Scientific paper

For a spectrograph giving a fixed format spectrum, the quantum efficiency (QE) can be optimized for the different wavelengths across the CCD. It is shown that a slight modification of the conventional single layer anti-reflection coating can give major improvements in QE for such instruments, while at the same time minimizing problems with fringing and stray light from the CCD.
