SMR Target Holders

SMR (Spherically Mounted Retroreflector) target holders, often called nests or sphere mounts, are precision-machined accessories that securely hold a laser tracker's target sphere. They ensure that the target’s center point remains at a fixed, known offset from the surface or feature being measured, typically with tolerances of $\pm$0.0005" (0.013 mm)
