1.1 Introduction
The Thorlabs’ DDSM100 low-profile, direct-drive stage provides 100 mm of travel with
500 nm 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. 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. Along with the Thorlabs KBD101 controller and the Thorlabs
software interface, it forms a truely plug and play system.
The DDSM100 stage has been designed for easy XY configuration when used with
the DDSMP1 XY adapter plate. Two KBD101 controllers are then required to control
two stages simultaneously in the XY configuration.
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.
