1/4" Travel Translation Stage




  • Modular XYZ Configurable Translation Stages with Hardened Steel Guide Pins
  • Ball Bearing Design for Precision Motion and Long Life
  • Actuator Screw-or Micrometer-Driven Versions

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 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.

 


1/4" (6.4 mm) Travel Translation Stage

  • End-Mounted Adjustment Screw
  • Lockable
  • XYZ Configurable

 

The MS1 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.

Side-Actuated 1/4" (6.5 mm) Travel Translation Stage

  • Side-Mounted Micrometer
  • Lockable
  • XYZ Configurable

 

The MS1S 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.

MS Series Stage Plates

 

The MS101 base plate has a central 8-32 (M4) through hole and four precision machined dowel holes that allow for the MS1 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 to be vertically mounted so that the surface of the stage is orthogonal, within 2mrad, to the horizontal plane.

The MS103 adapter plate has a central #8 (M4) through hole to secure the plate to the MS1 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. 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.
