Device Alignment Stage, Compact, Six-Axis, 2 mm Linear, 4 degree Angular, 4-40

The 9031 Six-Axis Device Alignment Stage is ideally suited for intuitive alignment of electro-optic, acousto-optic modulators or lenses. The stage features a removable, 4-40 (M3) threaded top plate to simplify mounting and replacement of optical devices. A top plate is included with the mount but they are also sold individually. Two keying pin holes in the base assist in setting the exact mounting location of the stage in industrial applications. The mounting slots on the 9031 for 8-32 (M4) cap screws are compatible with industry standard mounting hole spacing. This means they can be mounted on to our standard tables and breadboards with nothing more than our 8-32 to ¼-20 (M4 to M6) TR-series thread adapters and screws.

Kinematic Device Alignment Stages combine the capabilities of multiple, stacked translation stages into a single stage with multiple actuators. These stages are designed to align a device or optic, such an acousto-optic modulator, to a beam path, avoiding the added wobble of combining components for multi-axis positioning. These stages have all degrees of freedom needed to align one optical axis to another. The five-axis stages provide additional control of the focus and the six-axis stage provides roll. Each degree of freedom has one actuator for motion, such that two actuators provide translation when moved equal amounts, while one actuator's motion provides the tilt about the bisecting axis. Rotations of the mounting plate around its center, then, arise from turning two actuator screws in opposite directions.

Our multi-axis stages are designed for applications where precise positioning and high stability are required. Shown here is a typical application of aligning an optical modulator to a laser beam with our four-axis device alignment stage.
