A method of constructing an ion mirror having an axial axis which includes arranging electrode plate elements in parallel alignment along the axial axis and attaching a rigid structure to all of the electrode plate elements with adhesive, thereby fixing the electrode plate elements in their respective axial positions and parallel alignment. In an embodiment of the method, the electrode plate elements are arranged in parallel alignment by turning the electrode plate elements from a single workpiece. In an alternative embodiment, the electron plate elements are arranged in parallel alignment by stacking the electrode plate elements using precisely dimensioned spacers, and the spacers are then removed after attachment of the rigid structure.
