Abstract
An apparatus includes a source configured to generate a beam of electromagnetic radiation propagating in a first direction and a spatial filter. The spatial filter is configured to restrict the beam of electromagnetic radiation in one or more dimensions and includes at least one set of rods including a first rod and a second rod. The first rod is a first cylindrical structure with a first axis in a first plane and the second rod is a second cylindrical structure with a second axis in a second plane parallel to the first plane. The first axis and the second axis are longitudinal axes, and the first and the second rods have shaped surfaces in portions of their respective surfaces facing one another.
