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 providse 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. Controller Options
The recommended controller for the DDSM100 direct-drive, linear translation stage is the TBD001 T-Cube Brushless DC Motor Controller. This controller provides a user-configurable, S-curve acceleration/deceleration profile that enables fast, smooth positioning without vibration or shock. See below for a brief overview, or click here to view the full presentation for these Brushless DC Motor Controllers. Dual-Axis Configuration
For dual-axis applications, two stages can be bolted together in an XY configuration by using the DDSMP1 XY adapter plate as shown to the left. Note that these stages are not suitable for operation in a vertical (Z-axis) orientation. Please contact Tech Support for more details. 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 see below for more details. Please Note: 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.
