Device Alignment Stage, Five-Axis, 3 mm Linear, 8° Angular, M4 and M6

The 9081 Five-Axis Aligner adds Z adjustment to the single-component alignment stage, allowing the same precise translation along the optical axis. This model also features a removable mounting platform. The 9081 has both 1/4-20 and 8-32 tapped holes in its surface for mounting devices and optics. The 9082 Wide Five-Axis Aligner is similar to the 9081, featuring a wider removable platform with a larger (22 N) load capacity for mounting larger components.
The 9082 has the same 1/4-20 tapped holes and 8-32 tapped holes. Models 9081-M and 9082-M are metric versions of these stages with M4 and M6 tapped holes.

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.
