title: Interferometer-grating spectrograph for high resolution astronomical spectroscopy in the middle uv.
abstract: A high resolution spectrograph is described, which is to be used for a program of uv astronomical spectroscopy from a moderately stabilized, star pointing balloon-borne platform. A spectral resolving power >10(5) is achieved using an optically contacted Fabry-Perot interferometer in crossed dispersion with a grating order sorter.
