An experimental study of the luminosity of an MFC−MAES-based digital spectrograph

详细

We experimentally investigated the dependence of luminosity of a digital spectrograph for the line spectrum on the input slit width in the range 5−100 μm for different ways of measuring the spectral line image intensity. Based on the results obtained, we showed that the spectrograph luminosity can be increased by more than an order of magnitude via a multiple increase in the input slit width over the normal one with a conserved minimum instrumental response function width.
