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.

The top and bottom of each stage feature quick connect dovetails (as shown in the image below) 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 built 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, 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. For more information about our quick-connect construction components, please see the Quick-Connect Stages tab.

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.
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.

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.

I only have an earlier version of solidworks - would it be possible for you to share a solidworks model of XRN25P-K2 that is compatible with SW2017?

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.

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 bearing 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 cast tool and jig aluminum. We also offer several vertical crossed-roller bearing stages (see below).

Flexure Stages

Thorlabs' 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.

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).

  • Compatible with 2" 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) base plate (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 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 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.

Mounting Adapters

  • XRN-A1 Adapter Enables Perpendicular Mounting of 2" Dovetail Components onto 3" Dovetail Components
  • XRN-A2 Adapter Enables Parallel Mounting of 2" Dovetail Components onto 3" 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" 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.

Stage Base Plate

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" Mating Dovetail Stages

The XRN-B1(/M) base plate offers additional mounting flexibility for coarse positioning of a 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 base plate.

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) base plate.
