Thorlabs' 2-axis compact translation stages provide 25 mm of linear translation with less than 125 µrad of deviation per axis in pitch and yaw over the full range of travel. These stages use crossed-roller steel bearings to support precision motion. The monolithic top and bottom plates feature integrated micrometer mounts and are machined from cast tool and jig aluminum for high stability and minimal internal stress.
After each stage is manufactured, the pitch, yaw, and vertical straightness of the stage are tested. This ensures that each stage meets the stated specifications over the full translation range. A summary of the test results is provided on an individualized data sheet that ships with each stage. Click here for a sample LX20 data sheet.
The mounting surface includes an array of seven 1/4"-20 (M6) tapped holes with 1/2" (12.5 mm) spacings. Each stage axis is lockable via a side-located 5/64" (2.0 mm) hex screw in a locking bracket to guard against accidental movement. The stages can be bolted directly to the optical table using four counterbored 1/4" (M6) holes that are revealed by translating the middle plate. On the LX20(/M) stage, the micrometer attached to this plate partially blocks one of the mounting holes beneath it, so it may be necessary to first remove this micrometer depending on the screw and hex driver used. The base of the stage also has four Ø2.4 mm alignment holes for use with Ø3/32" dowel pins.
These stages come equipped with a metric micrometer head for each axis, graduated in millimeters, with 500 µm of travel per revolution. The micrometer can be translated using the knurled knob or, for finer control, a 5/64" (2.0 mm) hex key. The micrometer can be removed and replaced by loosening the side-located flexure clamp with a 5/64" (2.0 mm) hex key. This flexure clamp can hold any micrometer that has a Ø3/8" (Ø9.5 mm) mounting barrel.
Each stage is designed as a standalone stage with a specific number of axes; as such, single-axis stages cannot be combined into multi-axis stages and multi-axis stages cannot be disassembled into single-axis stages. We also offer single- and three-axis versions of these stages. For modular multi-axis stages, please see our quick-connect 25 mm travel stages and compact, quick-connect 25 mm travel stages.
Note: If removing the micrometer, ensure either that the locking bracket is fully tightened or that the spindle is fully retracted and no longer engaged with the moving body of the stage. Failure to do so could result in damage to the stage or require it to be recalibrated to meet its specified performance.

The upper micrometer must be removed to access one of the mounting holes in the base.
- 25 mm Translation in X and Y Axes
- 1.50" (38.0 mm) Deck Height
- 500 µm Translation per Micrometer Revolution
- Compact Monolithic Construction for Superior Performance
The LX20(/M) stage allows for 25 mm of travel along the X and Y axes. The stage comes with two 150-801ME-H micrometers. Please note that this stage is taller than the single-axis LX10(/M) stage by 0.52" (13 mm). Directly replacing one with the other might require realignment of other fixtures.
This stage can be bolted directly to the optical table using four counterbored 1/4" (M6) holes that are revealed by translating the middle plate. The micrometer attached to this plate blocks one of the mounting holes beneath it; to access this hole, the micrometer must first be removed, as illustrated in the photo to the right. The base of the stage also has four Ø2.4 mm alignment holes for use with Ø3/32" dowel pins.
Note: If removing the micrometer, ensure either that the locking bracket is fully tightened or that the spindle is fully retracted and no longer engaged with the moving body of the stage. Failure to do so could result in damage to the stage or require it to be recalibrated to meet its specified performance.
For more detailed information, please see the Specifications table above.
Zoom- 25 mm Translation in X and Z Axes
- 500 µm Translation per Micrometer Revolution
- Compact Monolithic Construction for Superior Performance
The LX20XZ(/M) stage allows for 25 mm of travel along the X and Z axes, where X-axis translation is parallel to the face of the Z-axis stage. The stage comes with two 150-801ME-H micrometers. Please note that this stage is shorter than the three-axis LX30(/M) stage by 0.51" (12.9 mm). Directly replacing one with the other might require realignment of other fixtures.
This stage can be bolted directly to the optical table using four counterbored 1/4" (M6) holes that are revealed by translating the middle plate. The base of the stage also has four Ø2.4 mm alignment holes for use with Ø3/32" dowel pins.
Note: If removing the micrometer, ensure either that the locking bracket is fully tightened or that the spindle is fully retracted and no longer engaged with the moving body of the stage. Failure to do so could result in damage to the stage or require it to be recalibrated to meet its specified performance.

Zoom- 25 mm Translation in Y and Z Axes
- 500 µm Translation per Micrometer Revolution
- Compact Monolithic Construction for Superior Performance
The LX20YZ(/M) stage allows for 25 mm of travel along the Y and Z axes, where Y-axis translation is perpendicular to the face of the Z-axis stage. The stage comes with two 150-801ME-H micrometers. Please note that this stage is shorter than the three-axis LX30(/M) stage by 0.51" (12.9 mm). Directly replacing one with the other might require realignment of other fixtures.
This stage can be bolted directly to the optical table using four counterbored 1/4" (M6) holes that are revealed by translating the middle plate. The base of the stage also has four Ø2.4 mm alignment holes for use with Ø3/32" dowel pins.
