摘要

We present the design of a novel anamorphic integral field spectrometer for diffuse ultraviolet astronomy. The system is designed to be able to measure emissions from faint diffuse astrophysical sources across a large field with good spectral resolving power. The design uses a standard focal plane image slicer and an anamorphic relay mirror and spectrometer to achieve an exceptional area, field of view, resolving power (A Omega R) product, the key figure of merit for a spectroscopic system intended to study line emission from extended or diffuse sources. We present a typical design with R similar to 1000 and an effective etendue (A Omega) of 1.5 x 10(-4) cm(2) sr.
