1/4" Travel Translation Stage
Single-Axis Stage with
Stage Base Plate
Thorlabs offers two designs for 1/4" travel translation stages. The MS1 single-axis stage is actuated by an end-mounted 0.25 mm pitch thumbscrew. This stage is also the basis for our three-axis MS3 translation stage. The MS1S single-axis stage is actuated by a side-mounted micrometer. Since the MS1S removes the actuator from the translation axis, the MS1S is suitable for situations where it is necessary to mount the stage in close proximity to other components.
The modular design of these translation stage allows the user to quickly and precisely create multi-axis stage configurations using multiple MS1 or MS1S stages and stage plates. Each MS1 or MS1S stage has precision machined dowel holes in its top and bottom surfaces that allow two MS1 or MS1S stages to be connected together orthogonally within 2 mrad when the dowel pins are used. The MS series plates also have precision machined dowel holes. Each stage also features a side-located mounting plate that allows the stage to be locked in position using a 0.05" (1.3 mm) hex key.

Thorlabs' Smart Pack Initiative is aimed at minimizing waste while providing adequate protection for our products. By eliminating any unnecessary packaging, implementing design changes, and utilizing eco-friendly materials, this initiative seeks to reduce the environmental impact of our product packaging.
The updated MS3(/M) packaging primarily consists of recycled paper and cardboard and weighs 8.22% less than the original packaging. This weight change results in a 0.55 kg reduction in travel-based CO2 emissions per year, based on typical product sales.
As we move through our product line, we will indicate re-engineered, eco-friendly packaging with our Smart Pack logo, which can be seen above.
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 bearings 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 aluminum.
Ball Bearing Stages
These translation stages feature hardened steel linear bearings for precise motion and long life. They are available with a variety of actuators and in single-axis or preassembled multi-axis configurations.
These compact stages incorporate dovetails and a leadscrew for the translation mechanism. They are suitable in general purpose motion control applications.
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.
We offer vertical translation stages with crossed roller bearings for precise motion as well as long travel vertical stages for heavy-duty applications.

The MS1/M can be identified by the small dimple under the center tap on the underside of the stage.
The MS1(/M) series translation stage provides one axis of translation, and features an end-mounted adjustment screw. Components may be mounted to the top of the translation stage via five 8-32 (M4) tapped holes. The stage can be secured to the MS101 base plate or a Ø1/2" post using the 8-32 (M4) threaded hole located on the underside of the translation stage. Alternatively, there are two through holes accessible from the top of the stage that can be used to attach one MS1 translation stage to another MS1 translation stage. Two alignment dowels are provided with each stage; the dowels are used to precisely align two MS1 stages in an XY configuration or align the stage to the mounting plates available below.
The MS3(/M) is a 3-axis translation stage that comes completely assembled. The MS3 is built from three MS1 translation stages, one MS101 base plate, one MS102 right angle plate, and one adapter plate. The imperial version of the adapter plate includes four 6-32 and four 8-32 mounting holes for mounting various components; the metric version includes eight M4 mounting holes. Both the imperial and metric versions also include a 4 mm keyway lined with 4-40 (M3) tapped mounting holes to secure the optic mounts below to the stage.
The MS1S(/M) translation stage provides one axis of translation and features a side-mounted micrometer. Since the MS1S removes the actuator from the translation axis, the MS1S is suitable for situations where it is necessary to mount the stage in close proximity to other components. The MS1S stage is actuated with the 148-206ST (1/4" travel micrometer), while the MS1S/M is actuated with the 148-205ST (6.5 mm travel micrometer).
Components may be mounted to the top of the translation stage via five 8-32 (M4) tapped holes. The stage can be secured to the MS101 base plate or a Ø1/2" post using the 8-32 (M4) threaded hole located on the underside of the translation stage. Alternatively, there are two through holes accessible from the top of the stage that can be used to attach one MS1S translation stage to another MS1S translation stage. Two dowel pins are provided with each stage; the dowel pins are used to precisely align two MS1S stages in an XY configuration or align the stage to the mounting plates available below.

The MS103/M is marked as a metric component by a small dimple located next to the center tap.
The MS101 base plate has a central 8-32 (M4) through hole and four precision machined dowel holes that allow for the MS1(/M) translation stage to be secured in two orthogonal orientations when the dowels are being used.
The MS102 right angle plate has a central #8 (M4) through hole and four precision machined dowel holes on each of its two mounting surfaces. The MS102, with the use of the dowels, allows an MS1(/M) to be vertically mounted so that the surface of the stage is orthogonal, within 2 mrad, to the horizontal plane. Two hardened steel alignment dowel pins are provided with each bracket.
The MS103(/M) adapter plate has a central #8 (M4) through hole to secure the plate to the MS1(/M) translation stage. The four precision machined dowel holes on the underside of the plate allow the MS103 adapter to be mounted so that the key way on the top surface is either orthogonal or parallel, within 2 mrad, to the direction of the translation if the dowel pins are used. Two hardened steel alignment dowel pins are included with MS103(/M). The CT series of mounts are designed to fit into the keyway on the MS103 adapter plate, thus ensuring the orientation of the mounted component. The metric version can be identified by a small dimple on the underside of the plate located next to the central bore, shown in the photo to the right.
The CT101 has an internal SM1 threading for mounting Ø1" components or externally threaded SM1 components, which includes the SM1 lens tubes.
