100 mm Linear Translation Stage, Direct-Drive Servo Motor
Controller for the DDSM100(/M) Stage
Thorlabs' DDSM100 low-profile, direct-drive stage provides 100 mm of travel with 0.5 µm resolution and a maximum speed of 500 mm/s. The 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. A precision-grooved linear bearing provides 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 ±1.5 μm.
Adapter brackets are also available that allow optomechanical components to be mounted close to the linear travel of the stage in applications such as a delay line.
Please Note: Magnetic components should not be mounted to the stage platform. Magnets prevent proper homing and can affect the accuracy of the stage's encoder even after the magnetic component has been removed. When no power is applied, the platform of the stage has very little inertia and is virtually free running. This may make the stage unsuitable for applications where the stage's platform needs to remain in a set position when power is off.

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 DDSM100 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 KBD101 controller.
Please Note: Magnetic components should not be mounted to the stage platform. Magnets prevent proper homing and can affect the accuracy of the stage's encoder even after the magnetic component has been removed. These stages are not suitable for operation in a vertical (Z-axis) orientation. When no power is applied, the platform of the stage has very little inertia and is virtually free running. This may make the stage unsuitable for applications where the stage's platform needs to remain in a set position when power is off.
For 2-axis applications, two DDSM100 stages can be bolted together in an XY configuration using the DDSMP1 adapter plate as shown above in the Overview tab.
The DDSMA1 and DDSMA2 adapter plates attach to the end of the DDSM100 stage using the two supplied M3 x 20 screws (see image to the right) and allow optomechanical components to be mounted close to the linear travel of the stage in applications such as a delay line. The plates are drilled and tapped with six 1/4”-20 (M6) and five 8-32 (M4) holes.

KCH601 USB Controller Hub (Sold Separately) with Installed K-Cube and T-Cube™ Modules (T-Cubes shown on the KAP101 Adapter)
Thorlabs' KBD101 K-Cube™ Brushless DC Motor Controller provides local and computerized control of a single motor axis. It features a top-mounted control panel with a velocity wheel that supports four-speed bidirectional control with forward and reverse jogging as well as position presets. A backlit digital display is also included that can have the backlit dimmed or turned off using the the top-panel menu options. The front of the unit contains two bidirectional SMC trigger ports that can be used to read a 5 V external logic signal or output a 5 V logic signal to control external equipment. Each port can be independently configured.
Please note that this controller does not ship with a power supply. Compatible power supplies are listed below. Additional information can be found on the main KBD101 Brushless DC Servo Motor Controller page.

The KPS101 Power Supply Unit
The KPS101 power supply outputs +15 VDC at up to 2.4 A and can power a single K-Cube or T-Cube with a 3.5 mm jack. It plugs into a standard wall outlet.
The KCH301 and KCH601 USB Controller Hubs each consist of two parts: the hub, which can support up to three (KCH301) or six (KCH601) K-Cubes or T-Cubes, and a power supply that plugs into a standard wall outlet. The hub draws a maximum current of 10 A; please verify that the cubes being used do not require a total current of more than 10 A. In addition, the hub provides USB connectivity to any docked K-Cube or T-Cube through a single USB connection.
For more information on the USB Controller Hubs, see the full web presentation.
