220 mm Linear Translation Stage, Direct-Drive Servo Motor
Our ODL220 Optical Delay Line Kit
Thorlabs' DDS220 low-profile, direct-drive translation stage provides 220 mm of travel with 50 nm resolution and a maximum speed of 300 mm/s. This stage is ideal for applications that require high speeds and high positioning accuracy, including automated alignment, surface inspection, mapping, and probing.
An innovative, low-profile design with integrated, brushless linear motors eliminates the external housings that create mechanical clash points and impede access to the moving platform. The direct-drive technology removes the need for a lead screw, eliminating backlash and internal flexible ducting ensures cables cannot become trapped as the mechanism moves. Twin, precision-grooved linear bearings provide superior rigidity and linearity with excellent on-axis accuracy. This backlash-free operation coupled with high-resolution, closed-loop optical feedback ensures a minimal bidirectional repeatability of ±0.25 μm. The DDS220 stage is at the core of our ODL220 Optical Delay Line kit.
Please note that these stages are not suitable for operation in a vertical (Z-axis) orientation.
Accessory Mounting Plates
The flying leads are terminated in a male 15-pin D-Type and male 8-pin round DIN connector. Pin details are given below.

Motorized Linear Translation Stages
Thorlabs' motorized linear translation stages are offered in a range of maximum travel distances, from a stage with 20 µm of piezo translation to our 600 mm direct drive stage. Many of these stages can be assembled 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 motorized translation stages. In addition to motorized linear translation stages, we offer motorized rotation stages, pitch and yaw platforms, and goniometers. We also offer manual translation stages.
These stages incorporate piezoelectric elements in a variety of drive mechanisms. Our Nanoflex™ translation stages use standard piezo chips along with manual actuators. Our LPS710E z-axis stage features a mechanically amplified piezo design and includes a matched controller. The PD1 stage incorporates a piezo inertia drive that uses "stick-slip" friction properties to obtain an extended travel range. The Elliptec™ stages use resonant piezo motors to push and pull the moving platform through resonant elliptical motion.
Stepper Motor Stages
These translation stages feature removable or integrated stepper motors and long travel ranges up to 300 mm. The MLJ150 stage also offers high load capacity vertical translation. The other stages can be assembled into multi-axis configurations.
DC Servo Motor Stages
Thorlabs offers linear translation stages with removable or integrated DC servo motors. These stages feature low profiles and can be assembled in multi-axis configurations.
Direct Drive Stages
These low-profile stages feature integrated brushless DC servo motors for high speed translation with zero backlash. When no power is applied, the platforms of these stages have very little inertia and are virtually free running. Hence these stages may not be suitable for applications where the stage's platform needs to remain in a set position when the power is off. We do not recommend mounting these stages vertically.
Characterized by high-speed translation and high-positional accuracy, the DDS220 stage is well-suited for surface mapping and characterization applications where there is a need to move a camera or probe at constant velocity while simultaneously capturing data. Very precise, fine positioning and control is easily achieved through a combination of the stable closed-loop control system and a BBD series controller with associated MJC001 joystick option (described below).
Depending on your application need, we recommend using our BBD series 1- or 2-Axis Brushless DC Servo Motor Controller. With a user-configurable, S-curve acceleration/deceleration profile that enables fast, smooth positioning without vibration or shock, these controllers are ideal for any motion control applications demanding operation at high speeds (hundreds of mm/s) and high encoder resolution. Incorporating the latest digital and analog techniques as well as high-bandwidth, high-power servo control circuitry, the BBD series controller is designed to drive any brushless DC servo motor products with continuous output currents of up to 5 A.
These DC servo controllers incorporate Thorlabs' standard APT control and programming interface, enabling easy integration into automated motion control applications. For greater flexibility, both a USB and RS232 computer interface is provided, and automated PC control of the stage is supported with the supplied software development kit (SDK). The fully documented SDK supports all major development languages running on Windows and comes in the form of ActiveX libraries or a conventional dynamic link library (DLL).
USB connectivity provides easy plug-and-play PC operation. Multiple units can be connected to a single PC via standard USB hub technology for multi-axis motion control applications. Combining this feature with the user-friendly APT software allows the user to program and carry out complex move sequences in a short space of time. For more information, please see the full Brushless DC Servo Motor Controller presentation.
The MJC001 joystick console has been designed to provide intuitive, tactile, manual positioning of a stage. The console features a two-axis joystick for XY control. In most applications, the default parameter settings saved within the controller allow the joystick to be used out-of-the-box, with no need for further setup, thereby eliminating the need to be connected to a host PC and allowing true remote operation. This joystick is compatible with our Benchtop Brushless Controllers, Rack-Mounted Brushless Controller, and Stepper Motor Controllers.
This mounting plate enables our MAX300 and MBT61x series of 3-axis stages to be mounted on the DDS220 stage.

Two accessory plates are offered for use with the DDS220 Direct Drive Stage featured above. The DDSA01(/M) Mounting Plate bolts to either end of the stage using two user-supplied 1/4"-20 (M6) bolts and allows accessories to be fixed at either end of travel.
