Abstract: A spherical grid for use in instrumentation comprising a rigid non-magnetic frame (10) having a pattern of holes (16). Into each hole a flat wafer (20) is placed, each wafer having etched therein holes defining the grid mesh. The frame maintains the geometric conformal shape allowing large units to be constructed.
