Thorlabs' Motorized Translation Stages provide electronically controlled linear motion along a well-defined axis. The MT1-Z8 (MT1/M-Z8) Single-Axis Stage provides 12 mm (0.47") of travel along one axis, while the MT3-Z8 (MT3/M-Z8) Three-Axis Stage provides travel in three dimensions. Each stage is equipped with a 1.00" x 1.00" (25.0 mm x 25.0 mm) tapped hole matrix that includes seven 1/4"-20 (M6) taps for compatibility with standard optomechanics.

The moving platform contains holes for alignment pins that ensure orthogonality when the stage is stacked with other stages or connected to our accessories. Horizontal loads of 20 lbs (9 kg) and vertical loads of 10 lbs (4.5 kg) are supported by the actuator's inline 67:1 planetary gear head. The stages feature hardened steel linear bearings for precision motion and long life.

Mounting Adapters and Stage Combinations
Thorlabs' adapter plates and brackets provide a convenient way to mount the MT1-Z8 on an optical table or breadboard; to allow several stages to be combined in XY, XZ, or XYZ configurations; and to reduce the overall length of the stage by repositioning the stage's actuator. Photos of these adapters in use are shown below.

Included and Compatible Actuators
The included Z812B DC servo actuator features a 500 mm (1.64 ft) cable length, an internal limit switch to prevent travel outside of the intended range, and an encoder that provides 29 nm resolution (see the Specs tab for additional details). This actuator attaches to the stage using a flexure clamp that tightens around the Ø3/8" barrel. If desired, the Z812B actuator can be replaced by any manual or motorized 12 mm (0.47") actuator that includes a Ø3/8" barrel, including stepper motor actuators and manual micrometers.

Controller Options
For low-power stages such as the MT1-Z8 (MT1/M-Z8), Thorlabs recommends the TDC001 T-Cube Motor Controller and TPS001 Power Supply. Each TDC001 provides control for a single axis, with or without a PC. It is bundled with Thorlabs' apt™ software, which supplies out-of-the-box stage control from a PC and enables support for common programming interfaces like LabVIEW, LabWindows, and ActiveX. A USB cable is included with the TDC001.

12 mm (0.47") Motorized Translation Stages

  • Single-Axis and Three-Axis Versions
  • Z812B DC Servo Actuator Provides 12 mm (0.47") Travel per Axis
  • Includes Two Alignment Pins per Axis for Stage Stacking and Mounting Accessories
  • Controller and Power Supply Sold Separately


Thorlabs' MT1-Z8 (MT1/M-Z8) Single-Axis and MT3-Z8 (MT3/M-Z8) Three-Axis Motorized Translation Stages provide linear, orthogonal motion in one or three dimensions. Seven 1/4"-20 (M6) tapped holes allow easy integration with a wide variety of common optomechanical setups. The stages feature hardened steel linear bearings for precision motion and long life.


The MT1-Z8 stage is designed for single-axis translation. For applications requiring XY motion, simply purchase two MT1-Z8 stages and stack them using the provided alignment pins to ensure orthogonality. If XYZ motion is desired, then we recommend the MT3-Z8 stage. In addition to alignment pins for all three axes, the MT3-Z8 includes an MT401 Base Plate and an MT402(/M) Right-Angle Bracket. For more details on these accessories, please read below.


Each axis requires a standalone controller unit and power supply to operate. For this purpose, we recommend our TDC001 T-Cube Motor Controller and TPS001 Power Supply, which are described in more detail below.

The motor cable that is built into the Z812B actuator is 0.5 m (1.64 ft) long. If more length is required for your application, we recommend our PAA632 Extension Cable, which provides an additional 2.5 m (8.20 ft).

