摘要：
A spherical grid for use in instrumentation comprising a rigid non-magnetic frame having a pattern of holes. Into each hole a flat wafer 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.
