Abstract
A spherically mounted retroreflector (SMR) includes a substrate, an optic, and an adhesive. The substrate has a partially spherical outer surface and a cavity, the partially spherical outer surface has a sphere center. The optic has a cube-corner retroreflector fixedly disposed within the cavity; the cube-corner retroreflector has an optical vertex. The adhesive is disposed between the optic and the substrate and fixedly adheres the optic to the substrate. The optical vertex is coincident with the sphere center. The substrate is made from a ferromagnetic material and has an electroless nickel outer coating.
