Abstract: A method of measuring spherically mounted retroreflector (SMR) with a 3D coordinate measurement device such as a laser tracker. The SMR includes an open-air cube corner retroreflector having a vertex point located near a sphere center of the SMR. Measurements of the SMR to the vertex point are corrected to indicate 3D coordinates of the SMR sphere center by accounting for SMR depth error and SMR runout error.
