Diffractive optical elements fabricated on flat and non-flat substrates frequently act as dispersive elements in imaging spectrometers. We describe the design and electron-beam fabrication of blazed and computer-generated-hologram gratings for slit and tomographic imaging spectrometers.

Applications were demonstrated for hybrid silicon infrared CCD arrays in both ground and space based astronomical instrumentation. The primary goal was to provide a point of departure for both instrument designs and further development of the device. The test device is an indium doped silicon (Si:In) version of the 32 x 32 Rockwell 30331 surface channel hybrid silicon IRCCD. The device structure and a typical instrument interface are shown. The motivation for further study is presented along with a discussion in detail of some of the issues.
