The Model 8071 Four-Axis Tilt Aligner offers XYΘxΘy Picomotor adjustment and allows intuitive alignment of optical tubes or paths with an input and an output such as electro-optic or acousto-optic modulators or lenses. All motions are independent and connected to a single base, so you won’t induce coupled motion while making adjustments. This XYΘxΘy Picomotor Aligner is ideal for positioning modulators or isolators and for coupling light into waveguide devices. It is offered with English or metric tapped holes.

The Model 8095 six-axis aligner offers XYZΘxΘyΘz Picomotor adjustment making it ideal for semiconductor-wafer alignment. It is offered with English or metric 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 as 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.
