Paper Abstract

Toroidal gratings can be used for imaging spectrometers. These can provide stigmatic images and are very useful for space applications. Two cases are described: an Ultraviolet Coronagraph for the solar SOHO mission and a high resolution spectrometer for the stellar Lyman mission. The toroidal gratings have been produced by replicating an elastically deformed spherical one. By properly applying the distorting forces also coma-corrected surfaces can be achieved.
