OSIRIS - Grisms - Diffraction Efficiency

We show plots of the diffraction efficiency of the grisms. To obtain a broad description of the behaviour of the grisms, their efficiency curves have been computed in the required spectral range for TE and TM polarizations. The efficiency in natural light, which is simply the average of TE and TM efficiencies, is plotted in the figures.
