1. A method of fabricating a mirror for use in limited rotation motor systems, said method comprising the steps of providing a mirror structure including at least one wall section, wherein said mirror substrate includes a beryllium mirror structure, and wherein said method includes the step of drawing the beryllium mirror structure from a fluid etching agent at a controlled rate such that the at least one wall section forms a tapered wall.
