1. A deformable mirror, comprising:
a mirror assembly comprising (i) a reflective face sheet having a reflective surface on a front side of the reflective face sheet and (ii) one or more ferrous materials selectively positioned within the mirror assembly, wherein the reflective face sheet has a non-uniform thickness between the front side of the reflective face sheet and a back side of the reflective face sheet opposite the front side; and
one or more electromagnets configured to generate a magnetic field that acts on the one or more ferrous materials to deform the reflective face sheet.
