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 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 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.

Accessories
Additional functionality is provided by a complete line of accessories that include multi-axis assembly kits, a position encoder, rail carriers, rotation adapter, rails, stage positioners, and micrometer conversion kits. Other than the position encoder, 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 our quick-connect construction components, see the Quick-Connect Stages tab.

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.
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.

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.

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 Z axis is upside down in all your picture. Can it be mounted rotated for load bearing? In other words, the micrometer is holding the weight, not the spring?
cdolbashian  (posted 2023-06-23 01:02:51.0)
Thank you for reaching out to us with this inquiry! Within the overview tab, we actually spec the maximum vertical load in terms of the actuator (noting the footnote). When oriented such that the actuator is supporting the vertical load, the max limit is 4kg.

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.

Quick-Connect Translation Stages, 25 mm Travel


Click to Enlarge

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 x 1.0) 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" 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" 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.

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.

Stage Position Encoder

ENCXR25 Encoder Kit Specifications
On-Axis Accuracy 5.0 µm (Typ.)
Repeatability 2.0 µm (Typ.)
Resolution 1.0 µm
Power/Data Cable (Included) 1 m USB Cable,
Type A to Micro-B
Power Supply (Sold Separately) DS5
  • Optical Position Encoder Mounts to XR25 Series Stages
  • Local Manual Control and Position Readout via Onboard Display
  • Remote Control via USB and Kinesis Software
  • Includes 1 m USB Cable (DS5 Power Supply Sold Separately)

The ENCXR25 Stage Position Encoder is designed for our XR25 series translation stages and provides positional information in either inches or millimeters to a resolution of 1.0 µm and an accuracy of 5.0 µm. The module is comprised of the optical encoder scale bracket that attaches directly to the stage and the position reader assembly which is then attached to the bracket, as illustrated in the animation below. The module is powered via a USB mini-B connection. A 1 m long USB type A to micro-B cable is included in the kit, but the DS5 power supply is sold separately. In addition to power, the USB connection also enables the encoder module to display the stage position and control the unit via our Kinesis software. We also offer the ENCXR50 position encoder for XR50 series stages.

The encoder must be installed on the same side of the stage where the lock plate is initially installed, the left side when looking at the end of the stage with the dovetail clamping screw, as illustrated in the video and photo below. The lock plate must first be removed and the micrometer must be mounted either on the other side or on the end.

Mounting Adapters

  • 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.

Base Plate 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" 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.
