Vacuum kinematic device alignment stages increase the utility of our popular device alignment stages by motorizing each of the axes. The addition of Picomotor™ actuators to each stage allows remote high-resolution (<30 nm) adjustment of various combinations of X, Y, Z, Θx, and Θy.
The 8081-UHV five-axis device aligners offer XYZΘxΘy Picomotor adjustment making them ideal for positioning optical modulators or isolators and for coupling light into waveguide devices. They are offered with 1/4-20 or M6 threaded mounting 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.
