1-Axis, Large Platform, Ball Bearing Aluminium Goniometers

Opto Sigma's GOTHA-A Goniometers are large platform all-aluminum stages with exceptionally high rotation-axis heights, the largest being 228 mm (almost 9 inches high). They are driven by a high-tolerance worm-gear mechanism which, along with its high precision ball-bearing guides, yields angular position readable to 1 arc minute using the vernier scale. As with all goniometers, the axis of rotation is situated parallel to and above the mounting platform but they are also 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 GOTHA series of goniometers are lockable and finished in a RoHS-compliant black anodize.
