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

The 9071 Four-Axis Tilt Aligner allows intuitive alignment of optical tubes or paths with an input and an output like electro-optic or acousto-optic modulators or lenses. Center one end to the laser beam, then adjust the other until the beam emerges. All motions are independent and connected to a single base, so you won’t induce coupled motion while making adjustments. These stages are great for aligning New Focus™ optical modulators.

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.
