Abstract : A system of exact ray-tracing formulae has been developed for two spherical mirrors. The bundles of rays are supposed to be paralell between the mirrors. For a particular case, ie. the mirrors used in the horizontal spectrograph in the tower telescope at the Oslo Solar Observatory, the formulae have been used to determine the aberrations in the focal plane of the second mirror. The influence of the aberrations on the line profile has been found. (Author)
