Newport MKS Device Alignment Stage, Four-Axis, Vacuum, 3 mm, 8°, M4 and M6 9071-V-M

The 9071-V-M Vacuum Compatible Four-Axis Tilt Aligner allows you to intuitively align optical tubes that comprise an input and an output (e. g., 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® modulators. M4 and M6 Threads. 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. Patent Number 5,303,035