Base Plate for Breadboards and Optical Tables

  • Mount an MT1-Z8 Single-Axis Stage to a Breadboard or Optical Table
  • Contains Four 1/4" (M6) Counterbored Slots for Imperial and Metric Compatibility
  • Alignment Holes Ensure Parallelism


Although the MT1-Z8 (MT1/M-Z8) Single-Axis Stage sold above can be directly mounted to a breadboard or optical table, mounting requires unobstructed access to the two bores in the middle of the moving platform. The MT401 Base Plate allows an attached stage to be positioned on a breadboard without having to disassemble a setup that already exists on the moving platform. Thus, it is particularly useful for XY, XZ, or XYZ multi-axis configurations. This base plate is included with the purchase of an MT3-Z8 (MT3/M-Z8) Three-Axis Stage.


The bottom of the translation stage is connected to the base plate using two 1/4"-20 (M6) cap screws. The two alignment pins included with the MT1-Z8 stage fit simultaneously into the stage and base plate, ensuring that the translation axis is parallel to the plate.

Right-Angle Bracket

  • Vertically Mount an MT1-Z8 Translation Stage
  • Designed for XY, XZ, or XYZ Configurations
  • Alignment Holes Ensure Orthogonality
  • Includes All Necessary Mounting Hardware for Imperial and Metric Setups


The MT402 Right-Angle Bracket orients an MT1-Z8 (MT1/M-Z8) Single-Axis Stage in the vertical plane and allows for the construction of XY, XZ, or XYZ arrangements. This bracket is included with the purchase of an MT3-Z8 (MT3/M-Z8) Three-Axis Stage.

To begin the assembly process, insert the two alignment pins provided with the PT1-Z8 stage into the stage's alignment holes. Then position the bracket's alignment holes above the pins. The bracket can be fastened down using two 1/4"-20 (M6) cap screws. At this point, the bracket's vertical mounting surface will accommodate a stage that is attached horizontally (for XY configurations) or vertically (for XZ or XYZ configurations).

Side-Mounted Actuator Adapter

  • Reduce the Total Length of the MT1-Z8 Stage
  • Four 4-40 Mounting Screws Included

The MT405 Side-Mounted Actuator Adapter allows the actuator to be repositioned from the rear of the stage to the side, as shown in the image on the right. The adapter attaches to the side of the stage that does not contain the locking screw and plate. This reduces the overall length of the stage assembly by 1.2" (30 mm), while increasing the width by 0.71" (18 mm).

Adapter Plate for Flexure Stage Accessories

  • Use Flexure Stage Accessories with an MT1-Z8 Stage
  • Includes Two Alignment Pins that Ensure Parallelism
  • Two 1/4"-20 Cap Screws Provided

The MT406(/M) Flexure Stage Accessories Adapter Plate is compatible with our full range of flexure stage accessories and is ideal for creating basic fiber coupling solutions. It fastens directly to the top of the MT1-Z8 (MT1/M-Z8) stage with two 1/4"-20 (M6) cap screws and contains twenty-eight 6-32 (M3) taps.

T-Cube Motor Controller

  • Provides a Front Panel for Controlling Motorized Stages or Actuators (See Table at Right)
  • Interfaces with Computer using Included USB 2.0 Cable
  • Compact Footprint: 2.4" x 2.4" x 1.8" (60 mm x 60 mm x 47 mm)
  • Power Supply Not Included

The TDC001 T-Cube Motor Controller provides local and computerized control of a single motor axis. It features a top-mounted control panel with move/jog buttons that move the actuator in discrete steps and a velocity potentiometer that moves the actuator at various speeds. Thorlabs' apt™ Control Software is included.

T-Cube Power Supplies

The preferred power supply (i.e., single channel, multi-channel, or hub-based) for your TDC001 Motor Controller depends upon your application and whether you already own a T-Cube or a compatible power supply.

The TPS001 Power Adapter supports a single T-Cube controller, while the TPS008 Power Adapter supports up to eight T-Cubes simultaneously. These two options power each T-Cube using a separate cable. In contrast, the TCH002 USB Controller Hub supports up to six T-Cubes simultaneously. Each connected T-Cube receives power from the hub and shares a single USB connection to the control PC.

Motor Extension Cable

The PAA632 Extension Cable provides an additional 2.5 m (8.20 ft) of cable length for the 15-pin D-type connectors used throughout our motorized actuator selection. The male end connects to the controller, while the female end connects to the motor.
