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.

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.
