Abstract

Some embodiments of the invention include a coordinate measuring device, in particular a laser tracker, for capturing the position and alignment of a measuring aid, which is movable in space and comprises a retroreflector. In some embodiments, the coordinate measuring device may include at least a support fastened on a base so it is rotatable about a first axis of rotation; a beam deflection unit fastened on the support so it is rotatable about a second axis of rotation, which is essentially orthogonal to the first axis of rotation, a first bearing for the rotatable mounting of the beam deflection unit on the support, and a second bearing for the rotatable mounting of the support on the base.
