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" 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" 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).

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.

• Photos show a mix of side- and end-mounted micrometers, however, the product lists include stages with all side-mounted or all end-mounted micrometer options. Please note that all configurations except for XY require assembly kits; these kits are included in every applicable product list.
• Take care during assembly to ensure no collisions occur with the Z-axis stage during full downward extension.
• Available as a preassembled kit below.

XRN25P-K2 Stage Kit Preassembled in XYZ Configuration

• Conveniently Preassembled XRN25P Stages in XY or XYZ Configurations
• Side-Mounted Micrometers Suitable for Adjustment in Tight Spaces
• Included Dovetail Clamp Screw has a Maximum Torque of 15 in•lbs

Thorlabs offers XRN25P(/M) stages preassembled in XY and XYZ configurations. The XRN25P-K1(/M) Preassembled XY Stage consists of two XRN25P(/M) stages preassembled in an XY configuration. The XRN25P-K2(/M) Preassembled XYZ Stage consists of three XRN25P(/M) stages preassembled in an XYZ configuration using an XRN-XZ(/M) Assembly Kit. The XRN25P-K2 eliminates the need to buy and manually assemble the multi-axis stage assembly kits, which are sold below.

Each stage features a side-mounted metric micrometer for 25 mm of travel at 500 µm translation per revolution. The XRN25P offers 1/4"-20 tapped mounting holes, while the XRN25P/M offers M6-tapped mounting holes. The micrometer can be moved to the opposite side of the stage by swapping the micrometer mounting blocks with the steel locking plate. For more information, please see the Micrometer Conversion tab above. Micrometer conversion kits are available below that can be used to convert an end- or side-mounted stage into a side- or end-mounted stage, respectively.

• Kits Consist of Angle Bracket and Z-Axis Mounting Plate
• Supports X, Z, XZ, YZ, or XYZ Configurations
• 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.

• 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.

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.
