Abstract

A new solution to the holographic grating equations designed for use in high resolution FUV applications is presented. The solution is shown through ray tracing to provide a sizable resolution enhancement over conventional Rowland circle grating solutions through the minimization of various aberration terms, especially astigmatism. This new design promises to also provide diffraction limited performance across a very large wavelength range.
