Abstract
We briefly describe a spectrograph concept designed for both high wavelength and high spatial resolution (in one dimension) of magnetospheric far and extreme ultraviolet (FUV and EUV) emission. We refer to the design as a Single Element Imaging Spectrograph (SEIS). It is a single bounce diffractive system which combines the spectral properties of a Rowland mount spectrograph with the imaging (spatial resolution) properties of a Wadsworth through the use of a toroidal diffraction grating. No primary optics are necessary making the system especially attractive for use in the EUV and FUV where low reflectivity of common optical coatings can severely limit instrument sensitivity.
