New Focus Newport 9071 Four-Axis Tilt Aligner Stage 3mm Linear 8° Angular 8-32

The New Focus Newport 9071 is a four-axis device alignment stage designed to position and align optical tubes with both an input and an output port — such as electro-optic modulators, acousto-optic modulators, and precision lens assemblies. It provides 3 mm of linear travel and ±8° of angular adjustment across four independent axes, all connected to a single base so each motion remains fully decoupled from the others. Adjustments are made via the four front-mounted knobs, allowing an operator to center one end of the optical tube to a laser beam and fine-tune the exit alignment without inducing unwanted motion in the other axes.

Applications

The 9071 is used in photonics and optical research labs to align fiber-coupled or free-space components that require simultaneous control of position and angle — most commonly electro-optic (EO) and acousto-optic (AO) modulators, precision collimators, and beam-shaping lens tubes. It is especially well suited to New Focus modulator products, which it was specifically designed to mate with. In a typical setup, one end of the modulator is positioned to intersect the input beam, then the angular axes are adjusted to steer the output to the target port without disturbing the input alignment. The independent-axis design makes this iterative process significantly faster than stages with mechanically coupled motions. The 9071 remains a standard fixture on optical breadboards in ultrafast laser, spectroscopy, and fiber optics labs.
