Galmatheia is a proposed far-ultraviolet (FUV) 900 - 1850 angstrom imaging spectrograph optimized for the study of diffuse emission. Its spectra will be used to study hot galactic plasmas, characterize the formation/destruction cycle and distribution of H2 in the ISM, and determine the optical properties of dust and its spatial distribution through the Galaxy. Galmatheia is a dual reflective spectrograph consisting of two elliptical diffraction gratings and a common cylindrical mirror, slit and detector. Its 5(sigma) sensitivity to C IV/O VI emission in a one-day pointing an order of magnitude fainter than any previous detection or to theoretical predictions.
