A collimator grid and a method of fabricating the collimator grid are disclosed. The method includes molding a plurality of plates, each plate includes a plurality of grooves in a first surface, a plurality of fin tips in a second surface disposed opposite to the first surface, plurality of ribs on a first pair of peripheral sides, a plurality of first fiducials formed on the plurality of ribs, and a plurality of second fiducials formed on a second pair of peripheral sides. The method includes machining the second surface to form the plurality of fins having predefined dimensions. Further, the method includes stacking the plurality of plates overlapping each other based on the plurality of first fiducials, and machining the plurality of ribs and first fiducials to form the collimator grid.
