Abstract
We introduce a novel application of reflective axicon surfaces to high performance image-forming objectives. The reflective surfaces are arranged such that the optical and mechanical axes are collinear, yet have the potential to provide unobscured transmission. Offering the ability to compete with the performance of traditional diffraction-limited unobscured optical systems provides a design and fabrication alternative where demanding optical requirements must be met. There are four possible arrangements for construction, with the two outer reflectors always being concave and the two inner reflectors being either concave or convex. Multitudes of novel design forms are explored. We describe monolithic and two-piece solid, two- and three-piece reflective, and two-piece hollow-solid hybrids. We analyze the performance of such designs and compare to the performance of both refractive and reflective systems.
