The 9082-V Vacuum Wide Five-Axis Aligner is similar to the 9081, but with a wider removable platform for mounting larger components. With this stage, aligning a laser beam through a tube is simple. Turning both X screws or both Y screws equal amounts in opposite directions gives you tilt or pivot about the center of the plate. Turning them in the same direction gives you pure translation. Z adjustment allows precise translation along the optic axis. The 9082-V has (7) 1/4-20 tapped holes and (2) 8-32 tapped holes.
Multi-axis Optic Positioning in a Compact Unit
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.
