
    • Use with XRNN(/M) Positioner for Bidirectional Adjustment

The XRNN(/M) Translation Stage Positioner and XRNN1(/M) 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 2" wide mating dovetail that can be locked to the extended baseplate using a clamping mechanism (3/16" [5.0 mm] hex), providing quick and convenient placement along the rail.

The XRNN(/M) incorporates an F25SS100 1/4"-80 adjuster screw to provide smaller, smoother movement than coarse translation by hand. The screw allows for 0.4" (10.2 mm) of travel before the interior of the bushing is exposed; longer adjuster screws can be installed if desired.

The XRNN1(/M) translation stage return positioner is comprised of a spring-loaded plunger integrated into a 2" mating dovetail clamp. The plunger can travel a maximum range of 0.17" (4.3 mm), and the compression spring tension can also be adjusted with a 5/32" (4.0 mm) hex driver. When used in conjunction, the XRNN(/M) positioner and XRNN1(/M) 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 XRNN1(/M) return positioner, compressing the spring loaded plunger. Retracting the adjustment screw on the XRNN(/M) positioner causes the spring-loaded plunger on the XRNN1(/M) return positioner to expand, which keeps the carrier or stage in contact with the actuating screw of the XRNN(/M) 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.
