Design and production of holographic gratings for grazing incidence spectrographs for use in the 5-200A region are described. The image plane of the spectrograph is flat over the distance of about 30mm so that multichannel real time photo-electric detection is possible with an array detector. A toroidal grating is adopted to avoid the light loss due to astigmatism, and its blank surface is tested with a modified point diffraction interferometer. The grating is recorded in Shipley AZ-1350 photoresist with an argon ion laser, and is coasted with gold after the development.
