A metrology mount system for large spaceborne optical systems is presented, whose verification testing has demonstrated this ability to simulate a zero-g environment within an uncertainty band of lambda/300 rms for the case of a mirror whose characteristic gravity deformation is 12(lambda). Assessments and/or compensations are obtained, for the effects of stiffness and mass nonuniformity due to faceplate thickness variations and calibration uncertainties in each of the support points of the sandwich structure mirror, by means of a detailed finite element model. Attention is also given to the optimization of forces to yield a minimum rms figure error, and to the method and results of the faceplate thickness mapping which determines spatial weight and stiffness variations. Interferometrically measured figure changes due to discrete changes in the applied force field are compared.
