Paper Abstract

To illustrate the efficiency of using of a multi-mode deformable plane mirror to record holographic gratings we have computed the three gratings for the Cosmic Origin Spectrograph. Their working conditions are severe, since they have to correct the residual spherical aberration of the HST. Nevertheless, all the images obtained are largely diffraction-limited with regard to the resolution.
