1-Axis, Steel EXC™ Precision-Bearing Micrometer Goniometers

Opto Sigma's GOHT-S Goniometers are an absolute marvel of translation stage engineering. They are the first and only goniometer to feature curved EXC™ precision bearing ways that are processed directly into the body and base, resulting in the highest stiffness, load capacity and smoothness of any stage on the market. This patented bearing technology also provides the GOHT with low-friction, high-resolution movement as well as rotation axis displacement that is 1/10th the magnitude of dovetail bearing goniometers. 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 to have intersecting orthogonal axes of rotation. In this configuration, they have capability for orbit-like positioning about a single point. This family of GOHT stages are micrometer driven for recordable movements and include a carriage lock. All are made entirely from hardened tool steel and are plated with an RoHS-Compliant black chrome.
