A novel design for a biaxial goniometric stage is described. The two stacked mutually perpendicular arc sections of the conventional eucentric goniometer head are replaced by a single tilt platform. The principal feature is the motion of a spheroidal cap in a matching socket, permitting two‐dimensional tilting action about a fixed center of rotation. This design has the advantage of a significant decrease in overall height of the goniometer head, providing additional space for a variety of attachments.
