Brass 1&2-Axis Goniometers

Brass 1&2-Axis Goniometers

Our traditional brass goniometers are available in 15-, 25-, 40-, 60- and 65-mm square platform sizes. The brass material ensures exceptionally smooth low friction movement. They are available with either dovetail bearings or with v-groove bearings for inverted use. The drive screw incorporates a high-tolerance worm-gear mechanism which yields angular position readable to less than 12 arc minutes using the Vernier scale. As with all goniometers, the axis of rotation is situated parallel to and above the mounting platform. OptoSigma goniometers of like-size are designed to be stacked so that they have intersecting orthogonal axes of rotation. In this configuration, they have capability for orbit-like positioning about a single point. The GOH series of goniometers are lockable and finished in a flawless RoHS-compliant super black chrome.
