Goniometer Stages

It is the same machine. A goniometer stage swings through an arc about a rotation centre that sits above its own table, so the part tilts about a point you choose rather than about the stage. That is what separates it from a rotary stage, which turns about its own axis, and from a tilt platform that pivots at its base.

It is the distance from the mounting surface to the point the motion turns about — published for every model on this site, for example 50 ± 0.2 mm. Put the feature you are aligning at that height and it tilts in place; put it elsewhere and every tilt also translates it, which is usually the thing you were trying to avoid.

That is the normal way to build two-axis tilt, and the series is supplied in 60 mm and 80 mm frames to make the pairing straightforward. Confirm the mounting pattern, the combined height and the payload of the lower axis in the quotation — the lower stage carries the upper stage as well as your part.

A limited arc, published per model as a total with the half range shown beside it. These are alignment stages, not indexing tables: if you need continuous rotation, the rotary stage series covers 360° models.
