Dual-axis goniometer GCM-G

A goniometer stage is a device used to rotate an object precisely, within a small angular range, about a fixed point in space. Goniometers are similar to linear stages, but, rather than providing linear movement, the stage partially rotates about a fixed point above the mounting surface of the stage. In our product lines, the distance from the point of rotation to the mounting surface was designed so that two different goniometer models (GCM-G40M and GCM-65M) may be stacked in an XY configuration and both stages will rotate about the same point. The GCM-G Goniometer Stages employ precision micrometer as the actuation component, grinding dovetail bearing as the guide way. The precision dovetail design, accompanied by a backlash-free lead screw and a vernier scale, provides accurate and repeatable positioning. The side features 1° graduation lines and vernier scales with 0.1° resolution. ▲ Pure Rotational Motion About a Virtual Point ▲ 1° Graduation Marking on Side ▲ Backlash-Free Spring-Loaded Design ▲ Lockable Design
